Hi

I've convert some 3DS-Files to POV-Ray. Now the object looks like

#declare MyObj=union {
  union {  /* subobject 1 */
    triangle { <......
    triangle { <......
    triangle { <......
    triangle { <......
  }
  union {  /* subobject 2 */
    triangle { <......
    triangle { <......
    triangle { <......
    triangle { <......
  }
  .....
  texture { .... }
}

If I render the scene in POV-Ray, it Povray render as much as longer.
Example:
an empty room (4 Walls , one light source, 800 x 600) needs 2 minutes
with this 3DS-Object, which you is only 50 x 50 pixel large Povray needs 6
minutes, because povray need more time to render the wall, where you can't
see the objects. I hope you understood me.

Is there the posiblity to speed it up. I've tried bounded_by, but not with
better results. Could you give me an example or a tip?

thank you
  frank

Use 'mesh' in place of 'union' for each 'triangle' section, but you still
need to 'union' them together as a whole.
