Hi all
here it is a new version of the black hole in my scene … it is more or less a variation of the techniques used in the previous rendering, but with some new things … mainly I’m using now a plane (this means that the donut shape is only half … but since the image is static there is no problem, you cannot see the other side of the black hole … cg is not the art of reproducing reality, but of faking it :)) …
I’m using some texture maps to do displacement of the plane (true displacement, not a bumpmap), both for the donut shape and for the spiral shape … I added perlin noise displacement on the donut shape to simulate clouds … than, the last step, I painted in GIMP an alpha map that is a circle with a fuzzy border … here it is the result … the jet is a fake one (an emittive cylinder), need to work on a better jet for sure … I am also not happy of colours and lighting, but this will come later …
I want to paint a better starfield (the one used here is just a 5 minute try with GIMP) and use the same techniques of the black hole to provide some interesting nebulas for background … also this will probably come later, because I now want to start to model some ship …
Any comments will be really helpful.
Bye, Riccardo
