The SoShaderObject class is the superclass for all shader classes in Coin.
See Shaders in Coin for more information on how to set up a scene graph with shaders.
SoShaderObject::SoShaderObject | ( | void | ) | [protected] |
Constructor.
References ARB_PROGRAM, CG_PROGRAM, FILENAME, GLSL_PROGRAM, isActive, parameter, SoField::setDefault(), SoMField::setNum(), sourceProgram, and sourceType.
SoShaderObject::~SoShaderObject | ( | ) | [protected, virtual] |
Destructor
void SoShaderObject::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 SoNode.
Reimplemented in SoVertexShader, SoFragmentShader, and SoGeometryShader.
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 who wants to throw geometry primitives at OpenGL overrides this method.
Reimplemented from SoNode.
Reimplemented in SoGeometryShader.
Referenced by SoGeometryShader::GLRender().
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.
Reimplemented from SoNode.
References SoMField::getNum(), SoAction::getPathCode(), SoSearchAction::isFound(), parameter, SoAction::popCurPath(), SoAction::pushCurPath(), and SoNode::search().
void SoShaderObject::updateParameters | ( | SoState * | state | ) |
Used internally to update shader paramters.
References SoFieldContainer::get().
SoShaderObject::SourceType SoShaderObject::getSourceType | ( | void | ) | const |
Returns the shader type detected in sourceProgram.
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 / persistant 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.
References SoInput::getDirectories(), and SoNode::readInstance().
Enabled/disables the shader. Default value is TRUE.
Referenced by SoGeometryShader::GLRender(), and SoShaderObject().
The type of shader.
Referenced by SoShaderObject().
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.
Referenced by SoShaderObject().
The shader program parameters.
