Description
Provides a mechanism to draw the specified primitives.
The DoDrawPrimitives method provides a mechanism to draw the specified primitives without limitations. DoDrawPrimitives either draws the primitives directly in the hardware, or divides the buffers in batches and calls DoDrawPrimitivesBatch to render each individual batch.
DoDrawPrimitives takes the following parameters:
| Parameter | Description |
|---|---|
AKind
|
The kind of primitive: Points, Lines, or Triangles.
|
Vertices
|
Pointer to the vertices data. |
Indices
|
Pointer to the indices data. |
VertexDeclaration
|
The definition of the vertices. |
VertexSize
|
The size of the vertices in the buffer. |
VertexCount
|
The number of vertices in the buffer. |
IndexSize
|
The size of the indices in the buffer. |
IndexCount
|
The number of indices in the buffer. |
