See Shaders in Coin for more information on how to set up a scene graph with shaders. See also SoShaderProgram Member Enumeration Documentation enum SoShaderObject::SourceType Used for enumerating the shader types in sourceProgram. Enumerator ARB_PROGRAM Specifies an ARB shader. CG_PROGRAM Specifies a Cg shader program. GLSL_PROGRAM Specifies a GLSL program. FILENAME Shader should be loaded from the file in sourceProgram. Constructor & Destructor Documentation SoShaderObject::SoShaderObject (void) [protected] Constructor. SoShaderObject::~SoShaderObject () [protected], [virtual] Destructor Member Function Documentation SoType SoShaderObject::getClassTypeId (void) [static] This static method returns the SoType object associated with objects of this class. SoType SoShaderObject::getTypeId (void) const [virtual] Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and 'downward' casting. Implements SoBase. Reimplemented in SoFragmentShader, SoGeometryShader, and SoVertexShader. const SoFieldData ** SoShaderObject::getFieldDataPtr (void) [static], [protected] This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Returns the SoFieldData class which holds information about fields in this node. const SoFieldData * SoShaderObject::getFieldData (void) const [protected], [virtual] Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL. Reimplemented from SoFieldContainer. Reimplemented in SoFragmentShader, SoGeometryShader, and SoVertexShader. void SoShaderObject::GLRender (SoGLRenderAction * action) [virtual] Action method for the SoGLRenderAction. This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method. Reimplemented from SoNode. Reimplemented in SoGeometryShader. void SoShaderObject::search (SoSearchAction * action) [virtual] Action method for SoSearchAction. Compares the search criteria from the action to see if this node is a match. Searching is done by matching up all criteria set up in the SoSearchAction -- if any of the requested criteria is a miss, the search is not deemed successful for the node. See also SoSearchAction Reimplemented from SoNode. void SoShaderObject::updateParameters (SoState * state) Used internally to update shader parameters. SoShaderObject::SourceType SoShaderObject::getSourceType (void) const Returns the shader type detected in source program. SbString SoShaderObject::getSourceProgram (void) const Returns the actual shader program. SbBool SoShaderObject::readInstance (SoInput * in, unsigned short flags) [protected], [virtual] This method is mainly intended for internal use during file import operations. It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistent representation of an instance of this class type. TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went OK or not. The import process should be robust and handle corrupted input streams by returning FALSE. flags is used internally during binary import when reading user extension nodes, group nodes or engines. Reimplemented from SoNode. Member Data Documentation SoSFBool SoShaderObject::isActive Enabled/disables the shader. Default value is TRUE. SoSFEnum SoShaderObject::sourceType The type of shader. SoSFString SoShaderObject::sourceProgram The shader program, or a file name if the shader should be loaded from a file. If the shader is loaded from a file, the shader type is identified by the file extension. .glsl for GLSL shaders, .cg for Cg shaders, and .vp and .fp for ARB shaders. SoMFNode SoShaderObject::parameter The shader program parameters. Author Generated automatically by Doxygen for Coin from the source code. Version 4.0.2 Tue Dec 26 2023 17:59:22 SoShaderObject(3)
