i'm trying to make an UI for a simple video player.

i need relative coordinates for each of the 4 points (corners).

to be clearer : my display is a rectangle ABCD.

x and y equal to 0 when it's the normal size.

i would like : xy for A, xy for B, etc.

1- why does the movie play with plane and not with quad ?

2- what are points 1 2 3 4 for the quad ? 1 = left bottom ?

how to use it ? what are the others (quad_strip, etc) ?

so i tried with jit.gl.sketch.
i could get what i want with quad.

3- what is "shapeprim tri_strip" ?
how to use it ? what are the others (quad_strip, etc) ?

how to play a movie as texture on "quad" using jit.gl.sketch ?

how to play a movie as texture on "quad" using jit.gl.sketch ?
pleaaaaaase.

you can use jit.gl.mesh with a 4x4 control matrix for verts and texcoords.

initially i wouldn't like to crop only but it's ok like that.

if somebody knows how to deform the picture with this 4 points, it's

welcomed too.

It seems difficult to manipulate texcoord matrix with screentoworld message to [jit.gl.render].

Coords are reversed and dont't follow the mouse (values given by the mouse aren't linked/mapped to texcoord.)

"Screentoworld" works fine with vertex array, look at the patch.

> texcoords are s/t vals not x/y vals
Sorry, could you be more explicit. 
What do you means by s/t vals?

go to the section called "Assigning Texture Coordinates"

thx for your help. :-)
