Re: Model 3 Step 1/1.5 and Step 2 Video Board Differences
I don't know if Pro-1000 operates in passes per se but there is this concept of a contour texture. Alpha blending also works entirely differently than expected. One theory is that it actually renders only every other pixel and then biases the rendered pixels toward visible or black. See here . quit...

Re: Model 3 Step 1/1.5 and Step 2 Video Board Differences
We know the gist of how it works and some details are hinted at in patents. By piecing together what the games are doing, what the official (very high level) documentation says, and hints from the Real3D SDK, more is known. For example, Ian and Matthew recently deduced that part of the Real3D culli...

I'm working on a block diagram to show how the Model 3 video board ASICs are linked together, but suffice to say that it is not the same as Hikaru. well, to me it looks similar to some degree for example 2 texture bank "Australia" ASICs (2 rightmost at diagram) - each have inside 4MB of R...

Re: Model 3 Step 1/1.5 and Step 2 Video Board Differences
and the board schematics for Step 2 (I took from the well-known thread in this forum): https://supermodel3.com/ArchivedForum/i.imgur.com/9ahGne3.jpg a bit off topic, but anyway - here is block diagram of Sega Hikaru video system. how do you think, is it looks similar to Real3D 100 / Model 3 ? IMO i...
