Deadend85 Posted December 8, 2023 Share Posted December 8, 2023 I am new to coding for consoles and new to using this api, i have a question. How can i make 3D shapes, i have a formula already for drawing lines, i just dont know how to send it to the gpu or display it Link to comment Share on other sites More sharing options...

Well I have and im using C where the documentation "Jaguar Technical Reference Manual Tom & Jerry" it specifically says thats its designed for Assembly, I have looked at at the reference projects and i do not understand the functions used so i try to look through the reference manual for Jagstudio and Raptor API and they dont have documentation for the functions or the documentation doesnt really say how its said.

Zerosquare Posted December 11, 2023 Share Posted December 11, 2023 The GPU doesn't do 3D. It has a few features that can help with rasterizing, but it can't even draw a simple flat-color triangle by itself. You need a complete 3D engine, which JagStudio doesn't provide. If you want to get started with JagStudio and Jaguar coding in general, 3D is definitely not what you should start with. 2 Link to comment Share on other sites More sharing options...

To be more a "Korinthenkacker": The Blitter draws the lines which form the triangle. Or any other polygon (At least with all my experimenting, I did not find a way to make the Blitter draw a triangle.) The Lynx' Suzy can really "draw" triangles. 1 Link to comment Share on other sites More sharing options...

Actually Leonardo did not paint the Mona Lisa. What, why? He painted colors and shapes that look like the Mona Lisa. Ok pal... Your Statement does not contradict mine.

Ericde45 Posted December 11, 2023 Share Posted December 11, 2023 the Jaguar was not created to handle 3D if you want to do 3D, you must do it like an atari STE would do the blitter does not even have the fill function of the Amiga so no, the blitter is only able to draw lines, either in all angles, or horizontal lines to fill some 3D planes, under the control of the GPU 1 Link to comment Share on other sites More sharing options...

When I saw "Leonardo" I actually read "Leonard", and thought, yes right Leonard did not draw 3D, only plain polys 🙂 (STNICCC2000) 2 Link to comment Share on other sites More sharing options...

Ericde45 Posted December 11, 2023 Share Posted December 11, 2023 a lot faster, amiga = 1985, jaguar = 1993 just the ram speed improvement is enough to justify that it is faster but not by conception. Link to comment Share on other sites More sharing options...

Cyprian Posted December 11, 2023 Share Posted December 11, 2023 anyway, GPU can handle 3D - e.g. Doom, Cybermorph or Iron Soldier 1 Link to comment Share on other sites More sharing options...

Ericde45 Posted December 11, 2023 Share Posted December 11, 2023 no, that explains why jagstudio has no 3D engine, because the Jaguar iself has no 3D engine in its hardware Link to comment Share on other sites More sharing options...

The reason is simple, it does not feature an 3D library, CJ did not write one, hence nothing to do with the Jaguar itself. 1 Link to comment Share on other sites More sharing options...
Ericde45 Posted December 11, 2023 Share Posted December 11, 2023 lol if the jaguar was really a 3D console, there would be a 3D gpu in it, and a 3D engine would be easy to code. 2 Link to comment Share on other sites More sharing options...

Ericde45 Posted December 11, 2023 Share Posted December 11, 2023 did you ever code anything on Jaguar ? if not, stop saying that nonsence about 3D and Jaguar you can do 3D on a ZX81 but this is not by design. Link to comment Share on other sites More sharing options...

And Jalaga is not exactly 3D. Does it use the built in 2D engine? Must be easy then lol. Link to comment Share on other sites More sharing options...
Ericde45 Posted December 11, 2023 Share Posted December 11, 2023 yes, it uses the object processor, clearly designed to make fast 2D objects it runs at high priority to ensure that. Link to comment Share on other sites More sharing options...
