Detailed Description

Internals of the Framebuffer module.

Function Documentation

void framebufferGetColorAndDepthPointers	(	const SRPFramebuffer *	this,
		size_t	x,
		size_t	y,
		uint32_t **	pColor,
		float **	pDepth
	)

Get pointers inside color and depth buffers for pixel at (x, y)

Parameters

[in]	this	Pointer to the SRPFramebuffer
[in]	x,y	Coordinates of the needed pixel
[out]	pColor	Pointer to the color buffer
[out]	pDepth	Pointer to the depth buffer

void framebufferNDCToScreenSpace	(	const SRPFramebuffer *	this,
		const float *	NDC,
		float *	SS
	)

Convert Normalized Device Coordinates to screen-space coordiantes

Parameters

[in]	this	The pointer to SRPFramebuffer, as returned from srpNewFramebuffer
[in]	NDC	Pointer to 3-element float array containing NDC position
[out]	SS	Pointer to 3-element float array that will contain SS position after the call. The z-component is the same as z-component of NDC coordinates.

void srpFramebufferClear ( const SRPFramebuffer * this )

Clear a framebuffer: fill the color with black and depth with -1

Parameters

[in] this The pointer to SRPFramebuffer, as returned from srpNewFramebuffer()

void srpFreeFramebuffer ( SRPFramebuffer * this )

Free a framebuffer

Parameters

[in] this The pointer to SRPFramebuffer, as returned from srpNewFramebuffer()

SRPFramebuffer * srpNewFramebuffer	(	size_t	width,
		size_t	height
	)

Create a framebuffer

Parameters

[in]	width	Width of a new framebuffer in pixels
[in]	height	Height of a new framebuffer in pixels
