Ripping models?
Posted: Mon Nov 13, 2023 6:36 pm
Hello. I was wondering if it was possible to rip 3d models from the emulator? If so, how?
I was told by Bart since I asked him the similar question
Here's his quote
"These games use custom formats. There are no tools. Most 3D assets are stored in VROM directly as Real3D-formatted polygon lists. Unfortunately there is no great way to determine where models begin but IIRC there is a flag for the last polygon in the list. Texture maps are stored separately. Some games are well-behaved in how they lay textures out in texture RAM, so you could probably write an exporter that converts a model to OBJ format and then dump the run-time texture image and use that with the texture coordinates in the model. Other games do weird stuff that could make this painful.
The Scud Race and Daytona 2 player vehicle models are not stored in VROM and are loaded dynamically into polygon RAM because they are deformable."
