almost all of what you said is true. true GPUs today is depended on pipelines, because pipelines is a efficient way to process video/image data. true the bits method went the way of the dinosaurs and it doesnt matter now as it did with the era of older console like sega genesis, super...

Anybody else with any useful infomation? anybody? please help.

i know what the fill rate means and the theoretical fill rate of the vdp 1 (400,000 per 1/60sec). reading the documents is what got me asking the questings in the first place. but the thought put (how many bits the processor process at a time) can put the gpu at just as much of an advantage as...

I dont know if anyone else ask this but is the vdp1 32bits? base on documentation i know the vdp2 is 32bits but everything i see on the vdp1 suggest that it is 16bits can anybody please clear this up for me?

sorry for taking so long but i like to say about two weeks of your first response i did some research and found ya'll was right, the vdp 1 is a 2d chip, i was a bit too busy at the time to respond. I also have a playstation one development manual to compare the two consoles. i like to say...

I like to get WinterSports Eins again, it's not on this site any more or the link is broken. but wintersports use 2d sprites it's 3d is prerendered.

the psx can't do 3d either? saturn has gourad shading made hardware, that seems to be a clue of 3d hardware. if it dont process any z positioning how it render shawdows calculations like it do? also how do it process the normals (polygons face) data? as for it not having a z-buffer that...

a question that i had for years after i first read the vdp 1 manual, is how do the saturn do 3d (x,y,z and face normals)? i only see 2d hardware function in the manual (the vdp 1 user manual) yet the SGL and SBL show 3d vertices and face normals like in other 3d hardware. what do this mean...

thanks everybody you be a great help.

i kind of figure it couldn't, but what i want to do is find a way to scale picture data from one source like the vram cart to the vdp1, being how the vdp1 read and ignore data base on scale setting, i was hoping it could read from another ram source other then it's own to save me the hard...

i plan on making a new game, but to be honest i dont know what to to decide on, maybe a 3d fighter. im doing a little saturn 3d modeling right now (i'll post up some of my work you'll be please) and is trying to get the hang of vertice animation. but that's not the point (i was just letting...

i think this is done with color shadow and the k-coeficient table.

does anybody knows how to use the dsp chip in scu? has anybody tried to use it? i like to use it for light/shading and preclipping. i read where the dsp can do light calculation but can anyone tell me how the dsp do lighting calculation? a mthpolytransparm table is listed in the program...

i read those soa tutorial notes and the SCU manual on the dsp, even the (SBL) basic library manual. but can you tell me about how to use the dsp in light calculation? does it do gourad shading? I think i can make a supreb engine if i can program the dsp to do lighting (gourad shading) and...

yeah, in that case i have to find a way to cope with that fact. im learning alot about the saturn (no more coding contests?). sometime around this december im buying a new modchip, these emulators is not cutting it. maybe that's it about the b-bus for now. being how it's structure a...

no, at least not much unless there's any slow down when acessing vdp 1 and 2 vram at the same time and will it add more stress if i use the dsp to do vertice transformation math. if i like to use 3 or 4 resources (sh2,vdp 1 and 2 the scu's dsp) will there be a issue?

well i kind of figure that but if that's the case is there another way around the b-bus? do any other buses go to the vdp 1 and 2? like the the system bus?

oh no,that's not really what i wanted to ask, i know i ask it but, it's like this, what if i wanted to do some sort of 3d transfomation that require 32bit vertices animation using the b-bus at full 28mhz speed (with 60 frames per second)? in other words a better way to put it, what if a...

the sh2 system bus runs at 32bits while the b bus runs at 16bits(multiplexed). wouldn't that be a problem in transmitting 32bit data from sh2 to either vdp 1 or 2? what would happen if you try? is there any way to over come this? I hope i'm looking at it wrong.

thanks it works perfectly now be sure to see some great games soon.
