Issues for collision against curved surfaces:
|
||||
|
||||
Surface edges need to be handled differently than surface planes
|
||||
|
||||
Plane expansion causes raw surfaces to expand past expanded bounding box
|
||||
|
||||
Position test of a volume against a surface is tricky.
|
||||
|
||||
Position test of a point against a surface is not well defined, because the surface has no volume.
|
||||
|
||||
|
||||
Tracing leading edge points instead of volumes?
|
||||
Position test by tracing corner to corner? (8*7 traces -- ouch)
|
||||
|
||||
coplanar edges
|
||||
triangulated patches
|
||||
degenerate patches
