2D Warp texture mapping create curved diagonals...
Hi,
i'm trying to map a texture on 2D surface with jit.gl.mesh.
My problem is:
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...
Thanx for helping
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.
hello list,
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 ?
some special gl hint, or another object i should try.
i habe to finish my project on saturday ....
i have attached a smal dem, which shows the problem.
any help would be graet !
