Detailed Description

The SoVRMLMaterial class is used to assign a material to geometry.

The Material node specifies surface material properties for associated geometry nodes and is used by the VRML lighting equations during rendering. Subclause 4.14, Lighting model (<http://www.web3d.org/x3d/specifications/vrml/ISO-IEC-14772-VRML97/part1/concepts.html#4.14>), contains a detailed description of the VRML lighting model equations. All of the fields in the Material node range from 0.0 to 1.0. The fields in the Material node determine how light reflects off an object to create colour:

SoVRMLMaterial::SoVRMLMaterial ( void  )

Constructor.

SoVRMLMaterial::~SoVRMLMaterial ( ) [protected, virtual]

Destructor.


Member Function Documentation

void SoVRMLMaterial::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.

void SoVRMLMaterial::doAction ( SoAction action) [virtual]

This function performs the typical operation of a node for any action.

Reimplemented from SoNode.

void SoVRMLMaterial::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.

void SoVRMLMaterial::callback ( SoCallbackAction action) [virtual]

Action method for SoCallbackAction.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.

Reimplemented from SoNode.
