there is different ways to solve or optimize this "problem". for example Naomi2's ELAN use 2 matrices, one 4x4 for vertex transformation and one more 3x3 for normals. as of lighting - sorry, in prev-prev message I've used wrong wording, I don't believe hikaru had per-fragment Phong in mode...

I agree that Hikaru is almost certainly not performing the full Phong shading calculations for each pixel, given how expensive they are. That being said, in this video of Planet Harriers running on real hardware, the specular highlights on the flying vehicle at 0:41 and the joystick during the &quo...

I'm certain it has per pixel lighting. Look at the specular highlight, that is simply not possible unless the geometry is highly tessellated, which it isn't because you can see an identical model on the right side which I've traced out in red. geometry looks like that, about 55K vertices per scene ...

Feature wise it's not really that complex, limited texture types supported, probably very limited actual rendering modes supported, but it has great support for lighting. I was a little skeptical that it was actually doing per pixel lighting, I mean you can sort of fake it just by tessellating geom...

What doesn't make sense to me is Hikaru's graphics chips running at only 41.6 MHz when the "less powerful" NAOMI/Dreamcast runs its PowerVR2 chip at 100MHz, nor Model 3's graphics chips running at only 33 MHz when the Model 2 runs at 50 MHz. the main problem of HOLLY chipset is lack of ha...

anyway, all these talks about clock and speeds went too far. all I'm actually wanted to say is: if assume what Hikaru's GPU really is Real3D's product, it looks like a not big evolution improvement compared to Model 3 video board - - a bit faster clock - 41MHz instead of 33MHz - a bit improved textu...

The point is that if a GPU has a theoretical fillrate, if it renders nothing but tiny polygons it is not going to even come close to that theoretical figure, even taking T&L out of the equation. Voodoo 1 can theoretically render up to 50 megapixels/s but only up to 1.9 million 10-pixel polygons...

no 3D renderer is 100% efficient in terms of fillrate (except perhaps PowerVR which uses a very different implementation). all the modern GPUs uses various HSR optimizations, and they are (almost) same efficient in this as old good PowerVR 2 ;) I doubt that Sega would have accepted a fillrate of 33...

Model 3 performs hidden surface removal using the z-buffer; here's a link to the Pro-1000 product description , look for "hidden surface removal" on page 21. The way it works is that Earth sends the 1/z value of each pixel to be rendered to the depth buffer 3D-RAM and if there are no othe...

I'm skeptical that most of the Hikaru video ASICs actually run at only 41.6 MHz. For a start, at that speed why would they even need heatsinks? Also, if "Europe"'s SDRAM is clocked at 83.3 MHz then surely "Europe" itself would have to be running that fast in order to use it. Per...
