Hi All,
I seem to have a problem, and like most problems I am trying to figure out if its mine or somebody else's.
I have had a lot of fun with texture mapping various pictures onto various shaped surfaces. I find however that when I get start cutting up images into little triangles and start texturing in some non-linear way - pic a piece of the picture from here or there using the u,v parameters that sometimes I just can't seem to get the correct pieces of the images. I have quadruply checked all the math and I am fairly certain that I am , in principle, paremetrizing the thing right. But when I don't sweep nicely through the image with sequencial u s and v s, that, well, it goes to crap. And it goes to crap without a message. It just seems that the NORMALIZED mode is cutting out on me.

OK, now I admit that it could be me. So so so... I am asking the powers and the gurus and the ones in the know, if there is some kind of hidden requirement about vertex ordering in NORMALIZED texturing that I need to know.

If not, well, i suppose that the code needs to be checked again (after more sleep).

Thanks for anything you can think of. And thanks, as always, for Processing!

using the non-normalized mode just converts all the coordinates to the normalized version behind the scenes before it's drawn, so it's possible there might be an error in how you're setting it up..
