Hi Gilles,
Thanks for your comments.
Unfortunately I cannot give a full movie right now, I have to take certain
permissions.
However, I would certainly love to contribute back to POVRAY.
The features I have added so far are -
1) Hermite interpolation - its better because it gives smoother
interpolation and uses more information
2) Given a density mass, the user can specify a threshold and an epsilon, so
that all the values below
threshold-epsilon are clamped to zero and and those between threshold
to threshold-epsilon are
smoothly interpolated towards zero. This is basically to get different
shapes with the same density
volume without getting any artifiacts due to truncation by a threshold.
3) Use of temperature instead of density to specify the color of the media.
Adding perlin noise to the
color values to simulate the details.
I am new to the open source community and not quite sure of the procudures
involved in here. But
surely if these features are useful to others I will be glad to clean them
up first and share it with others.
Regards,
Maurya
