GLSL Shader.
<p>
<a class="el" href="a00645.html" title="GLSL Shader.">vtkGLSLShader</a> is a concrete class that creates and compiles hardware shaders written in the OpenGL Shadering Language (GLSL, OpenGL2.0). While step linking a vertex and a fragment shader is performed by <a class="el" href="a00648.html" title="GLSL Shader Program.">vtkGLSLShaderProgram</a>, all shader parameters are initialized in this class.<p>
