Wanted to help find any bugs and what not and try some 3d stuff. I feel like posting screens even if they aren't impressive or make much ( if any ) sense.

I think I'm going to make a 3d rpg battle system (for fun). Ala star ocean 2 on psx. Of course I'm only probably going to be able to take it so far before it turns into 3 million pounds of work.

I haven't had much time to play with programming stuff as I'm studying music composition (and not making too much progress to boot!). Oh well..


1. bouncing "hello world" text+3d sprite+random block mapping. Is there any kind of filtering that you can apply to poor blocky/muddy sprites like mine to make them look pixel perfect or remove the horrible blocky texture thing going on?

    Post the code !

      All 3d rendering is bilinear filtered.  So if you rotate/scale an image up, this will 'smudge' the pixel to smooth the result and vice versa with scaling down.  If you disable filtering, then you'll loose pixels.   It'll look the same (give or take) as an FX image.    You can test this yourself just changing the line    LOAD3DIMAGE "image2.png",1  to    LOADFXIMAGE "image2.png",1

Kevin's video feedback effect with pers. sprite, text.

Kevin, is there a way to change the filtering on the texture of a sprite to some other type of filtering? If not whats the command to remove bi-lin filtering on a sprite?

I think I'm going to try creating a single sprite matrix like you did in one of the demoes, despite I don't get the code.

Atm, there's no way to change disable filtering.

Hey, I must be forgetting something, but I'm trying to do a 1+16 inkmode, 0.1 alpha box, but it's sending the FPS to...well...rock bottom. What are the rules for having something done on hardware when you're doing such alpha stuff? I know it's insanely fast when you do it right.

  Most of the 2D functions don't have direct 3D acceleration.   More over,  In terms of the 3D device, it only works with the screen.

Ok, so obviously polygons are always 3d accelerated, got it. ...Another question: If I do a 3d terrain with a sprite, how could I implement culling to shave off a few frame per second of rending time?

No, only when rendering to the screen.

It already is.
