Sculpted Prims: Importing
Revision as of 01:45, 26 June 2007 by Strife Onizuka (talk | contribs)
Currently there is a push to get the client to import models as sculpted prims from a variety of 3d modeling formats.
• | 3dm | – | VWR-858 | Rhino & MoI |
• | 3ds | – | VWR-1111 | 3D Studio Max |
• | obj | – | VWR-1110 | Wavefront |
The main method currently for doing this translation is to use UV mapping cordinants to retrieve positions on the surface of the mesh. There are three hurdles to this.
- UV mappings may be missing or not continuous.
- The objects may be made up of multiple surfaces.
- Distributing the limited LOD appropriately.
- Stitching surfaces together. The UV mapping along the edges may not align.
The correct approach to this is to refactor the mesh and UV coordinates into a single surface. To stitch two mesh together without complex math, the derivatives of the UV coordinates need to match on each side of edge.
