Function Documentation

drawBuffer()

static void drawBuffer ( const SRPIndexBuffer *  ib, const SRPVertexBuffer *  vb, const SRPFramebuffer *  fb, const SRPShaderProgram *  sp, SRPPrimitive  primitive, size_t  startIndex, size_t  count  )

static

Draw either SRPIndexBuffer or SRPVertexBuffer. If ib == NULL, draws the vertex buffer, else draws index buffer. Created because vertex and index buffer drawing are very similar, with an intent to avoid code duplication

See also

srpDrawVertexBuffer() srpDrawIndexBuffer() for parameter documentation

indexIndexBuffer()

static uint64_t indexIndexBuffer ( const SRPIndexBuffer *  this, size_t  ibIndex  )

static

Get an element stored in SRPIndexBuffer. Needed because SRPIndexBuffer stores opaque index types.

Parameters

[in]	this	Pointer to SRPIndexBuffer
[in]	ibIndex	Index of the element in the SRPIndexBuffer

Returns

Element upcasted to uint64_t

indexVertexBuffer()

static SRPVertex * indexVertexBuffer ( const SRPVertexBuffer *  this, size_t  index  )

static

Get a vertex stored in SRPVertexBuffer.

Parameters

[in]	this	Pointer to SRPVertexBuffer
[in]	index	Index of the vertex to get

Returns

Requested vertex
