Hello,
I am working on a snow/icicle macro currently, and due to certain issues
that I have faced, my code has forked....which is not at all what I desire.
I have three problems. Two have been solved individually by the fork, but
must be integrated to be truly considered "resolved". The third, I haven't
any clue how to approach. I shall elucidate:
1) Icicles not "blobbing" together (solved in SnowTest_2)
The solution to this problem required that I estimate the size of the
bounding box resulting from the application of snow to an object X...but
resulted in initial blob placement insufficiencies.
2) Initial blob placement errors (solved in SnowTest_3)
The solution to this issue required the actual min/max extents of first
the initial object, and secondly of the union of the snowed on object and
the snow. This resulted in the inability to blob the icicles together as
found in nature.
3) Blobbing of the snow *and* the icicles. This is unresolved.
What I am left with, are essentially two issues:
A) How to integrate SnowTest_2 and SnowTest_3 so that the icicles both blob
together AND are positioned accurately, to be used in the solution to (B)
B) How to blob (A) with the initial snow.
As is, the parse time for my snow macro *with* icicles is 1 second in one
method, and slightly longer in the second.
I know that I am so close to the solution that it hurts, but I've been
looking at it so long I can't see the forest for the trees.
I will post the source files required to evaluate this issue in p.b.s-f
(same thread name), and successful contributors to the unified resolution of
these issues shall be credited in the final release....I'm almost there! :-D
To those who wish to assist, please comment any references to SnowTex0 and
Ice2 and uncomment the vector pigments within the snowTest and icicleTest
macros, to avoid long renders. I have included the snow texture include
file, just for S's and G's.
many thanks,
ian
