interface IPrimitiveRenderer in Tinman.Terrain.Rendering

Base interface for classes that provide methods for drawing graphic primitives (both indexed and non-indexed).

Methods

DrawPrimitives

Draws primitives.

method	DrawPrimitives (Primitive primitive, int32 firstVertex, int32 vertexCount)
params	primitive		The type of primitive to draw.
	firstVertex	[>=0]	First vertex to draw.
	vertexCount	[>=0]	The number of vertices to draw (not ! primitive count).

Remarks:

The vertices are stored in an IVertexBuffer object. The application is responsible for setting the proper render states.

DrawPrimitivesIndexed

Draws indexed primitives.

method	DrawPrimitivesIndexed (Primitive primitive, int32 firstIndex, int32 indexCount, int32 baseIndex = 0)
params	primitive		The type of primitive to draw.
	firstIndex	[>=0]	First vertex index to draw.
	indexCount	[>=0]	The number of vertex indices to draw (not ! primitive count).
	baseIndex	[>=0]	Optional base index value. The base index will be added to each vertex index during rendering.

Remarks:

The vertex indices of the primitive are stored in an IIndexBuffer object, the vertices are stored in an IVertexBuffer object. The application is responsible for setting the proper render states.

Exactly indexCount indices will read from the index buffer, starting at the buffer index firstIndex (not ! byte offset).
