diamond object

I tried to only reuse some of the standard stuff without custom shader :-)

this is impressive. those sparkles are amazing @Sebavan

@NasimiAsl very nice. about real inner reflection and ray refraction, can we do that in live render but limiting the bouncing effect for 2 or 1 and see how it looks like? that will be the very close to reality. and we have to take in consideration the index of refraction of the diamond material, 2.417

The reason why I wanted that is that modifying the parameters of the diamond(depth, crown angle, pavilion angle), will impact the sparkle. But with fake approach, all the diamonds will look the same no matter if you stretch that diamond like a pencil or flatten like a pie. Not in reality. So that is the whole point if you can do that. But not sure how will be possible in live render...

thanks again @NasimiAsl

this is a big project for webgl  @Emil

InnerReflect = (inner face reflection ) most be calculate with  a face y face and it is like you make all diamond inner Face like mirror and you most be make texture of that  and mix all face textures in a cube map and replace that with that mask ( http://i.imgur.com/QxxS3VP.jpg)

it is not just shader stuff more physics stuff and we have restriction about reflection

read this : 

so maybe opengl can do that in this time
