Detailed Description

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

The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium:

  Material {
    exposedField SFFloat ambientIntensity  0.2         # [0,1]
    exposedField SFColor diffuseColor      0.8 0.8 0.8 # [0,1]
    exposedField SFColor emissiveColor     0 0 0       # [0,1]
    exposedField SFFloat shininess         0.2         # [0,1]
    exposedField SFColor specularColor     0 0 0       # [0,1]
    exposedField SFFloat transparency      0           # [0,1]
  }
  

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/technicalinfo/specifications/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:

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.


Member Data Documentation

SoSFColor SoVRMLMaterial::diffuseColor
 

The diffuse color component. Default value is (0.8, 0.8, 0.8).

SoSFFloat SoVRMLMaterial::ambientIntensity
 

The ambient intensity. Default value is 0.2.

SoSFColor SoVRMLMaterial::specularColor
 

The specular color component. Default value is (0, 0, 0).

SoSFColor SoVRMLMaterial::emissiveColor
 

The emissive color component. Default value is (0, 0, 0).

SoSFFloat SoVRMLMaterial::shininess
 

The shininess value. A number between 0 and 1. Default value is 0.2.

SoSFFloat SoVRMLMaterial::transparency
 

The material transparency. Valid range is from 0.0 (completely opaque) to 1.0 (completely transparent). Default value is 0.0.
