Does micropoly / tinypoly texture mapping have disadvantages?
I am thinking about making a series of mesh models that use one texture map, with a rainbow of colors. Then I would like to scale down the unwrapped polys into micro-poly's, so they mostly get a solid color.
I did a test with a cube, and it worked well. Before I start making a bunch of models, I'm curious if there are some disadvantages to this that I don't know about. Is there a performance penalty? Rendering artifacts? Colors bleeding from mips maps? Anything else?
Edit: Screen shots included of around 50 cubes rotating at different speeds and texture that shows an example of how I'm making the unwrapped mesh.
Just one man's opinion, it seems like an OK idea.
Of course, it depends how many triangles you are using, like anything. If you mean maybe a few thousand on a face it should be fine right?
it would be interesting to see how shallow angle (anisotropic) issues work out - but you've tested that. Why not include a screen shot of your tests?
BTW "polygons" haven't been used since like 1950 :) it is simply triangles
I was using polys as a generic term :) I updated with screen shots above. I'm not seeing any artifacts. I think I will create a more complex model and do rotations with it to identify potential artifacts. Not sure what the best test would be.
"I was using polys as a generic term" ok, it's not 1950 :)
its a good question could you add a screenshot showing the large cube with a shallow viewing angle, to see if you have any anisotropic-like problems
could you please add a shot showing the mesh (ie, in editor) so we can get a feeling of how many tris you are using
nice one
Took some screen shots but it won't let me upload any more. I placed a couple cubes near the the camera and made them have as close to a 1 pixel edge as possible, and I didn't notice any artifacts. Also deployed to an iPad and it worked the same.
