+ \class QGLShaderProgram
+ \brief The QGLShaderProgram class allows OpenGL shader programs to be linked and used.
+ \since 4.6
+
+ \section1 Introduction
+
+ This class supports shader programs written in the OpenGL Shading
+ Language (GLSL) and in the OpenGL/ES Shading Language (GLSL/ES).
+
+ QGLShader and QGLShaderProgram shelter the programmer from the details of
+ compiling and linking vertex and fragment shaders.
+
+ The following example creates a vertex shader program using the
+ supplied source \c{code}. Once compiled and linked, the shader
+ program is activated in the current QGLContext by calling
+ QGLShaderProgram::enable():
+
+ \code
+ QGLShader shader(QGLShader::VertexShader);
+ shader.setSourceCode(code);
+
+ QGLShaderProgram program(context);
+ program.addShader(shader);
+ program.link();
+
+ program.enable();
+ \endcode
+
+ \section1 Writing portable shaders
+
+ Shader programs can be difficult to reuse across OpenGL implementations
+ because of varying levels of support for standard vertex attributes and
+ uniform variables. In particular, GLSL/ES lacks all of the
+ standard variables that are present on desktop OpenGL systems:
+ \c{gl_Vertex}, \c{gl_Normal}, \c{gl_Color}, and so on. Desktop OpenGL
+ lacks the variable qualifiers \c{highp}, \c{mediump}, and \c{lowp}.
+
+ The QGLShaderProgram class makes the process of writing portable shaders
+ easier by prefixing all shader programs with the following lines on
+ desktop OpenGL:
+
+ \code
+ #define highp
+ #define mediump
+ #define lowp
+ \endcode
+
+ This makes it possible to run most GLSL/ES shader programs
+ on desktop systems. The programmer should restrict themselves
+ to just features that are present in GLSL/ES, and avoid
+ standard variable names that only work on the desktop.
+
+ \section1 Simple shader example
+
+ \code
+ program.addShader(QGLShader::VertexShader,
+ "attribute highp vec4 vertex;\n"
+ "attribute mediump mat4 matrix;\n"
+ "void main(void)\n"
+ "{\n"
+ " gl_Position = matrix * vertex;\n"
+ "}");
+ program.addShader(QGLShader::FragmentShader,
+ "uniform mediump vec4 color;\n"
+ "void main(void)\n"
+ "{\n"
+ " gl_FragColor = color;\n"
+ "}");
+ program.link();
+ program.enable();
+
+ int vertexLocation = program.attributeLocation("vertex");
+ int matrixLocation = program.attributeLocation("matrix");
+ int colorLocation = program.uniformLocation("color");
+ \endcode
+
+ With the above shader program active, we can draw a green triangle
+ as follows:
+
+ \code
+ static GLfloat const triangleVertices[] = {

+ \section1 Partial shaders
+
+ Desktop GLSL can attach an arbitrary number of vertex and fragment
+ shaders to a shader program. Embedded GLSL/ES on the other hand
+ supports only a single shader of each type on a shader program.
+
+ Multiple shaders of the same type can be useful when large libraries
+ of shaders are needed. Common functions can be factored out into
+ library shaders that can be reused in multiple shader programs.
+
+ To support this use of shaders, the application programmer can
+ create shaders with the QGLShader::PartialVertexShader and
+ QGLShader::PartialFragmentShader types. These types direct
+ QGLShader and QGLShaderProgram to delay shader compilation until
+ link time.
+
+ When link() is called, the sources for the partial shaders are
+ concatenated, and a single vertex or fragment shader is compiled
+ and linked into the shader program.
+
+ It is more efficient to use the QGLShader::VertexShader and
+ QGLShader::FragmentShader when there is only one shader of that
+ type in the program.
