Detailed Description
The SoCacheHint class is a node containing hints about how to cache geometry.
The SoCacheHint node is used to set up clues to the rendering subsystem about how Coin should cache vertex data.
Please note that this is an experimental class. The API might change a lot before/if it's included in any official Coin release.
FILE FORMAT/DEFAULTS:
CacheHint { memValue 0.5 gfxValue 0.5 }

Member Function Documentation
void SoCacheHint::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 SoCacheHint::doAction (SoAction * action) [virtual]This function performs the typical operation of a node for any action.
Reimplemented from SoNode.
void SoCacheHint::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 SoCacheHint::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.
void SoCacheHint::getBoundingBox (SoGetBoundingBoxAction * action) [virtual]Action method for the SoGetBoundingBoxAction.
Calculates bounding box and center coordinates for node and modifies the values of the action to encompass the bounding box for this node and to shift the center point for the scene more towards the one for this node.
Nodes influencing how geometry nodes calculates their bounding box also overrides this method to change the relevant state variables.
Reimplemented from SoNode.
void SoCacheHint::pick (SoPickAction * action) [virtual]Action method for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoNode.
