Class EXTTextureSnorm

java.lang.Object

org.lwjgl.opengl.EXTTextureSnorm

public final class EXTTextureSnorm
extends java.lang.Object

Native bindings to the EXT_texture_snorm extension.

Fixed-point textures in unextended OpenGL have integer components, but those values are taken to represent floating-point values in the range [0.0,1.0]. These integer components are considered "unsigned normalized" integers. When such a texture is accessed by a shader or by fixed-function fragment processing, floating-point values are returned in the range [0.0,1.0].

This extension provides a set of new "signed normalized" integer texture formats. These are taken to represent a floating-point value in the range [-1.0,1.0] with an exact 0.0.

Requires OpenGL 3.0.
