The SoGeometryShader class is used for loading geometry shader programs.

FILE FORMAT/DEFAULTS:
GeometryShader { isActive TRUE sourceType FILENAME sourceProgram "" parameter [] inputType TRIANGLES_IN outputType TRIANGLE_STRIP_OUT maxEmit 8 }
SoGeometryShader::SoGeometryShader | ( | void | ) |
Constructor.
References inputType, LINE_STRIP_OUT, LINES_IN, maxEmit, outputType, POINTS_IN, POINTS_OUT, and TRIANGLES_IN.
SoGeometryShader::~SoGeometryShader | ( | ) | [virtual] |
Destructor.
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.
References SoShaderObject::ARB_PROGRAM, SoShaderObject::CG_PROGRAM, and SoShaderObject::GLSL_PROGRAM.
The type of geometry used as input to the shader. Default value is TRIANGLES_IN.
Referenced by GLRender(), and SoGeometryShader().
The type of geometry generated from the shader. Default value is TRIANGLE_FAN_OUT.
Referenced by GLRender(), and SoGeometryShader().
The maximum number of vertices emitted from the shader. Default value is 8. This corresponds to the GL_GEOMETRY_VERTICES_OUT_EXT enum.
Referenced by GLRender(), and SoGeometryShader().
