ModelProcessor.ProcessVertexChannel Method

Note

This method is available only when developing for Windows.

Processes geometry content vertex channels at the specified index.

Syntax

'Declaration
Protected Overridable Sub ProcessVertexChannel ( _
         geometry As GeometryContent, _
         vertexChannelIndex As Integer, _
         context As ContentProcessorContext _
)

protected virtual void ProcessVertexChannel (
         GeometryContent geometry,
         int vertexChannelIndex,
         ContentProcessorContext context
)

protected:
virtual void ProcessVertexChannel(
         GeometryContent geometry,
         int vertexChannelIndex,
         ContentProcessorContext context
)

Parameters

• geometry
  Type: GeometryContent
  The geometry content to process.
• vertexChannelIndex
  Type: Int32
  Index of the vertex channel to process.
• context
  Type: ContentProcessorContext
  Context for the specified processor.

Remarks

This function will be called for each VertexChannel of Vertices found in the input mesh. Subclasses of ModelProcessor can override ProcessVertexChannel to control how vertex data is processed. The default implementation converts VertexElementUsage.Color channels to Color format, and replaces Weights channels with a pair of VertexElementUsage.BlendIndices and VertexElementUsage.BlendIndices channels (using Byte4 format for the VertexElementUsage.BlendWeight, Color for the VertexElementUsage.BlendWeight, and discarding excess weights if there are more than four per vertex).
