Detailed Description

The SoLightModel class is a node for specifying the model for geometry lighting.

Use nodes of this type to set up how lighting should affect subsequent geometry in the scene.

FILE FORMAT/DEFAULTS:

    LightModel {
        model PHONG
    }

Member Enumeration Documentation

Enumerates available light models.

Enumerator:
BASE_COLOR 

Use the current diffuse material color for subsequent geometry, and do not let any lightsources influence the appearance of the rendering primitives.

PHONG 

Use Phong-style shading for the geometry.


Constructor & Destructor Documentation

SoLightModel::SoLightModel ( void  )

Constructor.

References BASE_COLOR, model, and PHONG.

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

Destructor.


Member Function Documentation

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

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

Reimplemented from SoNode.

References SoOverrideElement::getLightModelOverride(), SoAction::getState(), SoField::isIgnored(), SoNode::isOverride(), model, and SoOverrideElement::setLightModelOverride().

Referenced by callback(), and GLRender().

void SoLightModel::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.

References doAction().

void SoLightModel::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.

References doAction().


Member Data Documentation

Lightmodel to use. Defaults to SoLightModel::PHONG.
