Changeset 444 for cafu/trunk

Timestamp:

Author:

Message:

Fixed bugs aplenty:

• Libs: When CollisionModelStaticTs were created from degenerate mesh input as it can occur with certain forms of Bezier patches, it sometimes caused the well-formed triangles to be disregarded as well.
• CaWE: When the command history cuts the command queue due to memory constraints, it now keeps the ID of the latest deleted command that suggested saving the map file, not the one that is shown to the user.
• CaWE: Renamed MapBezierPatchT::CreateConvexEndcap() to MapBezierPatchT::CreateQuarterDisc() and much simplified its code.
• CaWE: Using the Morph tool does no longer cause a crash when Undo or Redo is used.
• Other minor tweaks.
