public void DrawIndexedPrimitives ( PrimitiveType primitiveType, int baseVertex, int minVertexIndex, int numVertices, int startIndex, int primitiveCount )
- Describes the type of primitive to render. PrimitiveType.PointList is not supported with this method.
- Offset to add to each vertex index in the index buffer.
- Minimum vertex index for vertices used during the call. The minVertexIndex parameter and all of the indices in the index stream are relative to the baseVertex parameter.
- A number of vertices used during the call. The first vertex is located at index: baseVertex + minVertexIndex.
- Location in the index array at which to start reading vertices.
- A number of primitives to render. The number of vertices used is a function of primitiveCount and primitiveType. To determine the maximum number of primitives allowed, check the MaxPrimitiveCount property member of the Capabilities structure.
|ArgumentOutOfRangeException||primitiveCount is less than or equal to zero. When drawing, at least one primitive must be drawn.|
One of the following conditions is true:
The vertex stream and index data of the graphics device must be set before any call to DrawIndexedPrimitives. The following example sets the index data and associates a user-created vertex buffer of type VertexPositionNormalTexture with vertex stream 0 (zero) of the graphics device.
This method draws indexed primitives from the current set of data input streams.
The minVertexIndex and numVertices parameters specify the range of vertex indices used for each call to DrawIndexedPrimitives. These vertex indices are used to optimize vertex processing of indexed primitives by processing a sequential range of vertices prior to indexing into them. Indices used during this call cannot reference any vertices outside this range.
If no index array is set, DrawIndexedPrimitives fails.
