I need to texture a movie on a triangular layout.

Is it possible to do that with jit.gl.mesh or else ?

How to specify the dims of the triangle for such a geometry ?

Have you tried using the texture coordinate input (inlet 2) of jit.gl.mesh?

It seems to do it, but I'm asking how to specify that is called the 

"texcoord array" (nothing about in the help file)

Could you give a little example or any trick ?

Here's a crude example. The texture coordinates need to be specified for

each vertex that you're drawing. Texture coordinates x y are specified as "s

t" to avoid confusion with position x y. If I remember correctly they range

in the y direction from 0-1 and x direction 0-aspect ratio. (0,0) is the

I think in this example the texture is stretched since I didn't adjust the

values for the aspect ratio of the texture/screen. I leave that to you. Also

I'm sure you'll find a better way to fill your matrices ;-)

I'm going to study that.
Many, many thanks.
