[Radiance-general] OBJ2MESH - UV Scale and Shift

[Giulio Antonutto]

hope this helps:

es.

shift by 50% and tile 10 times:


(X(Lu+0.5)/(1/10))-floor(X(Lu+0.5)/(1/10))

or
X(Lu+0.5)/.1-floor(X(Lu+0.5)/.1)

where X is the ratio X/Y of the image to map.

you may use directly these expression in colormap:

void colormap test
7 red green blue picture.pic 
. 
(X(Lu+0.5)/.1-floor(X(Lu+0.5)/.1))  
((Lv+0.5)/.1-floor((Lv+0.5)/.1))
0
0


the "." means no cal file

ciao

giulio


PS remember that you need to recreate the mesh for this to take
effect...

Subject: [Radiance-general] OBJ2MESH - UV Scale and Shift

Dear Group,

I have been recently using OBJ2MESH as part of my workflow. I am finding
it 
very useful. What I would like to know is if it is possible to adjust
the UV 
shift and scale of a pattern associated with a mesh? Say if a pattern
tiles 
4 times in the U and V, if I want for it to tile 1,2,3,6,8,etc. times
and I 
wish to shift the patern by 1/2, is there a method for doing this?


Regards,

Marcus
