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.
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.
The diffuse color component. Default value is (0.8, 0.8, 0.8).
The ambient intensity. Default value is 0.2.
The specular color component. Default value is (0, 0, 0).
The emissive color component. Default value is (0, 0, 0).
The shininess value. A number between 0 and 1. Default value is 0.2.
The material transparency. Valid range is from 0.0 (completely opaque) to 1.0 (completely transparent). Default value is 0.0.
