Detailed DescriptionThe 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

---

enum SoLightModel::ModelEnumerates 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​.

Member Function Documentation

SoType SoLightModel::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 } else if (node->getTypeId()​.isOfType(SoGroup::getClassTypeId())) { SoGroup * group = (SoGroup *)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​. Implements SoBase​.

---

const SoFieldData * SoLightModel::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 SoFieldContainer​.

---

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()​.
