[Plib-users] Scaling loaded models - clipping problems

[Sam S. <sa...@sp...>]

Hi,

I'm having some difficultly scaling loaded models in SSG.  I have an model
in AC3D format that I wish to draw in various sizes about the scene.  So my
first thought is to load the model, and then stick relevant scaling
transforms above it.

a 0 0 0
0 a 0 0
0 0 a 0
0 0 0 1

to scale by a in all three axis.  But I get clipping problems when I do
this.  It appears that SSG isn't updating the bounding sphere? (I've tried
calling recalcBSphere() on the returned entity from ssgLoadAC). Am I doing
anything obviously wrong here?
