NAME¶

SoFragmentShader - The SoFragmentShader class is used for setting up fragment shader programs. See Shaders in Coin for more information on how to set up a scene graph with shaders.

SYNOPSIS¶

#include <Inventor/nodes/SoFragmentShader.h> Inherits SoShaderObject.

Public Member Functions¶

virtual SoType getTypeId (void) const Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting. SoFragmentShader (void) virtual ~SoFragmentShader ()

Static Public Member Functions¶

static SoType getClassTypeId (void) static void initClass (void) static SbBool isSupported (SourceType sourceType)

Protected Member Functions¶

virtual const SoFieldData * getFieldData (void) const

Static Protected Member Functions¶

static const SoFieldData ** getFieldDataPtr (void)

Additional Inherited Members¶

Member Function Documentation¶

SoType SoFragmentShader::getTypeId (void) const [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:

void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}

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.

const SoFieldData * SoFragmentShader::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 SoShaderObject.

SbBool SoFragmentShader::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.
