I've always been fasinated by prerendered technology. There's just this awesome 90s vibe about it, takes us back to our favoirte childhood games. One of those games for me was Resident Evil. I was talking to a friend today who happened to be in the business of ripping RE animations from ISO and other stuff. He showed me an interesting 'mask' image that left me wondering... (ripped it off using Rice Video Plugin)
Please see attached images.
Now, I don't know much about PS1 development nor its graphics API, so I don't know for sure how they implemented their illusion of depth. I'm almost certain (correct me if I'm wrong) that they didn't have programmable shaders at the time, but I guess it doesn't necessarily mean that they didn't have access to a depth buffer, if that's the case, and they used depth maps, well depth maps are greyscale images usually, which leaves me wondering what those colors mean in that 'mask' image... They definitely look like they're somehow related to depth, but why colored? Couldn't they just have used, say white and magenta?
Any idea what those colors mean?
(And if anybody know some detail about how they created illusion of depth please share)
