Some interesting Sega Dreamcast science I've been doing on the side recently... Here's a direct hardware capture of a tech demo of Bruce's aptly-named "Dreamcast Mesh Shit," featuring assets from... Uhhh... I don't even know where he jacked these from... 😂 ANYWAY, the main thing I've been working on is optimizing the skinning for the animations using my SH4ZAM fast math and linear algebra library, which can easily become one of the primary bottlenecks when running the late 6th generation games on the Dreamcast. My work has been mostly to allow the vast majority of the skinning math to occur in the SH4's XMTRX back-bank of floating-point registers, rather than having to round-trip to and from memory for every operation... Just shaved off a few hundred microseconds per mesh this way, with a lot more room to go. Once I have this stuff SOLID, I plan to bring it back to our DC port of Grand Theft Auto: Vice City, where skinning was one of the major contributors to FPS dips.

pretty sure matt + jay wouldn't approve of this. might be worth an email to zapruder
