hello again, dear realsoft friends: a little new picture with ice/glass textures... I will build now a bigger scene with various vsl shaders and nurbs objects, perhaps I can create an "icecream pot" :-)
added picture: ... rendering times: 3:56, image size 640x480, recursion depth 4, two different ice shader, glass-textures, mirror texture, having built this scene with only one ligth source! ;-) and some nurbs objects. So long, have a nice time here, good realsoft renderings, see you, frankolino and I will make a time limited break ps: what about this forum? Why it's so calm here???? -------------------------------------------------------------------------------------------- Hi Frank, The ice is getting better and better! I finally have some time again to pick up fun 3d stuff like this, just finished a few hectic weeks of commercial architectural projects... I remember some talk about Fresnel-shaders... maybe here's an alternative. A bit of VSL: I usually map channel ray*normal to Reflection directly with a Curve object, with horizontal range (ray*normal: the angle between camera and surface) from -1 to 1. This way, you don't need the Abs Value and other calculations. I even found a table with real angle/reflection values for water in an old book (Minnaert, "De Natuurkunde van 't vrije veld). More to follow, I'll upload some shaders if you want. Cheers, -Mark H
