Change :

you can add something like an attenuation coefficient to "walls"
print the number of rebound or a calculated value
colorize follow one of thoses values

nb : calculated values are not real physical values but a way to know what kind of attenuation a ray would have

nb : skip 1.2 version because it's a great improve (odd numbers are minor revisions)

nb : next version would be more optic oriented

Comment by greg bethel on March 9, 2012 at 11:03am: Hi Guillaume. Here is an example of trimmed surfaces not working. Set the brep in 'Geo 1 ceiling' sublayer to replace the untrimmed flat surface ceiling in the definition: acoustic_shootV1.4_simple_test.zip

The error in the script is "Type conversion failed from Brep to OnSurface".
