Mesh class

Mesh class

A mesh is made of many n-sided polygons.

Inheritance: Mesh → Geometry → Entity → SceneObject → A3DObject

The Mesh type exposes the following members:

Constructors

Constructor	Description
init	Initializes a new instance of the Mesh class.
init	Construct a mesh using specified height map, if the height map’s pixel format contains multiple components, the first(usually the red) component will be used as the height value(z) The control point’s x and y components are normalized pixel coordinate.
init	Construct a mesh using specified height map, if the height map’s pixel format contains multiple components, the first(usually the red) component will be used as the height value(z) The control point’s x and y components are normalized pixel coordinate.

Properties

Property	Description
name	Gets or sets the name.
properties	Gets the collection of all properties.
scene	Gets the scene that this object belongs to
parent_nodes	Gets all parent nodes, an entity can be attached to multiple parent nodes for geometry instancing
excluded	Gets or sets whether to exclude this entity during exporting.
parent_node	Gets or sets the first parent node, if set the first parent node, this entity will be detached from other parent nodes.
visible	Gets or sets if the geometry is visible
deformers	Gets all deformers associated with this geometry.
control_points	Gets all control points
cast_shadows	Gets or sets whether this geometry can cast shadow
receive_shadows	Gets or sets whether this geometry can receive shadow.
vertex_elements	Gets all vertex elements
edges	Gets edges of the Mesh. Edge is optional in mesh, so it can be empty.
polygon_count	Gets the count of polygons
polygons	Gets the polygons definition of the mesh

Methods

Method	Description
remove_property	Removes a dynamic property.
remove_property	Remove the specified property identified by name
create_element	Creates a vertex element with specified type and add it to the geometry.
create_element	Creates a vertex element with specified type and add it to the geometry.
create_element_uv	Creates a VertexElementUV with given texture mapping type.
create_element_uv	Creates a VertexElementUV with given texture mapping type.
create_polygon	Creates a new polygon with all vertices defined in indices. To create polygon vertex by vertex, please use PolygonBuilder.
create_polygon	Creates a new polygon with all vertices defined in indices. To create polygon vertex by vertex, please use PolygonBuilder.
create_polygon	Create a polygon with 4 vertices(quad)
create_polygon	Create a polygon with 3 vertices(triangle)
get_property	Get the value of specified property
set_property	Sets the value of specified property
find_property	Finds the property. It can be a dynamic property (Created by CreateDynamicProperty/SetProperty) or native property(Identified by its name)
get_bounding_box	Gets the bounding box of current entity in its object space coordinate system.
get_entity_renderer_key	Gets the key of the entity renderer registered in the renderer
get_element	Gets a vertex element with specified type
get_vertex_element_of_uv	Gets a VertexElementUV instance with given texture mapping type
add_element	Adds an existing vertex element to current geometry
get_polygon_size	Gets the vertex count of the specified polygon.
to_mesh	Gets the Mesh instance from current entity.
do_boolean
union	Calculate the union of two meshes
difference	Calculate the difference of two meshes
intersect	Calculate the intersection of two meshes
optimize	Optimize the mesh’s memory usage by eliminating duplicated control points

Example

To add a polygon in mesh:

from aspose.threed.entities import Mesh

mesh = Mesh()
indices = [0, 1, 2]
mesh.create_polygon(indices)

Travel through all polygons in mesh:

from aspose.threed.entities import Mesh

mesh = Mesh()
for polygon in mesh:
    pass
