Patch class

A Patch is a parametric modeling surface, similar to NurbsSurface, it’s also defined by two PatchDirection, the Patch.u and Patch.v.

Inheritance: Patch → Geometry → Entity → SceneObject → A3DObject

The Patch type exposes the following members:

Constructor	Description
init	Initializes a new instance of the `Patch` class.
init	Initializes a new instance of the `Patch` class.

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
u	Gets the u direction.
v	Gets the v direction.

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.
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
