This node defines a fragment shader.
See SoShaderProgram for general information about using shaders and shader parameters.
See parent class SoShaderObject for details about using the inherited fields.

SoFragmentShader::SoFragmentShader | ( | ) |
Constructor.
static SoType SoFragmentShader::getClassTypeId | ( | ) | [static] |
Returns the type identifier for this class.
Reimplemented from SoShaderObject.
static unsigned int SoFragmentShader::getMaxTextureImageUnit | ( | ) | [static] |
Returns the maximum number of texture image units.
virtual ShaderType SoFragmentShader::getShaderType | ( | ) | const [inline, virtual] |
Returns the shader type.
Implements SoShaderObject.
virtual SoType SoFragmentShader::getTypeId | ( | ) | const [virtual] |
Returns the type identifier for this specific instance.
Reimplemented from SoShaderObject.
static SbBool SoFragmentShader::isSupported | ( | SoShaderObject::SourceType | sourceType, | |
SoState * | state = NULL | |||
) | [static] |
Indicates if fragment shaders in the specified language are supported by your graphics board.
When using a debug build of Open Inventor, some "no context available" warning messages may be generated. You can ignore them or see SoGLExtension for an example of using SoGLContext to avoid them.
