First try: Real 3D texture with triangles, Pros: 1 single texture, Cons: low framerate trianglec2.bas (25.54 KB) Second try: 3D Texture Quad, Pros: 1Only Texture, Cons: Framerate and Warp! cubes3D4.bas (15.72 KB) Third Try: _maptriangle 3D, Pros: High Framerate, Cons: Texture update every frame trianglecMaptriangle.bas (29.31 KB) (Line 117): Why one 3D _maptriangle over another 3D _maptriangle Doesn't Work!! |

ubi44 I am guessing you know allot more about _GL... stuff than I. Did you learn just by playing around and checking Wiki allot or some other way?

I'm just learning by playing with the instructions, but I didn't understand the wiki with the addition of sub _GL! I have to understand because we can make shadows etc... But for an animated texture my work with _maptriangle and without sub _GL is good 4800fps on core i9 10900k!

my work doesn't use sub GL and I find that maptriangle is sufficient even if I have to redraw the texture every frame.
My question is whether multiple 3d _maptriangle can overlap.. in my example with -maptriangle the 2D overlaps with the 3D but not the 3D on 3D...
Otherwise with certainty, I can't compete with Galleon

I don't think _MapTriangle 3D can overlap, because we have to place them 0.1 units away, which can just be viewed from the side though. So it won't be a good idea. The other thing you can do is overlap the textures first, and then use _MapTriangle 3D, this way it will draw only one overlapped triangle. There are no other ways I can think of overlapping. If you wanna see how I used _MapTriangle, maybe you could get what you need, just head on to the drawcube sub: 230726.zip (5.67 KB) I made this as a minecraft clone a while ago when I used _MapTriangle 3D, but it just drops framerate. |
