Member Function Documentation

void EggLoader::make_polyset ( EggBin *  egg_bin,
PandaNode *  parent,
const LMatrix4d *  transform,
bool  is_dynamic,
CharacterMaker *  character_maker 
)

Creates a polyset--that is, a Geom--from the primitives that have already been grouped into a bin.

If transform is non-NULL, it represents the transform to apply to the vertices (instead of the default transform based on the bin's position within the hierarchy).

void EggLoader::reparent_decals ( )

For each node representing a decal base geometry (i.e.

a node corresponding to an EggGroup with the decal flag set), move all of its nested geometry directly below the GeomNode representing the group.

void EggLoader::start_sequences ( )

Starts all of the SequenceNodes we created looping.

We have to wait until the entire graph is built up to do this, because the SequenceNode needs its full set of children before it can know how many frames to loop.
