Member Enumeration Documentation

   enum SoGeometryShader::InputType Enumerates 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::OutputType Enumerates the output types.
       Enumerator:

       POINTS_OUT
              Shader generates points.

       LINE_STRIP_OUT
              Shader generates line strips.

Constructor & Destructor Documentation

   SoGeometryShader::SoGeometryShader (void) Constructor.
   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.

   SbBool SoGeometryShader::isSupported (SourceTypesourceType) [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.

Member Data Documentation

   SoSFEnum SoGeometryShader::inputType The type of geometry used as input to the shader. Default
       value is TRIANGLES_IN.
   SoSFEnum SoGeometryShader::outputType The type of geometry generated from the shader. Default
       value is TRIANGLE_FAN_OUT.
   SoSFInt32 SoGeometryShader::maxEmit The maximum number of vertices emitted from the shader.
       Default value is 8. This corresponds to the GL_GEOMETRY_VERTICES_OUT_EXT enum.
