texture video on a trapeze

    Dec 03 2010 | 4:27 pm
    Hi all,
    i want to texture a video on a trapezoid quad.
    I generate the quad with jit.gl.sketch.
    My problem is the way of texturing the video on the quad : 2 triangles !!!
    So when a distort the quad by changing the position of one point, only the concerned half part of video is distorted.
    I want my whole video distorted when i change one point of the quad...
    any idea?
    Thanks for helping

      I think you might have to specify texture coordinates per vertex, for example: gltexcoords 0 0,
      glvertex (vertexcoordinates),
      gltexcoords 0 1,
      glvertex (vertex coordinates)
      See the complete list of glcommands in the jit.gl.sketch help file.
      You should take into account the order of the vertices (I think it is usually counter-clockwise). Please post a patch so that we can have more information about what you want to do

      Thank you very much,
      actually, it works with jit.gl.mesh... much easier than jit.gk.sketch for this stuff...
