vt should accept 3-component #14

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Right now, vt only works if there are 2 floats, and doesn't support the 3-float 
version, even if the third component is always 0.0

r16 partially addresses this problem.

r21 has a followup that completes the workaround; r16 only managed to parse 
permissively, but would stick the zeros in the texcoord stream instead of 
ignoring them.

With revision 21 we have this :

Textures working incorrect :(

What this can be?

Ok, thanks anyway.
I reported new bug. Textures incorrectly displays. See in issue 14

I think it means that exporter can't export UVW from obj to utf8.
That's bad, really.

I believe this might be a bug in the viewer. It is hard to tell because I don't 
have the time right now to debug THREE.js (I'm not super familiar with it). My 
own tests work.

oh! that's nice!
can you give me a code on which you tested?

I bet three.js (or something) is vertically flipping either your image or the 
texcoords. Try that first.

Try what? Sorry, i don't completely understand you.

Try flipping the texture image upside-down, either in an image editor or using 
UNPACK_FLIP_Y_WEBGL.

Equivalently, you can invert the y-texcoord, either when you load the model, or 
in the vertex shader.
