    • getShaderInfoLog

      public static String getShaderInfoLog(GL _gl, int shaderObj)

    • getProgramInfoLog

      public static String getProgramInfoLog(GL _gl, int programObj)

    • isShaderStatusValid

      public static boolean isShaderStatusValid(GL _gl, int shaderObj, int name, PrintStream verboseOut)

    • isShaderStatusValid

      public static boolean isShaderStatusValid(GL _gl, IntBuffer shaders, int name, PrintStream verboseOut)

    • isProgramStatusValid

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

    • isProgramLinkStatusValid

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

    • isProgramExecStatusValid

      public static boolean isProgramExecStatusValid(GL _gl, int programObj, 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.

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

      public static boolean isGeometryShaderSupported(GL _gl)
      Returns true if GeometryShader is supported, i.e. whether GLContext is ≥ 3.2 or ARB_geometry_shader4 extension is available.
