water in the cup... ?

hi all... Ok, we played around with glass, finding out that the refraction for glass was somewhere around 1.517....

now, how about adding some water to those cups... just what is the refraction levels, as well as any other setting involved within CE or C4D, in order to make nice water... and if we took this one step further, and created a whole bunch of tiny spheres around the edges of the water line etc, then would these be the same values?

Water settings = ?
bubble settings = ?


I hope that we can find these answers out http://www.talkgraphics.com/images/smilies/smile.gif

ok, Just recieved info that water refraction is 1.33...

anybody have any thoughts on this?

anybody care to test this setting out by placing an object within a glass mug/cup and doing some renders ?

Hi Gidget,

I'm not really happy with the lighting in this, but I've spent hours trying to get it better. One cup without water and one with.

Yeah Soquili, know what you mean. I've been playing with this for hour too and just can't seem to get it right. Refraction index is set at 1.33.

Here is my attempt. Used the glass material, from earlier post. Used 1.33 for Refraction on water. No bubbles yet.

I'm a stubborn old f**t. Played around for a couple more hours. Added an array of lights and put the whole thing inside a huge reflective sphere. Still didn't get anything close to what I had envisioned. Finally enable the phong tag on the glass and water and limited the angle to 80 degrees. Also offset the checkerboard material on the floor slightly in the +X direction. Glass is refractive index of 1.517 and water at 1.33.

Very nice work Fossman and Randy. Guess we have to have a go at bubbles now http://www.talkgraphics.com/images/smilies/wink.gif

Here's mine, I Rendered in Bryce. The Bryce materials editor uses a slightly different set of numeric values, but I believe its about the same end result, Eg. refraction value is 133 instead of 1.33, bumpy colored glass mat. refraction = 152.

Fun http://www.talkgraphics.com/images/smilies/biggrin.gif

And here´s mine: Modelled in Wings 3D and rendered in Vue d'Esprit Pro.

Looking good everyone, Bill 2nd attempt much better.

Now how about some bubbles?

Nice work here you guys. I took another kick at it with caustics.

Arnold

Nice work Mike and Paul!!

Arnold, looks good. Is it a trick of the lighting or do you have an ice cube in the glass?

Holy cow you guys... you are all really rock'n with this...

I mean wow... I just can't get over how great these entries here really are..

here's one from me... though no where near as nice as most of these super try's by you guys.... I want your secrets durn it

Soquili, yeah there is an ice cube in the glass, but the coloring is not coming out the way it should. Thanks

Arnold

my try http://www.talkgraphics.com/images/smilies/smile.gif

Good work Gidget and Miress!!

Here's a try with some bubbles.

Right on Miress... good looking glass of water, and nice to have you join in http://www.talkgraphics.com/images/smilies/smile.gif

hey, those bubbles look really good Bill http://www.talkgraphics.com/images/smilies/smile.gif Way to go... cool http://www.talkgraphics.com/images/smilies/biggrin.gif

You are all really doing super with this... http://www.talkgraphics.com/images/smilies/smile.gif

My favorite bubbles. http://www.talkgraphics.com/images/smilies/cool.gif

roflmao... that's priceless Mike http://www.talkgraphics.com/images/smilies/biggrin.gif

Thank you Gidgit http://www.talkgraphics.com/images/smilies/smile.gif...hhmmmm, let´s make some ice to cup...hm??? http://www.talkgraphics.com/images/smilies/smile.gif

OK. http://www.talkgraphics.com/images/smilies/biggrin.gif

http://www.talkgraphics.com/images/smilies/biggrin.gifooouuuh, good good....nice ice http://www.talkgraphics.com/images/smilies/smile.gif

Looking good you all. Here's my last try at this. Cubes and bubbles. Mike, I expected something else when I read "my favorite bubbles"? http://www.talkgraphics.com/images/smilies/wink.gif

Arnold

holy cow Mike, that looks really good... http://www.talkgraphics.com/images/smilies/smile.gif

holy cow again, wow Arnold, that looks really good as well... http://www.talkgraphics.com/images/smilies/smile.gif

geez you guys are good at this http://www.talkgraphics.com/images/smilies/biggrin.gif

Not as good as what you people came up with, but this is as far as I can push it with Blender. Learned a lot from this thread.

that looks really good Grafixman http://www.talkgraphics.com/images/smilies/smile.gif

I love the melting effect you did... http://www.talkgraphics.com/images/smilies/smile.gif

"Learned a lot from this thread"

Me too http://www.talkgraphics.com/images/smilies/biggrin.gif

and that's part of what further exploring and participating is all about eh http://www.talkgraphics.com/images/smilies/smile.gif it's so cool

hi people...your pic are very very good, better than my...hold on http://www.talkgraphics.com/images/smilies/wink.gif

my second and last try http://www.talkgraphics.com/images/smilies/wink.gif http://www.talkgraphics.com/images/smilies/smile.gif

Arnold, I haven't got a clue what your talking about. http://www.talkgraphics.com/images/smilies/wink.gif

Everyone did good on this subject. http://www.talkgraphics.com/images/smilies/biggrin.gif

nice one miress... http://www.talkgraphics.com/images/smilies/smile.gif

rofl... Mike, haha, too funny http://www.talkgraphics.com/images/smilies/biggrin.gif and a very good pose at that http://www.talkgraphics.com/images/smilies/smile.gif

Great stuff Mike, Miress and Arnold!!!

Mike, is that a 'Ginny' Fizz? http://www.talkgraphics.com/images/smilies/wink.gif

Mike it is best of the best http://www.talkgraphics.com/images/smilies/smile.gif very nice

Here's mine! http://www.talkgraphics.com/images/smilies/smile.gif I know it's a bit late but when I read this last night I couldn't resist. While playing around with it I also noticed a difference in the refracted image. I don't think the rays need to be so high but I wanted to get the full effect without having to test it by incrementing one ray at a time.

Does anyone know why those fuzzy grey areas appear (they are within the "water" and I'm pretty sure that they are the white squares)? I can't figure it out.

Also, I notice that there is a fine grey line between my water and cup. I took a copy of my cup and removed the outer portion of the spline so the inner portion was exactly the same as the cup (inside a lathe nurb). Is there a tutorial for making liquids in a cup somewhere?

Thanks,
-Tek

Hi Teknal,

Great looking glass and water. Those gray areas are probably shadows on your water object. Add a compositing tag to your water object and uncheck the Receive Shadows.

Hi Teknal, yes indeed,nice looking glass and water...

ya know what? You bring up some very interesting questions, to which personaly I have not the answers, but I would surely love to gain such... http://www.talkgraphics.com/images/smilies/smile.gif So yes indeed, di everyone make the "water" the inside dimensions of the cup, or halfway through, or all the way through etc? as well, I would really like to know how some managed to make the condensation look on thier entry's here...

good stuff Bill http://www.talkgraphics.com/images/smilies/smile.gif

Gidget, the images from me had the 'water' slightly smaller than the inside of the glass. If it touches or intersects the glass you can get some unexpected results. Jens told me this last year when I first started using Truespace.

Sometimes the results can be nice though.

You want your water to be ever so slightly smaller than your glass. Interseting gemotery makes for some strange artifacts when rendering.

Try upping the size of the shadow map. This can be found in the light settings.

Also You can try using a boolean operation.

Gidgit, I think it was the ice http://www.talkgraphics.com/images/smilies/biggrin.gif, but here's a photoshop postwork effect achieved by layering a duplicate image on top of the original, applying a gaussian blur and layer mask.

Wow, this is some very good information guys... thank you Bill, Randy, Mike... and Jens http://www.talkgraphics.com/images/smilies/wink.gif http://www.talkgraphics.com/images/smilies/smile.gif

Bill, great Illustration of the differences, thank you http://www.talkgraphics.com/images/smilies/smile.gif

Mike, thanks for that post op example, really cleared some things up for me http://www.talkgraphics.com/images/smilies/smile.gif
