Method Summary

Modifier and TypeMethod and Description
public static void
attachShader(final GL _gl, final int program, final IntBuffer shaders)

public static void
compileShader(final GL _gl, final IntBuffer shaders)

public static boolean
createAndCompileShader(final GL _gl, final IntBuffer shader, final int shaderType, final CharSequence[][] sources, final PrintStream verboseOut)

public static boolean
createAndLoadShader(final GL _gl, final IntBuffer shader, final int shaderType, final int binFormat, final Buffer bin, final PrintStream verboseOut)

public static void
createShader(final GL _gl, final int type, final IntBuffer shaders)

public static void
deleteShader(final GL _gl, final IntBuffer shaders)

public static void

private static ShaderUtil.ProfileInformation
getProfileInformation(final GL gl)

public static String
getProgramInfoLog(final GL _gl, final int programObj)

public static Set<Integer>
getShaderBinaryFormats(final GL _gl)

If supported, queries the natively supported shader binary formats using GL2ES2#GL_NUM_SHADER_BINARY_FORMATS and GL2ES2#GL_SHADER_BINARY_FORMATS via GL2ES2#glGetIntegerv(int, int[], int).

public static String
getShaderInfoLog(final GL _gl, final int shaderObj)

public static boolean
isGeometryShaderSupported(final GL _gl)

Returns true if GeometryShader is supported, i.e. whether GLContext is ≥ 3.2 or ARB_geometry_shader4 extension is available.

public static boolean
isProgramExecStatusValid(final GL _gl, final int programObj, final PrintStream verboseOut)

Performs GL2ES2#glValidateProgram(int)

One shall only call this method while debugging and only if all required resources by the shader are set.

public static boolean
isProgramLinkStatusValid(final GL _gl, final int programObj, final PrintStream verboseOut)

public static boolean
isProgramStatusValid(final GL _gl, final int programObj, final int name)

public static boolean
isShaderCompilerAvailable(final GL _gl)

Returns true if a hader compiler is available, otherwise false.

public static boolean

Performs GL2ES2#glValidateProgram(int)

One shall only call this method while debugging and only if all required resources by the shader are set.

Note

It is possible that a working shader program will fail validation. This has been experienced on NVidia APX2500 and Tegra2.
