Efectivamente Scud Race / Super GT es una de las demos técnicas del R2 SDK. Precisamente hoy ojeando una vieja Sega Saturn Magazine he releído un artículo al respecto, en el que comentan las impresiones acerca de las demos de la web Game-Online:
"I don't work for Sega, but I got a chance to take a good look at Sega's new machine. The unit I saw was a PCI card inside a Pentium computer. I saw five different demos. The first demo was a 3D rotating Sega logo. It was basically liquid metal of the logo changing into different colors. Looks 100 times better of the liquid metal Sonic head I saw on the Saturn."
" Next was Temjin from Virtual On. Temjin doing his slashing move with his sword. There was a liquid metal version and full texture map version."
"Next was what Sega call the fish demo. It was a colorful fish with feet riding on some type of water bike moving only up and down in the middle of a pond. The transparent effect on the rippling waves was beautiful, better then on the N64. Then the lighting was change from daylight to just one light globe. The globe lit a small area. So as the globe move around in the pond, only part of the water and fish are shown. Then it was change to a spot light, again the spot light was moving around the pond. The beam of the light lightly lit objects behind it and with the small circular spot brightly lit whatever it hits."
"The last demo was of Super GT. First part of the demo was just the first city track. No cars to race with. The camera just move continuously around the track. The camera could be pan 360 degree around as it goes around the track. When the camera was moving on a straight part of the race track, you can see pop up far way off. Of course, that could easily hidden with some fog effect. The glass house part of the track was easily done, since it as like the water effect, but without the ripple of the water."
"The second part of the demo was two GT cars with a nice wax job on the straight road bridge over water. The two cars was waiving left and right. Again, first in shown in daylight, then at night with the light from the street lights on the bridge. The last part was with only the headlight of the cars. Seeing the light car behind hit the one in front as it waived back and forth was incredible."
"That kind of lighting effects use to use huge amounts of time to render, the Katana is doing it in real time. The demos were basically showing of the 3D power of the Katana. No 2D demo were shown. From the demos, the Katana can do Model 3 games and will no problems with Model 2 games."
