Class QCOMAlphaTest

java.lang.Object
org.lwjgl.opengles.QCOMAlphaTest
public class QCOMAlphaTest extends Object
Native bindings to the QCOM_alpha_test extension.

This extension reintroduces the alpha test per-fragment operation from OpenGL ES 1.x. Some hardware has a dedicated unit capable of performing this operation, and it can save ALU operations in the fragment shader by avoiding the conditional discard.
