texcoords on jit.gl.mesh
Can anyone tell my small brain what I should do to correct the texture coordinates in the patch below so that the texture fills the whole plane that is created?
(My end goal is to create a patch so I can move the corners of my texture to make irregular, rhomboid shapes so in order to correct for projection distortions. Like an irregular keystone kind of thing.)
im not sure but
texture coordinates cannot be less than 0
between 0.0 and 1.0
so make a separate matrix for the texcoords
on the gl.mesh, try:
tex_map 1
tex_plane_s 0.5 0. 0. 0.5
tex_plane_s 0. 0.5 0. 0.5
attach this to your gl.mesh to adjust further (courtesy of wes smith)
brilliant! just the info I needed.
I just added a pictslider in a subpatcher that lets me move the corner of the plane around so I can cornerpin it to a projection surface.
thank you both. you rule!
