public void DrawPrimitives ( PrimitiveType primitiveType, int startVertex, int primitiveCount )
- Describes the type of primitive to render.
- Index of the first vertex to load. Beginning at startVertex, the correct number of vertices is read out of the vertex buffer.
- Number of primitives to render. To determine the maximum number of primitives allowed, check MaxPrimitiveCount. The primitiveCount is the number of primitives as determined by the primitive type. If it is a line list, each primitive has two vertices. If it is a triangle list, each primitive has three vertices.
|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 of the graphics device must be set before any call to DrawPrimitives. The following example associates a user created vertex buffer of type VertexPositionNormalTexture with vertex stream 0 (zero) of the graphics device.
