Hi all,

Trying to do scene in which I apply a texture to individual letters in a
word (as opposed to applying the texture to the whole word). However this
involves looping through the code for each letter - this then makes
positioning the text a problem - each letter in the word is spaced equally -
like when using a fixed width font.
I have tried using the new megapov features min_extent and max_extent to
work out the position for a letter based on the size/position of the last
letter, but cannot get it working.
Has anyone got any code that does this?

Thanks

Reuben

Well, that sounds like the right procedure, so it must be some little
coding error.  Can you post your code?

You might want to look at the CircleText() macros by Ron Parker...they 
include a macro to determine the width of a character, and "manually" 
position each character of a string to form a circular text object. It 
shouldn't be hard to modify these macros to do what you want. These 
macros were posted in povray.text.scene-files:
