Texture Patch


Dirk-Jan Kroon (view profile)


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

| Watch this File

File Information

This function PATCHT, will show a triangulated mesh like Matlab function Patch but then with a texture.
    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;
    On a normal PC displaying 10,000 faces will take about 6 sec.
   % 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)

how to get these parameters TF and VT

how can we use this function to map texture on a 3D model from a 2D face image.(Point to Point texture map. Only face texture and leave everything else in the 2D image.) .... ?

@tn_with_8fusa: Thank you very much! To enable the code on "any" Matlab Version, I made the following adaptation:

x1=sizep; y1=sizep; x2=sizep; y2=0; x3=0 ;y3=0; % original
version_str = version;
index_year = regexp(version_str,'(R');
if str2double(version_str(index_year+2:end-2))>2013
y3=sizep; %new

very good work! Thank you!

In 2014b, there is a problem showing texture.

When 127 line of patcht.m is corrected as follows, this problem is settled.

x1=sizep; y1=sizep; x2=sizep; y2=0; x3=0 ;y3=sizep;

I would like to know how you calculated VT and why the number of VT is different from VV.

I did not understand something else in your example is VT why the number of vertices is larger than vv.

is that this function is limited by a number faces or not

Hi, I cannot understand the following:

1) What is the "TF" variable and how do I create it if I have vertices (VV), trinagles (FF) and texture coordinates (VT)?

2) In your "testdata", I see that the number of texture coordinates in VT are not saem is the number of vertices. However, should that not be the same or am I missing something here?

Your guidance is highly appreciated.

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

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.

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.

You can try to change the figure “Renderer” (painters, z-buffer or OpenGL), after you displayed your textured-object.

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

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