Methods

Private allocVertexIdBuffer

destroy

  • destroy(): void

enableVertexIdChannel

  • enableVertexIdChannel(device: GFXDevice): void
  • en

    Adds a vertex attribute input called 'a_vertexId' into this sub-mesh. This is useful if you want to simulate gl_VertexId in WebGL context prior to 2.0. Once you call this function, the vertex attribute is permanently added. Subsequent calls to this function take no effect.

    Parameters

    • device: GFXDevice

      Device used to create related rendering resources.

    Returns void
