<h2>Detailed Description</h2>
<p>The QGLShaderProgram class allows OpenGL shader programs to be linked and used.</p>
<a name="introduction"></a>
<h3>Introduction</h3>
<p>This class supports shader programs written in the OpenGL Shading Language (GLSL) and in the OpenGL/ES Shading Language (GLSL/ES).</p>
<p><a href="qglshader.html">QGLShader</a> and QGLShaderProgram shelter the programmer from the details of compiling and linking vertex and fragment shaders.</p>
<p>The following example creates a vertex shader program using the supplied source <tt>code</tt>. Once compiled and linked, the shader program is activated in the current <a href="qglcontext.html">QGLContext</a> by calling <a href="qglshaderprogram.html#bind">QGLShaderProgram::bind</a>():</p>
<pre> QGLShader shader(QGLShader::Vertex);
shader.compileSourceCode(code);
QGLShaderProgram program(context);
program.addShader(shader);
program.link();
program.bind();</pre>
<a name="writing-portable-shaders"></a>
<h3>Writing portable shaders</h3>
<p>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: <tt>gl_Vertex</tt>, <tt>gl_Normal</tt>, <tt>gl_Color</tt>, and so on. Desktop OpenGL lacks the variable qualifiers <tt>highp</tt>, <tt>mediump</tt>, and <tt>lowp</tt>.</p>
<p>The QGLShaderProgram class makes the process of writing portable shaders easier by prefixing all shader programs with the following lines on desktop OpenGL:</p>
<pre> #define highp
#define mediump
#define lowp</pre>
<p>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.</p>
<a name="simple-shader-example"></a>
<h3>Simple shader example</h3>
<pre> 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();
int vertexLocation = program.attributeLocation("vertex");
int matrixLocation = program.attributeLocation("matrix");
int colorLocation = program.uniformLocation("color");</pre>
<p>With the above shader program active, we can draw a green triangle as follows:</p>
<pre> static GLfloat const triangleVertices[] = {
60.0f, 10.0f, 0.0f,
110.0f, 110.0f, 0.0f,
10.0f, 110.0f, 0.0f
};
QColor color(0, 255, 0, 255);
QMatrix4x4 pmvMatrix;
pmvMatrix.ortho(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);</pre>
<a name="binary-shaders-and-programs"></a>
<h3>Binary shaders and programs</h3>
<p>Binary shaders may be specified using <tt>glShaderBinary()</tt> on the return value from <a href="qglshader.html#shaderId">QGLShader::shaderId</a>(). The <a href="qglshader.html">QGLShader</a> instance containing the binary can then be added to the shader program with <a href="qglshaderprogram.html#addShader">addShader</a>() and linked in the usual fashion with <a href="qglshaderprogram.html#link">link</a>().</p>
<p>Binary programs may be specified using <tt>glProgramBinaryOES()</tt> on the return value from <a href="qglshaderprogram.html#programId">programId</a>(). Then the application should call <a href="qglshaderprogram.html#link">link</a>(), which will notice that the program has already been specified and linked, allowing other operations to be performed on the shader program.</p>
