mantra scripting

[Jason]

Did you know that you can script mantra?

Did you know that its a command structure thats a subset of hscript?

You can make for/next loops and define strange and interesting things inside of the ifd and mantra will render them.

# Define some geometry named "geo".  It is smooth shaded.
    ray_detail -s geo $HH/geo/defcam.bgeo

    # Define the camera and output image
    ray_picture ip# Set the output image name
    ray_resolution 256 256# Set the output resolution
    ray_zoom 1# Set the field of view
    ray_clip .01 100# Set near/far clipping planes

    # Now, instance the geometry 5 times.  We can use the standard
    # hscript expression evaluation and variable expansion to position
    # the objects.
    for i = 0 to 4
      ray_object object$i geo# Define an instance

      # Transform the instance
      set x = `.2 * ($i - 2)`
      ray_transform 1 0 0 0  0 1 0 0  0 0 1 0  $x $x 2.5 1

      # Apply a surface shader to the instance
      ray_shader constant clr `rand($i)` `rand($i+.1)` `rand($i+.2)`
    end

    # Tell mantra to render the scene
ray_raytrace
ray_quit

Do you want to know more??

Thanks Jason. Do post more. Curious, are there any updated docs for this? The version I have is dated back to v4. Not sure if there's any changes to the structure.

LOL!

Nice one Jason!! wooohooo!!

Should I even ask where you got that from? --- doesn't matter, it has now been Wikified, Baby!

If it weren't for the fact that i'm in a mad push to finish a job, I'd give it a whirl right now!

Thanks!
