- save()
Save the changes made to the object.
Generally a user does not need to call this function because it is called automatically at the end of a with block using Project.new() or Project.edit().
- attribute_names()
Returns a list containing the names of all object-level attributes. Use this to iterate over the object attributes.
- Returns
List containing the attribute names.
- Return type
list
Examples
Iterate over all object attributes of the object stared at “target” and print their values.
>>> from mapteksdk.project import Project >>> project = Project() >>> with project.read("target") as read_object: ... for name in read_object.attribute_names(): ... print(name, ":", read_object.get_attribute(name))
- close()
Closes the object and saves the changes to the Project, preventing any further changes.
- property coordinate_system
The coordinate system the points of this object are in.
Warning
Setting this property does not change the points. This is only a label stating the coordinate system the points are in.
Notes
If the object has no coordinate system, this will be None.
Changes are done directly in the project and will not be undone if an error occurs.
Examples
Creating an edge network and setting the coordinate system to be WGS84. Note that setting the coordinate system does not change the points. It is only stating which coordinate system the points are in.
>>> from pyproj import CRS >>> from mapteksdk.project import Project >>> from mapteksdk.data import Polygon >>> project = Project() >>> with project.new("cad/rectangle", Polygon) as new_edges: ... # Coordinates are in the form [longitude, latitude] ... new_edges.points = [[112, 9], [112, 44], [154, 44], [154, 9]] ... new_edges.coordinate_system = CRS.from_epsg(4326)
Often a standard map projection is not convenient or accurate for a given application. In such cases a local transform can be provided to allow coordinates to be specified in a more convenient system. The below example defines a local transform where the origin is translated 1.2 degrees north and 2.1 degree east, points are scaled to be twice as far from the horizontal origin and the coordinates are rotated 45 degrees clockwise about the horizontal_origin. Note that the points of the polygon are specified in the coordinate system after the local transform has been applied.
>>> import math >>> from pyproj import CRS >>> from mapteksdk.project import Project >>> from mapteksdk.data import Polygon, CoordinateSystem, LocalTransform >>> project = Project() >>> transform = LocalTransform( ... horizontal_origin = [1.2, 2.1], ... horizontal_scale_factor = 2, ... horizontal_rotation = math.pi / 4) >>> system = CoordinateSystem(CRS.from_epsg(20249), transform) >>> with project.new("cad/rectangle_transform", Polygon) as new_edges: ... new_edges.points = [[112, 9], [112, 44], [154, 44], [154, 9]] ... new_edges.coordinate_system = system

- Parameters
- Returns
True if the raster was successfully dissociated from the object, False if the raster was not associated with the object.
- Return type
bool
- Raises
TypeError – If raster is not a Raster.
Notes
This only removes the association between the Raster and the object, it does not clear the registration information from the Raster.
Examples
Dissociate the first raster found on a picked object.
>>> from mapteksdk.project import Project >>> from mapteksdk import operations >>> project = Project() >>> oid = operations.object_pick( ... support_label="Pick an object to remove a raster from.") ... with project.edit(oid) as data_object: ... report = f"There were no raster to remove from {oid.path}" ... for index in data_object.rasters: ... data_object.dissociate_raster(data_object.rasters[index]) ... report = f"Removed raster {index} from {oid.path}" ... break ... # Now that the raster is dissociated and the object is closed, ... # the raster can be associated with a different object. ... operations.write_report("Remove Raster", report)
- property extent

- Return type
any
- Raises
KeyError – If there is no object attribute called name.
Warning
In the future this function may be changed to return datetime.datetime and datetime.date objects instead of the current representation for object attributes of type datetime.datetime or datetime.date.

- Parameters
name (str) – Name of the attribute whose type should be returned.
- Returns

A dictionary of raster indices and Object IDs of the raster images currently associated with this object.
The keys are the raster ids and the values are the Object IDs of the associated rasters. Note that all raster ids are integers however they may not be consecutive - for example, an object may have raster ids 0, 1, 5 and 200.
Notes
Rasters with higher indices appear on top of rasters with lower indices. The maximum possible raster id is 255.
Removing a raster from this dictionary will not remove the raster association from the object. Use dissociate_raster to do this.
Examples
Iterate over all rasters on an object and invert the colours. Note that this will fail if there is no object at the path “target” and it will do nothing if no rasters are associated with the target.
>>> from mapteksdk.project import Project >>> project = Project() >>> with project.read("target") as read_object: ... for raster in read_object.rasters.values(): ... with project.edit(raster) as edit_raster: ... edit_raster.pixels[:, :3] = 255 - edit_raster.pixels[:, :3]
- set_attribute(name, dtype, data)
Sets the value for the object attribute with the specified name. This will overwrite any existing attribute with the specified name.
- Parameters
name (str) – The name of the object attribute for which the value should be set.
dtype (type) – The type of data to assign to the attribute. This should be a type from the ctypes module or datetime.datetime or datetime.date. Passing bool is equivalent to passing ctypes.c_bool. Passing str is equivalent to passing ctypes.c_char_p. Passing int is equivalent to passing ctypes.c_int16. Passing float is equivalent to passing ctypes.c_double.
data (any) – The value to assign to object attribute name. For dtype = datetime.datetime this can either be a datetime object or timestamp which will be passed directly to datetime.utcfromtimestamp(). For dtype = datetime.date this can either be a date object or a tuple of the form: (year, month, day).
- Raises
ValueError – If dtype is an unsupported type.
TypeError – If value is an inappropriate type for object attribute name.
RuntimeError – If a different error occurs.
Warning
Object attributes are saved separately from the object itself - any changes made by this function (assuming it does not raise an error) will be saved even if save() is not called (for example, due to an error being raised by another function).
Examples
Create an object attribute on an object at “target” and then read its value.
>>> import ctypes >>> from mapteksdk.project import Project >>> project = Project() >>> with project.edit("target") as edit_object: ... edit_object.set_attribute("count", ctypes.c_int16, 0) ... with project.read("target") as read_object: ... print(read_object.get_attribute("count")) 0

- class Text3D(object_id=None, lock_type=LockType.READWRITE)
Bases:
mapteksdk.data.annotations.TextAllows creation of three dimensional text at a fixed location and size in space.
- class Facing(value)
Bases:
enum.EnumEnum representing the possible facing values for 3D text.
- NO_FACING = 0
The text will not be camera or viewer facing. Depending on the angle it is viewed from, it may be upsidedown, back-to-front or both.
- CAMERA_FACING = 1
The text will rotate to always face towards the camera. Regardless of the angle it is viewed at, the text will never be upsidedown or back-to-front.
This causes direction and up direction of the text to be ignored.
- VIEWER_FACING = 2
The text will automatically flip so that it never appears upsidedown. Viewer facing text can still be back-to-front.
- classmethod static_type()
Return the type of 3D text as stored in a Project.
This can be used for determining if the type of an object is a 3D text.
- save()
Save the changes made to the object.
Generally a user does not need to call this function because it is called automatically at the end of a with block using Project.new() or Project.edit().
- property direction
The 3D direction vector of the text.
This is the direction vector from the start of the first character to the end of the last character.
- property up_direction
The 3D direction vector of the text.
This is the direction vector from the bottom of the text to the top.
- property always_visible
If the text will be visible through other objects.
If set to true, the 3D text will be visible with a faded out appearance when there are objects between the text and the view. This is False by default.
- Raises
TypeError – If set to a value which is not a bool.
- property facing
Where the text will face.
By default this is Text3D.Facing.VIEWER_FACING which causes the text to never appear upside down, even when viewed from the back.
See the values of the Text3D.Facing enum for possible options.
- Raises
TypeError – If set to a value which is not Text3D.Facing.
Examples
Set text containing a smiley face to be always camera facing so that it will always be smiling even when viewed from the back.
>>> from mapteksdk.project import Project >>> from mapteksdk.data import Text3D >>> project = Project() >>> with project.new("cad/smile", Text3D) as new_text: ... new_text.text = ":)" ... new_text.facing = Text3D.Facing.CAMERA_FACING

Changes are done directly in the project and will not be undone if an error occurs.
Examples
Creating an edge network and setting the coordinate system to be WGS84. Note that setting the coordinate system does not change the points. It is only stating which coordinate system the points are in.
>>> from pyproj import CRS >>> from mapteksdk.project import Project >>> from mapteksdk.data import Polygon >>> project = Project() >>> with project.new("cad/rectangle", Polygon) as new_edges: ... # Coordinates are in the form [longitude, latitude] ... new_edges.points = [[112, 9], [112, 44], [154, 44], [154, 9]] ... new_edges.coordinate_system = CRS.from_epsg(4326)
Often a standard map projection is not convenient or accurate for a given application. In such cases a local transform can be provided to allow coordinates to be specified in a more convenient system. The below example defines a local transform where the origin is translated 1.2 degrees north and 2.1 degree east, points are scaled to be twice as far from the horizontal origin and the coordinates are rotated 45 degrees clockwise about the horizontal_origin. Note that the points of the polygon are specified in the coordinate system after the local transform has been applied.
>>> import math >>> from pyproj import CRS >>> from mapteksdk.project import Project >>> from mapteksdk.data import Polygon, CoordinateSystem, LocalTransform >>> project = Project() >>> transform = LocalTransform( ... horizontal_origin = [1.2, 2.1], ... horizontal_scale_factor = 2, ... horizontal_rotation = math.pi / 4) >>> system = CoordinateSystem(CRS.from_epsg(20249), transform) >>> with project.new("cad/rectangle_transform", Polygon) as new_edges: ... new_edges.points = [[112, 9], [112, 44], [154, 44], [154, 9]] ... new_edges.coordinate_system = system

Notes
Rasters with higher indices appear on top of rasters with lower indices. The maximum possible raster id is 255.
Removing a raster from this dictionary will not remove the raster association from the object. Use dissociate_raster to do this.
Examples
Iterate over all rasters on an object and invert the colours. Note that this will fail if there is no object at the path “target” and it will do nothing if no rasters are associated with the target.
>>> from mapteksdk.project import Project >>> project = Project() >>> with project.read("target") as read_object: ... for raster in read_object.rasters.values(): ... with project.edit(raster) as edit_raster: ... edit_raster.pixels[:, :3] = 255 - edit_raster.pixels[:, :3]

For dtype = datetime.datetime this can either be a datetime object or timestamp which will be passed directly to datetime.utcfromtimestamp(). For dtype = datetime.date this can either be a date object or a tuple of the form: (year, month, day).
- Raises
ValueError – If dtype is an unsupported type.
TypeError – If value is an inappropriate type for object attribute name.
RuntimeError – If a different error occurs.
Warning
Object attributes are saved separately from the object itself - any changes made by this function (assuming it does not raise an error) will be saved even if save() is not called (for example, due to an error being raised by another function).
Examples
Create an object attribute on an object at “target” and then read its value.
>>> import ctypes >>> from mapteksdk.project import Project >>> project = Project() >>> with project.edit("target") as edit_object: ... edit_object.set_attribute("count", ctypes.c_int16, 0) ... with project.read("target") as read_object: ... print(read_object.get_attribute("count")) 0

- close()
Closes the object and saves the changes to the Project, preventing any further changes.
- property coordinate_system
The coordinate system the points of this object are in.
Warning
Setting this property does not change the points. This is only a label stating the coordinate system the points are in.
Notes
If the object has no coordinate system, this will be None.
Changes are done directly in the project and will not be undone if an error occurs.
Examples
Creating an edge network and setting the coordinate system to be WGS84. Note that setting the coordinate system does not change the points. It is only stating which coordinate system the points are in.

The returned values are in radians.
Notes
This is a derived property. It is recalculated each time this is called.
- property rasters
A dictionary of raster indices and Object IDs of the raster images currently associated with this object.
The keys are the raster ids and the values are the Object IDs of the associated rasters. Note that all raster ids are integers however they may not be consecutive - for example, an object may have raster ids 0, 1, 5 and 200.
Notes
Rasters with higher indices appear on top of rasters with lower indices. The maximum possible raster id is 255.
Removing a raster from this dictionary will not remove the raster association from the object. Use dissociate_raster to do this.
Examples
Iterate over all rasters on an object and invert the colours. Note that this will fail if there is no object at the path “target” and it will do nothing if no rasters are associated with the target.
>>> from mapteksdk.project import Project >>> project = Project() >>> with project.read("target") as read_object: ... for raster in read_object.rasters.values(): ... with project.edit(raster) as edit_raster: ... edit_raster.pixels[:, :3] = 255 - edit_raster.pixels[:, :3]
- rotate(angle, axis)
Rotates the object by the specified angle around the specified axis.
- Parameters
angle (float) – The angle to rotate by in radians. Positive is clockwise, negative is anticlockwise (When looking in the direction of axis).
axis (Axis) – The axis to rotate by.
Examples
Create a 2x2x2 dense block model which is rotated by pi / 4 radians (45 degrees) around the X axis.
>>> import math >>> from mapteksdk.project import Project >>> from mapteksdk.data import DenseBlockModel, Axis >>> project = Project() >>> with project.new("blockmodels/dense_rotated", DenseBlockModel( ... x_res=1, y_res=1, z_res=1, ... x_count=2, y_count=2, z_count=3)) as new_model: ... new_model.rotate(math.pi / 4, Axis.X)
If you want to specify the angle in degrees instead of radians, use the math.radians function. Additionally rotate can be called multiple times to rotate the block model in multiple axes. Both of these are shown in the below example. The resulting block model is rotated 32 degrees around the Y axis and 97 degrees around the Z axis.
>>> import math >>> from mapteksdk.project import Project >>> from mapteksdk.data import DenseBlockModel, Axis >>> project = Project() >>> with project.new("blockmodels/dense_rotated_degrees", DenseBlockModel( ... x_res=1, y_res=1, z_res=1, ... x_count=2, y_count=2, z_count=3)) as new_model: ... new_model.rotate(math.radians(32), Axis.Y) ... new_model.rotate(math.radians(97), Axis.Z)
- rotate_2d(angle)
Rotates the object in two dimensions. This is equivalent to rotate with axis=Axis.Z
- Parameters
angle (float) – The angle to rotate by in radians. Positive is clockwise, negative is anticlockwise.
- property rotation
Returns the magnitude of the rotation of the object in radians.
This value is the total rotation of the object relative to its original position.
Notes
If the object has been rotated in multiple axes, this will not be the sum of the rotations performed. For example, a rotation of 90 degrees around the X axis, followed by a rotation of 90 degrees around the Y axis corresponds to a single rotation of 120 degrees so this function would return (2 * pi) / 3 radians.
- set_attribute(name, dtype, data)
Sets the value for the object attribute with the specified name. This will overwrite any existing attribute with the specified name.
- Parameters
name (str) – The name of the object attribute for which the value should be set.
dtype (type) – The type of data to assign to the attribute. This should be a type from the ctypes module or datetime.datetime or datetime.date. Passing bool is equivalent to passing ctypes.c_bool. Passing str is equivalent to passing ctypes.c_char_p. Passing int is equivalent to passing ctypes.c_int16. Passing float is equivalent to passing ctypes.c_double.
data (any) – The value to assign to object attribute name. For dtype = datetime.datetime this can either be a datetime object or timestamp which will be passed directly to datetime.utcfromtimestamp(). For dtype = datetime.date this can either be a date object or a tuple of the form: (year, month, day).
- Raises
ValueError – If dtype is an unsupported type.
TypeError – If value is an inappropriate type for object attribute name.
RuntimeError – If a different error occurs.
Warning
Object attributes are saved separately from the object itself - any changes made by this function (assuming it does not raise an error) will be saved even if save() is not called (for example, due to an error being raised by another function).
Examples
Create an object attribute on an object at “target” and then read its value.
>>> import ctypes >>> from mapteksdk.project import Project >>> project = Project() >>> with project.edit("target") as edit_object: ... edit_object.set_attribute("count", ctypes.c_int16, 0) ... with project.read("target") as read_object: ... print(read_object.get_attribute("count")) 0
- set_orientation(dip, plunge, bearing)
Overwrite the existing rotation with a rotation defined by the specified dip, plunge and bearing.
An orientation of (dip, plunge, bearing) radians is equivalent to rotating the model -dip radians around the X axis, -plunge radians around the Y axis and -(bearing - pi / 2) radians around the Z axis.
- Parameters
dip (float) – Relative rotation of the Y axis around the X axis in radians. This should be between -pi and pi (inclusive).
plunge (float) – Relative rotation of the X axis around the Y axis in radians. This should be between -pi / 2 and pi / 2 (exclusive).
bearing (float) – Absolute bearing of the X axis around the Z axis in radians. This should be between -pi and pi (inclusive).
- Raises
TypeError – If dip, plunge or bearing are not numbers.
Examples
Set orientation of a new 3x3x3 block model to be plunge = 45 degrees, dip = 30 degrees and bearing = -50 degrees
>>> import math >>> from mapteksdk.project import Project >>> from mapteksdk.data import DenseBlockModel >>> project = Project() >>> with project.new("blockmodels/model_1", DenseBlockModel( ... x_res=1, y_res=1, z_res=1, ... x_count=3, y_count=3, z_count=3)) as new_model: >>> new_model.set_orientation(math.radians(45), ... math.radians(30), ... math.radians(-50))
Copy the rotation from one block model to another. Requires two block models.
>>> from mapteksdk.project import Project >>> from mapteksdk.data import DenseBlockModel >>> project = Project() >>> with project.edit("blockmodels/model_1") as model_1: ... with project.edit("blockmodels/model_2") as model_2: ... model_2.set_orientation(*model_1.orientation)
- set_rotation(angle, axis)

axis (Axis) – Axis to rotate around.
- set_rotation_2d(angle)
Overwrite the existing rotation with a simple 2d rotation.
- Parameters
angle (float) – Angle to set the rotation to in radians.
- classmethod static_type()
Return the type of marker as stored in a Project.
This can be used for determining if the type of an object is a marker.
- get_properties()

- property shape
What shape the marker takes in a view. Must be from the Marker.Shape enum.
- property custom_shape_object
The ObjectID of the surface used for the custom marker shape. For best results the surface should be centred at [0, 0, 0] and should fit within a unit sphere centred at the origin.
Notes
Set this to None to remove the custom shape of the marker.
- Raises
TypeError – If set to a value which cannot be converted to an ObjectID.
ValueError – If set to an ObjectID which is not for a Surface.
Examples
Creating a tetrahedron shaped marker at [10, 10, 10] using a custom surface.
>>> import math >>> from mapteksdk.project import Project >>> from mapteksdk.data import Marker, Surface >>> x = 1 / math.sqrt(2) >>> points = [[1, 0, -x], [-1, 0, -x], [0, 1, x], [0, -1, x]] >>> facets = [[2, 0, 1], [0, 3, 1], [2, 1, 3], [0, 2, 3]] >>> project = Project() >>> with project.new("surfaces/tetra_base", Surface) as new_tetrahedron: ... new_tetrahedron.points = points ... new_tetrahedron.facets = facets >>> with project.new("cad/tetra_marker", Marker) as new_marker: ... new_marker.text = "tetrahedron" ... new_marker.custom_shape_object = new_tetrahedron ... new_marker.location = [10, 10, 10]
- property location
Position of the marker as a point ([x,y,z]).
- property size
The size of the marker in meters. The default is 1.0.
For a marker with a custom shape, the actual size of the marker is the size of the custom shape object multiplied by this property.
- Raises
ValueError – If set to a value which cannot be converted to a float.
TypeError – If set to a type which cannot be converted to a float.
- property text_colour
The colour of the text on the marker, represented as an RGBA colour. Colour may be set to a RGB, RGBA or greyscale colour.
See also
marker_colourThe colour of the marker itself.
- property marker_colour
The colour of the marker, represented as an RGBA colour (However when setting the colour you may use a greyscale or RGB colour).
See also
text_colourThe colour of the text on the marker.
Notes
marker.marker_colour = None will set the marker colour to the default yellow ([255, 255, 0, 255]).
Marker colour is currently ignored by markers with custom shapes, however it is intended to be implemented in the future.
The alpha value of the marker colour is currently ignored, though may be supported in the future. It is recommended to either set marker colour to be an RGB colour or to set the alpha value to 255.
