tcolor (a fast pcolor that likes RGB images)

Draws an image as a texture to a plane.

Description

For use like pcolor but with c as a true color matrix (uses texturemap for speed)...
 
  H=tcolor(x,y,c[,method])
 
  valid methods are: 'corners','normal','triangles'
 
  The normal method is texture mapping unto the plane given by x and y (which may be distorted arbitrarily)
 
  The 'corners' method is the fastest way to draw. However it requires that the area is non-distorted... E.g. that the box defined by the corners defines the area.
 
  The slowest method is 'triangles'... (sort of like pcolor). But shading interp works with it.
 
  c=imread('C:\Projects\My Pictures\peppermint_girl.jpg');
  [x,y] = meshgrid(1:size(im,2),1:size(im,1));
  x=x+y/10; %skew the image
  H=tcolor(x,y,c,'corners')

Please leave a comment when you give such a low rating. If you report a specific problem then i'm sure i could fix it.

Works. Usefull function that fills a gap in matlabs plot functions.

Great! It is indeed fast and most important of all it can be used for rgb color image, good job!
