jevois::GPUtexture Class Reference

#include <jevois/GPU/GPUtexture.H>

Simple class to hold an OpenGL texture.

OpenGL textures are used to transfer image data from CPU to GPU and then allow the GPU to perform some processing on the data. Processing is typically done by using "shader" GPU programs that transform the texture's pixel data and render it, in some user-programmable way.

Constructor & Destructor Documentation

GPUtexture()

jevois::GPUtexture::GPUtexture	(	GLsizei	width,
		GLsizei	height,
		GLenum	format,
		bool	createFramebuffer
	)

Constructor.

format should be as in glTexImage2D(), typically only GL_RGBA or GL_LUMINANCE are supported on embedded hardware platforms.

~GPUtexture()

jevois::GPUtexture::~GPUtexture

(

)

Destructor, frees the texture in OpenGL.

Member Function Documentation

getPixels()

void jevois::GPUtexture::getPixels

(

void *

data

)

const

Copy pixel data from the texture to already-allocated memory location.

data should have been allocated by caller and have the correct size given the textute width, height, and format.

setPixels()

void jevois::GPUtexture::setPixels

(

void const *

data

)

Copy pixel data from memory location to the texture.

data should have been allocated by caller and have the correct size given the textute width, height, and format.
