Class EXTClipControl

java.lang.Object

org.lwjgl.opengles.EXTClipControl

public class EXTClipControl
extends java.lang.Object

Native bindings to the EXT_clip_control extension.

This extension provides additional clip control modes to configure how clip space is mapped to window space. This extension's goal is to

1. allow OpenGL to effectively match Direct3D's coordinate system conventions, and
2. potentially improve the numerical precision of the Z coordinate mapping.

This extension is a port of GL_ARB_clip_control to OpenGL ES. For the complete overview of this extension, refer to the "Overview" section of GL_ARB_clip_control.
