Glass shader

[Temechon]

Hello all, 

 

I'm looking to create a glass shader that I can use in my Babylon projects, but I cannot achieve the effect I would like to have.  

 

Here is my code : https://dl.dropboxusercontent.com/u/17799537/08_GLASS.zip

 

And an example of what I have so far is attached to this post. I don't know how to have the transparency required on my sphere...

 

Thank you for your help !

Could you explain what you want your shader to do?

[Temechon]

Hi Delta, thank you for your answer.

 

I would like to create a glass sphere, like in this example : http://stemkoski.github.io/Three.js/Refraction.html

You should do the same as this demo:

the material I used for the water has a refraction part. This is exactly what you need here:)

I tried to used the water material on my sphere, here is what i have so far.

How can i set some transparency on my sphere ? I should be able to see through my sphere.

 

I tried to use "hasAlpha", but I certainly don't know what I'm doing...

 

Thank you for your help !

You have to define that your material need alpha blending:

WaterMaterial.prototype.needAlphaBlending = function () {
return true;
};

 

And in this case, you should specify the alpha value of every pixel produce by your material

[Temechon]

It works with the alpha blending. I had to update the shader but I have now some transparency.

I removed the bump texture and the reflection texture as I don't need it.

 

Next problem : I would like more refraction that I have right now. I tried to update the refraction level, and tweak some values in the shader, without any results...

 

The effect I would like to reproduce is the second image : I want to be as much realistic as possible.

Last picture looks neat =]

 

I wonder how to make it also...

[Temechon]

Made with 3DS, sadly... I want to do the same with babylon.

[GameMonetize]

You need a big specular effect, refraction like in the water material (but you need to take in account normals)

[Temechon]

Sadly, I was taking into account normal, maybe not in the good way...  I think I will put aside this experiment for the moment, I cannot find/create/reuse a correct refraction shader.

did you have a look to the refraction postprocess demo I used on babylon.js ?
