Detailed Description

manages level-of-detail

Constructor & Destructor Documentation

Parameters

group_name Only useful for getGroupName()

Adds a node associated with a level of detail.

Parameters

level	Distance (number of units) from which this level of detail kicks in
node	The node to show at this level
reparent	If true, node will be removed from its current parent first

void LODNode::forceLevelOfDetail ( int n )

Forces the level of detail to be n.

If n>number of levels, the most detailed level is used. This is used to disable LOD when the end camera is activated, since it zooms in to the kart.

void LODNode::OnAnimate ( u32 timeMs )

virtual

OnAnimate() is called just before rendering the whole scene.

This method will be called once per frame, independent of whether the scene node is visible or not.

int LODNode::m_forced_lod

private

The normal level of detail can be overwritten.

If m_forced_lod is >=0, only this level is be used.
