Class ARBES2Compatibility


  • public class ARBES2Compatibility
    extends java.lang.Object
    Native bindings to the ARB_ES2_compatibility extension.

    This extension adds support for features of OpenGL ES 2.0 that are missing from OpenGL 3.x. Enabling these features will ease the process of porting applications from OpenGL ES 2.0 to OpenGL.

    Promoted to core in OpenGL 4.1.

      • glReleaseShaderCompiler

        public static void glReleaseShaderCompiler()
        Releases resources allocated by the shader compiler. This is a hint from the application, and does not prevent later use of the shader compiler.
