Bubble Glass Bowl

[ZooHead]

I found this very heavy candy dish that belonged
to my parents and I had to make a model of it.

The base has an array of bubbles trapped inside.
Rendered with the Cheetah renderer.

Here's a render that shows the clear and smoked glass more clearly.
I used Falcon and changed the HDRI.

Quite surprising! I deduct from the #1 image that whoever recorded this image is invisible in convex reflections.
No wonder them folks are called Mainiacs...

 

[ZooHead]

Must be a vampire!

@ZooHead , is it possible to randomize the position of the bubbles in glass?
They appear to be on a grid. (or maybe they are in real life?)

They are in real life on a loose grid more like effervescent bubbles in soda.
I tried to keep it very close to real except for the number of bubbles, the real one has more.

From the look I wonder if you messed up with the normals somehow. The normals of the air-bubbles should point inside:

When the particle system is used the "Particle-tag" can randomize properties of elements used.

 

[ZooHead]

I already did that as you can see.

 

[frank beckmann]

Mmmh - I still wonder why we can´t see the bottom of the bowl?

 

[ZooHead]

I don't know, that is strange. I thought it was how a big glass blob would look but...
Refraction is set to 1.5.

Here's a side wire view.

 

[frank beckmann]

I thought you have that object in front of you. I will alter my attempt by adding the top part and see if this somehow will hide the inside. Maybe a part of texture treatment is causing this. Not sure - but I still expect seeing the bottom while looking at it. Is the top a different/separate object or is there a gradient used for the "smoke" effect?

 

[ZooHead]

It's just the angle of the camera.

I raised the camera and there it was.

And without the top...

Here's a photograph I took of the original.

Interesting piece of glass work.

Ok - main difference and impact is of course the used HDRI - yours seems a studio set up while mine is some industrial environmental; one piece of glass, dielectric shader with light greenish to dark gray tint gradient shading:

 

[Charless]

How its done?

You're spot on regarding the HDRI.

Don't forget the reflection of the piano keyboard in the original photo reference

 

[frank beckmann]

Are you saying I didn't have to push that piano, which weighs tons, out of the room? Damn.

Good eye, that's my Korg T3 synth in my photo.
