Amiga and VR
Once on internet I read about an amiga card for 3d,
(in the pictures there was not texture mapping) for use with vr games. The card was very expensive and not for home use. 1990-1992 year Its true or amiga fan boy inventions? |

How many more of these threads are you going to create; non Amiga lover???
...your only purpose on EAB seems to be trying to disprove anything Amiga throughout the past Tell us all again why you joined an Amiga forum because I'm confused??? Anyway, to answer your question though, there are numerous threads on EAB talking about VR and Amiga gear used in the setup... just search. ...although I'd imagine you'll believe it's all bullshit anyway so; no need for anyone to reply further. |

And I believed amiga dominated in the low end market. Also,for example I opened a thread about amiga at nasa, because I believe is possible amiga was used at nasa. I am an amiga lover. And about the amiga and the vr 3d card,it is because I believe it can be true. I opened a new thread because in the searches I did there is nothing about this card,but only about amiga 3000. |

I born in savona,in the old days,1993,I was an amiga 1200 user
and I discussed versus all amiga detractor. I had some friend on bbs,and I received at home demos and sound disk from other amiga fans. I was "Dark Soul" on the "ultimo impero bbs",and I had also various names, because to bypass the time limit I created various accounts. Here for the thread about the truth in video editing, people say that I am a troll. What do you know about the vr card for the vr systems? I found only things about the amiga 3000,not the cards. |

Texture mapping wasn't used, because even the PC struggled with it in the early 1990's. They used the Amiga A3000 and some custom hardware for about 4 years before they switched to a PC setup, but even then, the PC on its own wasn't capable enough of doing the texture mapping they needed and had to be substantially backed up with additional hardware to do the brunt of the graphics work. If its your contention that because the Amiga didn't use texture mapping so therefore it was shit, news update.... it looked shit texture mapped as well, because we're talking about the 1990's!!! Same as "interactive movies" in the 1990's, it was a fad that didn't last. And its also a matter of RECORD that NASA used the Amiga, plenty of youtube videos where they specifically talk about the Amiga and show it in action. |

I said about the texture mapping only to describe better how was the pictures of virtual reality,it was not a comment about amiga power. Quote:

Ok guys,I DONT WANT to doubt about amiga power,I want only know about this

That Virtuality service manual is very interesting, for sure!
Thanks for sharing it |

Have you actually looked up what the TM34020 coupled with a TMS34082 can do? If you had, you'd have understood that what Amiga History wrote there is 100% accurate (heck, even your ridiculous exaggeration of what they wrote is true). The TMS34020 is not just some random fixed function VGA chip, it is a full fledged graphics processor - as in, a CPU designed for doing graphics stuff. The TMS34082 is a full floating point processor specifically designed to deal with 3D stuff. They both also run really fast (40MB/sec memory bandwidth, instructions tend to take 1 cycle for the integer stuff). These chips can do very, very interesting stuff for pre-PSX tech. A few examples: - Draw lines, circles, curves (at a rate of about 5 million pixels/second) - Flood fill at (as I understand it) 40MB/sec - Transform 3D coordinates into 2D coordinates on the card, so no CPU overhead there either. These three functions by themselves are enough to do all that's claimed here. Especially when you consider the CS1000 had two of them. For reference, see: http://www.datasheetcatalog.com/data...34020-32.shtml https://books.google.nl/books?id=-4n...034082&f=false Edit: there is a much more in depth dook about the TMS34082 as well: http://www.textfiles.com/bitsavers/p...dbook_1991.pdf There's more reference material, but it tends to be fairly technical.

--- I do want to add something here: you claim you just want to see if 'Amiga fan boys' are exaggerating, but why didn't you just google these datasheets for yourself? You'd have known that the claims where true and not had have to SHOUT about Amiga History Guide just because you don't believe something. Last edited by roondar; 05 August 2018 at 23:55.

And I am surprised of it as true,because while on magazines I ever read about amiga in video studios I never read about 3d dedicated chips for amiga.. Howewer,you know something about the a2500 with the 3d chip?It is in a link I posted. Last edited by Amigo79; 06 August 2018 at 00:10. |

However, those arcade games used two of them and had an additional TMS34012 as a coprocessor to help with the heavy lifting. So, while it's probably possible to use an A2410 for 3D acceleration of flat shaded polygons, it won't be nearly as fast as either of these arcade examples. It should still be much faster than using just the CPU and/or Blitter though. Do note, I am personally unaware of any such use for the A2410. Last edited by roondar; 06 August 2018 at 10:21. |
