Methods
get
-
Returns an array of integers or a typed array (Int32Array, Uint32Array, Uint16Array) populated with the mesh indices.
Parameters
-
Optional copyWhenShared: boolean
If true (default false) and and if the mesh geometry is shared among some other meshes, the returned array is a copy of the internal one.
-
Optional forceCopy: boolean
defines a boolean indicating that the returned array must be cloned upon returning it
Returns Nullable<IndicesArray>
the indices array or an empty array if the mesh has no geometry
-
get
-
Gets a specific vertex data attached to this geometry. Float data is constructed if the vertex buffer data cannot be returned directly.
Parameters
-
kind: string
defines the data kind (Position, normal, etc...)
-
Optional copyWhenShared: boolean
defines if the returned array must be cloned upon returning it if the current geometry is shared between multiple meshes
-
Optional forceCopy: boolean
defines a boolean indicating that the returned array must be cloned upon returning it
Returns Nullable<FloatArray>
a float array containing vertex data
-
is
-
Gets a boolean indicating if specific vertex data is present
Parameters
-
kind: string
defines the vertex data kind to use
Returns boolean
true is data kind is present
-
set
-
Creates a new index buffer
Parameters
-
indices: IndicesArray
defines the indices to store in the index buffer
-
totalVertices: Nullable<number>
defines the total number of vertices (could be null)
-
Optional updatable: boolean
defines if the index buffer must be flagged as updatable (false by default)
Returns void
-
set
-
Set specific vertex data
Parameters
-
kind: string
defines the data kind (Position, normal, etc...)
-
data: FloatArray
defines the vertex data to use
-
updatable: boolean
defines if the vertex must be flagged as updatable (false as default)
Returns void
-
update
-
Update a specific associated vertex buffer
Parameters
-
kind: string
defines which buffer to write to (positions, indices, normals, etc). Possible
kindvalues :- VertexBuffer.PositionKind
- VertexBuffer.UVKind
- VertexBuffer.UV2Kind
- VertexBuffer.UV3Kind
- VertexBuffer.UV4Kind
- VertexBuffer.UV5Kind
- VertexBuffer.UV6Kind
- VertexBuffer.ColorKind
- VertexBuffer.MatricesIndicesKind
- VertexBuffer.MatricesIndicesExtraKind
- VertexBuffer.MatricesWeightsKind
- VertexBuffer.MatricesWeightsExtraKind
-
data: FloatArray
defines the data source
-
Optional updateExtends: boolean
defines if extends info of the mesh must be updated (can be null). This is mostly useful for "position" kind
-
Optional makeItUnique: boolean
defines if the geometry associated with the mesh must be cloned to make the change only for this mesh (and not all meshes associated with the same geometry)
Returns void
-
Define an interface for all classes that will get and set the data on vertices
