Package org.lwjgl.opengl

Class ARBTextureBorderClamp

java.lang.Object

org.lwjgl.opengl.ARBTextureBorderClamp

public final class ARBTextureBorderClamp
extends java.lang.Object

Native bindings to the ARB_texture_border_clamp extension.

The base OpenGL provides clamping such that the texture coordinates are limited to exactly the range [0,1]. When a texture coordinate is clamped using this algorithm, the texture sampling filter straddles the edge of the texture image, taking 1/2 its sample values from within the texture image, and the other 1/2 from the texture border. It is sometimes desirable for a texture to be clamped to the border color, rather than to an average of the border and edge colors.

This extension defines an additional texture clamping algorithm. CLAMP_TO_BORDER_ARB clamps texture coordinates at all mipmap levels such that NEAREST and LINEAR filters return only the color of the border texels.

Promoted to core in OpenGL 1.3.
