FILE FORMAT/DEFAULTS:
SoGeometryShader::SoGeometryShader | ( | void | ) |
Constructor.
|
virtual |
Destructor.
|
static |
This static method returns the SoType object associated with objects of this class.
Reimplemented from SoShaderObject.
|
virtual |
Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting.
Usage example:
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.
For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.
Reimplemented from SoShaderObject.
|
staticprotected |
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Reimplemented from SoShaderObject.
|
protectedvirtual |
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL
.
Reimplemented from SoShaderObject.
|
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.
|
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.
|
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.
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.
