Detailed Description

Draw dispatch functions.

Function Documentation

checkOOB()

static bool checkOOB ( const SRPIndexBuffer *  ib, const SRPVertexBuffer *  vb, size_t  startIndex, size_t  count  )

static

Check if the draw call tries to access out-of-bounds memory and if so, send an error message

drawBuffer() for parameter documentation

drawBuffer()

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

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

drawLines()

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

static

Draw line-based primitives from either SRPIndexBuffer or SRPVertexBuffer

drawPoints()

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

static

Draw points from either SRPIndexBuffer or SRPVertexBuffer
