i'm trying to map a texture on 2D surface with jit.gl.mesh.

when i warp the surface, diagonals are curved.

Is it possible to have a mapping way wich preserve straight diagonals?

(without changing Z position of course...)

i think it's possible if the rectangles in the surface are not equispaced...

they are curved because you are sending the 2x2 geometry matrix to a 10x10 matrix with interp on.

just get rid of the 10x10 matrix.

i have a similar problem with the deformation of a texture
on a mesh.
i want to deform a movie with a triangle by adjusting its
cornerpoints.

if i use a jit.gl.mesh the outlines of my triangle gets
curved. i wont to keep it straight.

i have tryed different dimensions of the controlmatrix
without success :-(

i also tryed the jit.gl.nurbs. the result is also a
curved distortion of my texture.

with a textured quad drawn with jit.gl.sketch i had the problem,
that my texture got a kink.

does anybody has a tip for me ?

any help would be graet !
