Detailed Description¶

The PySide.QtOpenGL.QGLShaderProgram class allows OpenGL shader programs to be linked and used.

Introduction¶

This class supports shader programs written in the OpenGL Shading Language (GLSL) and in the OpenGL/ES Shading Language (GLSL/ES).

PySide.QtOpenGL.QGLShader and PySide.QtOpenGL.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 code . Once compiled and linked, the shader program is activated in the current PySide.QtOpenGL.QGLContext by calling QGLShaderProgram.bind() :
shader = QGLShader(QGLShader.Vertex)
shader.compileSourceCode(code)

program = QGLShaderProgram(context)
program.addShader(shader)
program.link()

program.bind()

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: gl_Vertex , gl_Normal , gl_Color , and so on. Desktop OpenGL lacks the variable qualifiers highp , mediump , and lowp .

The PySide.QtOpenGL.QGLShaderProgram class makes the process of writing portable shaders easier by prefixing all shader programs with the following lines on desktop OpenGL:
#define highp
#define mediump
#define lowp
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.

Simple shader example¶

program.addShaderFromSourceCode(QGLShader.Vertex,
    "attribute highp vec4 vertex\n" \
    "attribute mediump mat4 matrix\n" \
    "void main(void)\n" \
    "{\n" \
    "   gl_Position = matrix * vertex\n" \
    "}")
program.addShaderFromSourceCode(QGLShader.Fragment,
    "uniform mediump vec4 color\n" \
    "void main(void)\n" \
    "{\n" \
    "   gl_FragColor = color\n" \
    "}")
program.link()
program.bind()

vertexLocation = program.attributeLocation("vertex")
matrixLocation = program.attributeLocation("matrix")
colorLocation = program.uniformLocation("color")

With the above shader program active, we can draw a green triangle as follows:

triangleVertices = (
    60.0f,  10.0f,  0.0f,
    110.0f, 110.0f, 0.0f,
    10.0f,  110.0f, 0.0f)

color = QColor(0, 255, 0, 255)

pmvMatrix = QMatrix4x4()
pmvMatrix.ortho(self.rect())

program.enableAttributeArray(vertexLocation)
program.setAttributeArray(vertexLocation, triangleVertices, 3)
program.setUniformValue(matrixLocation, pmvMatrix)
program.setUniformValue(colorLocation, color)

glDrawArrays(GL_TRIANGLES, 0, 3)

program.disableAttributeArray(vertexLocation)

Binary shaders and programs¶

Binary shaders may be specified using glShaderBinary() on the return value from QGLShader.shaderId() . The PySide.QtOpenGL.QGLShader instance containing the binary can then be added to the shader program with PySide.QtOpenGL.QGLShaderProgram.addShader() and linked in the usual fashion with PySide.QtOpenGL.QGLShaderProgram.link() .

Binary programs may be specified using glProgramBinaryOES() on the return value from PySide.QtOpenGL.QGLShaderProgram.programId() . Then the application should call PySide.QtOpenGL.QGLShaderProgram.link() , which will notice that the program has already been specified and linked, allowing other operations to be performed on the shader program.
