Package org.lwjgl.opengl

Class ARBES2Compatibility

java.lang.Object

org.lwjgl.opengl.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.

Method Detail

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.

glShaderBinary

public static void glShaderBinary(java.nio.IntBuffer shaders,
                                  int binaryformat,
                                  java.nio.ByteBuffer binary)

Loads pre-compiled shader binaries.

Parameters:

shaders - an array of shader handles into which to load pre-compiled shader binaries

binaryformat - the format of the shader binaries contained in binary

binary - an array of bytes containing pre-compiled binary shader code

glGetShaderPrecisionFormat

public static void glGetShaderPrecisionFormat(int shadertype,
                                              int precisiontype,
                                              java.nio.IntBuffer range,
                                              java.nio.IntBuffer precision)

Retrieves the range and precision for numeric formats supported by the shader compiler.

Parameters:

shadertype - the type of shader whose precision to query. One of:

VERTEX_SHADER

FRAGMENT_SHADER

precisiontype - the numeric format whose precision and range to query

range - the address of array of two integers into which encodings of the implementation's numeric range are returned

precision - the address of an integer into which the numeric precision of the implementation is written
