Member Enumeration Documentation
enum SoGeometryShader::InputTypeEnumerates the input types.
Enumerator:
- POINTS_IN
- Shader uses points as input.
- LINES_IN
- Shader uses lines as input.
- TRIANGLES_IN
- Shader uses triangles as input. OpenGL will automatically convert quads and polygons into triangles.
enum SoGeometryShader::OutputTypeEnumerates the output types.
Enumerator:
- POINTS_OUT
- Shader generates points.
- LINE_STRIP_OUT
- Shader generates line strips.
Constructor & Destructor Documentation
SoGeometryShader::SoGeometryShader (void)Constructor.
References inputType, LINE_STRIP_OUT, LINES_IN, maxEmit, outputType, POINTS_IN, POINTS_OUT, and TRIANGLES_IN.
SoGeometryShader::~SoGeometryShader () [virtual]Destructor.
Member Function Documentation
void SoGeometryShader::initClass (void) [static]Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
Reimplemented from SoShaderObject.
void SoGeometryShader::GLRender (SoGLRenderAction * action) [virtual]Action method for the SoGLRenderAction.
This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.
Reimplemented from SoShaderObject.
References SoFieldContainer::get(), SoAction::getState(), SoShaderObject::GLRender(), inputType, SoShaderObject::isActive, LINE_STRIP_OUT, LINES_IN, maxEmit, outputType, POINTS_IN, POINTS_OUT, SoDebugError::post(), and TRIANGLES_IN.
SbBool SoGeometryShader::isSupported (SourceType sourceType) [static]Returns a boolean indicating whether the requested source type is supported by the OpenGL driver or not.
Beware: To get a correct answer, a valid OpenGL context must be available.
