Snow Shader for iphone

Graphics Shaders & Materials
1

just to get a quick response from more experienced people:

would it be possible to generate a snowsurfaceshader for IPhone, which does the following:

  • random camera dependant specular glittering (noisy spec map maybe ? )

  • have some of this typical bluey rimlighting kind of effect ( this should be something that is “surface normal to camera angle” dependent me guesses )

  • there is no need for slopeblending or similar, just a shader to produce a nice outside area/geometry completly covered with snow…

any realistic chance for something like this on iphone ?

thx :wink:

You don’t have any programable pipeline at hand, as such you are restricted to sphere maps and texture combiners, no dynamical noise maps or real spec maps at all.
