Function Documentation

colorPack()

uint32_t colorPack ( float  color[4] )

inline

Pack a color represented via float[4] into uint32_t RGBA8888

srpFramebufferClear()

void srpFramebufferClear

(

Parameters

[in]

this

The pointer to SRPFramebuffer, as returned from srpNewFramebuffer()

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

Returns

A pointer to the created framebuffer
