Hi!
This is my first post here in pbi and I hope that the motif is suitable
enough... ;-)
It was my first real attempt at making an image with heavy usage of
radiosity.
The "floor" is not an isosurface but a mesh created with cloth 0.4.1.
Hope you like it.
bye
Mischa

I can't get over how many variations there are on this simple theme. Nice work!
Can you point me to "cloth 0.4.1"? I think I could use it in my current project.
Thank you

I like it. Is that a quilted normal on the floor? There appear to be
small bumps (particularly in the lower left). Nice effect anyway.

Sure I like it! And welcome to the group. :-)
I must say, this image is good enough already and easily qualifies as a
first post. But to give a few suggestions, since I'm writing anyway: I think
the image would benefit from stronger colours (mainly on the balls) and
reflections with better proportion between specular highlight and indirect
light. To achieve this, you could raise the ambience of the neon-light
cylinders (there is no need to mess with the level of reflection on the
ball - material), assuming the entire room isn't lit by radiosity... If the
entire room is lit by radiosity, you should lower the radiosity-brightness
value, in addition to raising the ambience of the light-cylinders...
Good luck,
Regards,
Hugo

Well, I tried several options with the colours and the ambient value.
Unfortunately I was not able to achieve the right effect without a
light_source so I added one additionally to the ambient cylinder.
Do you like it better like this?

Yes, I definitely think this is an enhancement! Perhaps the cloth could use
a tad of specularity as well; I mean a broad, dim highlight. This can
probably be achieved with the specular & roughness keywords only ... true
reflections (and in addition: blurry reflections) would slow down the
rendering by too much, considering what you get in return.

I'm not surprised. This is hard to do with radiosity alone, because the
direct-light is being emitted from a very small area. So it's a good idea to
use traditional light_sources as well. Even the professionals do this, all
the time. :-)

Hugo

Btw, I suggest adding fade_power 2 to light source, it always make scene
much more photorealistic

Wow! I love it. I have to try cloth 0.4.1 myself
sometime. I have the link now. Thanks!
