Hi,
Particles again :)
I use a external particle system Part3d
(http://mark.technolope.org/part3d/) to generate data files of 2
masses of particles colliding. I have modified this program in order
to handle multiple colors, so I can separate out the various bodies.
Enclosed is the raw data: particle spheres colliding with each other,
acting on speed, energy & self gravitation.
Question:
In the end I want to make a animation of two planets colliding,
so I converted the particles to blobs. That went ok. Then I put a
image map of the earth on the blob.....what a mess....distortion all
over. No matter how much I translate and scale, i cannot get a proper
planet.
Has anyone done such a thing ?
Willem

Hello again. Can't say that I have, that I ever remember.
If you're using map_type 1 and applying the pigment to the entire blob (not
individual components) I don't see any reason for it not to work right. At
least until it begins to change away from a spherical shape. Once it begins
to distort away from a sphere the image can't map to individual parts
properly when using an ordinary image_map without uv mapping. I have no idea
if blob can ever be uv mapped. In any case, translate and scale shouldn't
matter for map_type 1.

He !, I am already crossing the boundaries here....

By the way, thanks for your particle stuff, I am still working on it...

It should be more or less ok if you add the texture for every component, before
you translate the component away from it's initial position. Hope this makes
sense :)
