(WIP) Supermodel WIP - Supermodel - 模擬器

2011.07.06

I finally found a few hours to play with Supermodel these past few days.
[krom] submitted a patch adding a few ROM sets. Dirt Devils appears to
be playable, albeit with encrypted 2D graphics and also some unusual 3D
glitches, namely inverted polygon normals on the left wheels of the
vehicles. Spikeout was also easy to get up and running but something
is preventing it from entering the game.

Dirt Devils

finally got around to hooking up a feature I had worked out months ago
in my standalone prototype renderer: texture offsets. Virtual On:
Oratorio Tangram makes extensive use of them, which is why the bots
never looked quite right. They are also cleverly employed by Scud Race
and Daytona USA 2 during the vehicle selection screens to apply
different texture maps without updating polygon vertices.

Unfortunately, texture offsets are not yet ready for prime time and
likely will remain disabled in the next release. They are not
compatible with Supermodel's texture and model caching systems, and
actually cause more problems than they solve. Eventually, I intend
to rewrite the entire 3D engine but before embarking on such a
time-consuming overhaul, I need to uncover more of the Real3D's
secrets.

Virtual On before (left) and after (right) texture offsets have been
applied.

With texture offsets enabled, the vehicle selection screens in Scud
Race and Daytona USA 2 look correct.
