Detailed Description

The SoVertexShader class is used for setting up vertex shader programs.

See Shaders in Coin for more information on how to set up a scene graph with shaders.

FILE FORMAT/DEFAULTS: 

    VertexShader {
      isActive TRUE
      sourceType FILENAME
      sourceProgram ''
      parameter []
    }

Member Function Documentation

SoType SoVertexShader::getClassTypeId (void) [static]

This static method returns the SoType object associated with objects of this class.

Reimplemented from SoShaderObject.

SoType SoVertexShader::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 ** SoVertexShader::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.

Reimplemented from SoShaderObject.

const SoFieldData * SoVertexShader::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.

void SoVertexShader::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.

SbBool SoVertexShader::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.
