MeshBuffer
Deprecated: It is planned to render this class obsolete and rely on three.js’s BufferGeometry.
Instancing
Some 3D rendering pipelines support instancing, which is a technique for rendering multiple versions of a mesh buffer with a single draw call. Instancing involves the use of a second mesh buffer (an instance buffer); rather than holding vertex data, the instance buffer holds instance data, that is, data to be used when rendering each instance of the first mesh buffer. Besides this, however, instance buffers are largely similar to vertex buffers as far as the MeshBuffer class is concerned; any reference to vertices in the documentation applies analogously to instances in instance buffers. However, instance buffers should have only one vertex per primitive; it makes little sense to have instance buffers describe triangles or line segments.
Members
- LINES
Indicates that a mesh buffer contains line segments; the mesh buffer stores each line segment using two consecutive vertices. - POINTS
Indicates that a mesh buffer contains points; the mesh buffer stores each point using one vertex. - TRIANGLES
Indicates that a mesh buffer contains triangles; the mesh buffer stores each triangle using three consecutive vertices.
### MeshBuffer.LINES (constant)
Indicates that a mesh buffer contains line segments; the mesh buffer stores each line segment using two consecutive vertices.
Default Value: 1
### MeshBuffer.POINTS (constant)
Indicates that a mesh buffer contains points; the mesh buffer stores each point using one vertex.
Default Value: 0
### MeshBuffer.TRIANGLES (constant)
Indicates that a mesh buffer contains triangles; the mesh buffer stores each triangle using three consecutive vertices.
Default Value: 4
