dear mark, oh yes, wonderful, I am curious how to build new vsl shader, cause of the learning curve myself! ;-) thanks for the tipps and your critics...
you said "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"... o.k.:-))) how to you build this one? If you have an exercise, please upload it here! - My glass/Ice shaders are not perfect, it's a time spending work, but the various ways (often complex and not so easy to handle) to the right shaders are be worth it! I am looking for the right look for my ice cube or soft ice pot! best regards, have a nice day, see you, Frank Brübach -----Ursprüngliche Nachricht----- Von: "Mark Heuymans" <[EMAIL PROTECTED]> Gesendet: 04.06.08 00:21:59 An: <[email protected]> Betreff: Re: last little scene with glas/ice texture :-) 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 _______________________________________________________________________ Jetzt neu!
