Hi,
I am interested in mapping 6 different images on the faces of a cube. I found
the full code for doing this here :
http://rwiki.sciviews.org/doku.php?id=graph_gallery:cube
But I am unable to adapt the code for my purpose. I would appreciate it if I
could get some help on the following points :
1. My images are jpeg images with dimensions of 1936*2584*3. Must I seperately
process the grey and rgb attributes as in the code in the above page. Would
appreciate it if I could get some explicit help on processing the image matrix.
I don't follow in detail how a square portion of the graphic is extracted
also.
2. Instead of a cube, I am interested in mapping images on a cuboid (l!=b!=h).
Could I get tips on how this can be done. How should the dimensions of the image
matrix be tailored then?
3. The following line in the code appears to identify and fix the corner points
:
coords <- rbind( c(0 , 2, 3), c(1 , 3, 2), c(3, 0 , 2), c(2, 1 , 3),
c(2, 3, 0 ), c(3, 2, 1 ) )
How should I read and understand the orientation of the cube corners from this?
A simple tip can get me started.
I would like to add some example code (to complement Romain Francois' code
on the rwiki page referred to above). But, as can be seen from my questions, I
don't understand this sufficiently to do this. But I hope that I have given
sufficient information to explain my problem.
Thanks,
Ravi
