GL_OES_byte_coordinates

Supported Hardware

Series5, Series5XT, Series6, Series6XE, Series6XT

Valid APIs

OpenGL ES 1.x

Description

This extension allows users to pass byte values as texture coordinates and vertex positions in OpenGL ES 1.x, which are otherwise not allowed by the API. Byte sized data has the advantage of consuming less bandwidth than larger types and can be useful for certain scenes.

Note

This functionality is superseded by programmable shader support in subsequent versions of OpenGL ES.

Example

// Input byte coordinates 
GLbyte coordinates[] = 
{ 
	0, 255, 0, 
	255, 255, 0, 
	255, 0, 0, 
}; 
// Give the coordinates to OpenGL ES 
glVertexPointer(3, GL_BYTE, 0, coordinates);
