Texture Patch

Show a 3D triangulated mesh ( patch ) with a texture

Description

This function PATCHT, will show a triangulated mesh like Matlab function Patch but then with a texture.
 
  patcht(FF,VV,TF,VT,I,Options);
 
  inputs,
    FF : Face list 3 x N with vertex indices
    VV : Vertices 3 x M
    TF : Texture list 3 x N with texture vertex indices
    VT : Texture Coordinates s 2 x K, range must be [0..1] or real pixel postions
    I : The texture-image RGB [O x P x 3] or Grayscale [O x P]
    Options : Structure with options for the textured patch such as
            EdgeColor, EdgeAlpha see help "Surface Properties :: Functions"
 
    Options.PSize : Special option, defines the image texturesize for each
            individual polygon, a low number gives a more block
            like texture, defaults to 64;
 
  note:
    On a normal PC displaying 10,000 faces will take about 6 sec.
 
  Example,
 
   % Load Data;
    load testdata;
   % Show the textured patch
    figure, patcht(FF,VV,TF,VT,I);
   % Allow Camera Control (with left, right and center mouse button)

I'm using 2008b. The example did not texture map correctly. I did not get the image shown. Something is wrong.

*Peter-bone,
You can try to change the figure “Renderer” (painters, z-buffer or OpenGL), after you displayed your textured-object.
set(gcf,'Renderer','OpenGl');

But it can also be a problem with your video-card driver.

Perfect job! Thank you! You saved a lot of my time. Just one remark: in the comments/help you wrongly specified the size of the input matrices FF, VV, TF and VT. They should be transposed.

[Luca Baglivo]

It would be appreciated to change the help with the correct matrix sizes.
A strange thing I found is that it works correctly only if I flip the x and y image coordinate in the matrix, could you check?
Finally, with gray images it show color-mapped texture. The work-around I found is to use three equal layer of gray levels like a color image.

This is awesome, I have been looking for such a code for a such a long time. Congrats.
