53 \class QGLShaderProgram -

54 \inmodule QtOpenGL -

55 \brief The QGLShaderProgram class allows OpenGL shader programs to be linked and used. -

56 \since 4.6 -

57 \obsolete -

58 \ingroup painting-3D -

59 -

60 \section1 Introduction -

61 -

62 This class supports shader programs written in the OpenGL Shading -

63 Language (GLSL) and in the OpenGL/ES Shading Language (GLSL/ES). -

64 -

65 QGLShader and QGLShaderProgram shelter the programmer from the details of -

66 compiling and linking vertex and fragment shaders. -

67 -

68 The following example creates a vertex shader program using the -

69 supplied source \c{code}. Once compiled and linked, the shader -

70 program is activated in the current QGLContext by calling -

71 QGLShaderProgram::bind(): -

72 -

73 \snippet code/src_opengl_qglshaderprogram.cpp 0 -

74 -

75 \section1 Writing Portable Shaders -

76 -

77 Shader programs can be difficult to reuse across OpenGL implementations -

78 because of varying levels of support for standard vertex attributes and -

79 uniform variables. In particular, GLSL/ES lacks all of the -

80 standard variables that are present on desktop OpenGL systems: -

81 \c{gl_Vertex}, \c{gl_Normal}, \c{gl_Color}, and so on. Desktop OpenGL -

82 lacks the variable qualifiers \c{highp}, \c{mediump}, and \c{lowp}. -

83 -

84 The QGLShaderProgram class makes the process of writing portable shaders -

85 easier by prefixing all shader programs with the following lines on -

86 desktop OpenGL: -

87 -

88 \code -

89 #define highp -

90 #define mediump -

91 #define lowp -

92 \endcode -

93 -

94 This makes it possible to run most GLSL/ES shader programs -

95 on desktop systems. The programmer should restrict themselves -

96 to just features that are present in GLSL/ES, and avoid -

97 standard variable names that only work on the desktop. -

98 -

99 \section1 Simple Shader Example -

100 -

101 \snippet code/src_opengl_qglshaderprogram.cpp 1 -

102 -

103 With the above shader program active, we can draw a green triangle -

104 as follows: -

105 -

106 \snippet code/src_opengl_qglshaderprogram.cpp 2 -

107 -

108 \section1 Binary Shaders and Programs -

109 -

110 Binary shaders may be specified using \c{glShaderBinary()} on -

111 the return value from QGLShader::shaderId(). The QGLShader instance -

112 containing the binary can then be added to the shader program with -

113 addShader() and linked in the usual fashion with link(). -

114 -

115 Binary programs may be specified using \c{glProgramBinaryOES()} -

116 on the return value from programId(). Then the application should -

117 call link(), which will notice that the program has already been -

118 specified and linked, allowing other operations to be performed -

119 on the shader program. -
