Glass bottles - C4D lathe nurbs

Playing around with the lathe nurbs and some glass textures. The 'clear' bottle has a BhodiNUT shader. The 'green' and 'rose' tinted bottles use materials created with the material manager. B-Splines were used to make the shape of the bottles.

Bill, when I saw your bottle I got inspired. http://www.talkgraphics.com/images/smilies/biggrin.gif
I modeled with C4D. I haven't used my new version of Bryce very much, so I exported and used Bryce glass mat. -n- rendered. Bryce5 renders real nice, its capable of fine art but its so very slow. This is approximately a 30min render at the resolution attached, IMHO Its worth the wait.

Hi Mike,

Bryce does a very good job with that glass mat. Great model too. Thanks for the info. I'll look into Bryce.

Bill - Good job. You might want to use Fresnel and turn up your specular to 150, and make it narrow. Some reflection also would help.

Mike - Byrce has some great glass mats. Nice Render.


Here is a glass vase, rendered in C4D CE. Which I think is not bad for CE.

Hi Randy,

Not bad for C4D of any version. Thanks for the tips for settings. I had fresnel up fairly high, but didn't adjust the specular or reflection. I'll keep that in mind for future use.

Wow, these all are very nice indeed... I am inspird by all of your activity here to say the least... and will now go and drag out a few apps and do some glass just to see what we can come up with... awesome stuff gang. http://www.talkgraphics.com/images/smilies/smile.gif

Another try at doing a material for glass in C4D. Took Randy's advice and adjusted the specular and reflection. I used Xara to create the spline for the lathe nurbs.

All these lathed glass items are very nice! Soquili, you mentioned you used Xara for making the spline, how did you get it from Xara to C4D? I was trying to do that very thing earlier but could not figure out how to do it. How do you export the spline?

Thanks,
-T

Nice reflection map Bill, is it a palm tree? http://www.talkgraphics.com/images/smilies/biggrin.gif
<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR> How do you export the spline? <HR></BLOCKQUOTE>

Export the Xara line as an Adobe Illustrator (ai,eps) file.
Using the C4D objects manager, File, load object (Your Xara eps file).

Here's a glass mug I modeled in Wings3d, render is with C4D CE... still needs some work...I will put the time it would take to tweak this into another glass project instead... hope ya like it anyways... http://www.talkgraphics.com/images/smilies/smile.gif

I like it gidgit, and the chess set too.
I'm gonna have to give the chess set a try. http://www.talkgraphics.com/images/smilies/biggrin.gif

Hi Mike... thanks http://www.talkgraphics.com/images/smilies/smile.gif

Alright, I look forward to checking it out Mike... http://www.talkgraphics.com/images/smilies/smile.gif

here is a mug, slightly tinted green... this is about as far as I could go with color tinting before the reflections really come into play...

Bill - 200% improvement! Looks great!

Teknal - Like Mike said, just make sure you save in AI v9. And you can use the main menu's File --> Merge to add it to your current scene.

gidgit - Good looking mug, I like the green colored one.

Thanks Randy... http://www.talkgraphics.com/images/smilies/smile.gif

I agreee Bill, that looks really nice... your glass has improved over the first by a longshot http://www.talkgraphics.com/images/smilies/smile.gif

Well, here's my final one for this segment of glass anyways... it's just a clear glass but slightly adjusted...

@Mike - Thanks, it works! http://www.talkgraphics.com/images/smilies/smile.gif

@gidgit - I like this last one, you can see the inside bottom on the opposite side, on your first scene you couldn't see it very well.

-T

Thanks Mike, yes it is a palm tree. Actually it's a reflection map that Gary Bouton posted here some time back, or was it in one of his TrueSpace tutorials.

Thanks TekNal. As Mike and Randy said, export from Xara as ai/eps.

Thanks Randy. Your advice on the specular and reflection worked great.

Thanks Gidgit. Great looking chess set and the glass got better with each post.

thanks guys... this was fun, almost felt like I was in class with you... everybody having a good time and improving along the way... http://www.talkgraphics.com/images/smilies/biggrin.gif

Actualy, I must confess hehe, I showed Stu my first one and he says " looks good James... cough, raise the refraction, cough cough " http://www.talkgraphics.com/images/smilies/biggrin.gif He's such a funny guy... http://www.talkgraphics.com/images/smilies/biggrin.gif

and so I did... also, ... slightly changing the angle of the cam, and.. I got a far better result.... hmmm, cool http://www.talkgraphics.com/images/smilies/biggrin.gif

If any are interested...


color... a medium dark green @ 100 %

transparency... white @ 100%, fresnel, refraction @ 1.55

reflection... white @ 100%

specular... plastic, width @ 6%, hieght @ 100 %


and when I tinted this, basically all that was done...from the clear glass... was changing the transparency color to a very light green, ( transparency color r232,g255,b243 @ 100 % )

wow, amazing that just changing this one color so slightly can effect the overall tint of the glass so much... I just tried this green tint with the 1.55 refraction and it looks pretty decent... http://www.talkgraphics.com/images/smilies/smile.gif

Hope this is some help to any... I mean it isn't perfect, but, with the right tweaks, cam angles, lights, scene, etc.... I mean go nuts eh... maybe some of you will find a new set of settings from this which you would kindly share with us and we will get better and better http://www.talkgraphics.com/images/smilies/smile.gif

oh, and btw, that was a great tip re the ai import Mike... thanks eh http://www.talkgraphics.com/images/smilies/smile.gif

Nice stuff here guys. Her's a couple of things I have been playing with, combined. C4D model and render. C&C welcome.

Arnold

Nice one Arnold, I like the silver chess pieces too. http://www.talkgraphics.com/images/smilies/biggrin.gif

I agree with Mike... cool http://www.talkgraphics.com/images/smilies/smile.gif

@Arnold, cool bottle. Took me a while to realize it was solid up top, was trying to find the closer rim then realized it was closed, looks like someone captured that chess piece in the bottle.

@gidgit, I found a site that says the refraction index for glass is 1.517. I punched that into a scene that has been rendering for almost 15 hours now and probably has another 8 to go. But it is looking very nice so far, the glass looks great in it. I probably upped the number of rays, etc. way too high for what I needed to get a nice look but I'm not stopping the render now...I'll post it here as soon as it's done.

Here's the site I found about refraction and has refraction indexes for different materials.

http://www.geocities.com/thesciencef...efraction.html


I remember reading a Bryce related site I think that had much more info on refraction index and more materials listed. I'll see if I can find that link later. Stuff is way over my head as far as the math goes but the numbers for glass seem to make it look real. http://www.talkgraphics.com/images/smilies/biggrin.gif

-Tek

fossman - Great looking glass, love the bevels.

Hi Arnold,

Great glass! I like how you positioned it inverted over the chess piece. Very nice modeling on all the pieces.

Hey Teknal... thanx for that info... indeed, the math is a tad beyond my meager brainpower as well http://www.talkgraphics.com/images/smilies/wink.gif http://www.talkgraphics.com/images/smilies/biggrin.gif

Ya know what, I tell you we were really close with the 1.55 setting even though eh...

and yes, I would love to view more info on this subject.. so please post such whenever ya find it http://www.talkgraphics.com/images/smilies/smile.gif

Thanks again for sharing this information, it was fun to test them all out because of this info http://www.talkgraphics.com/images/smilies/smile.gif


here's a pic with three different settings... 1.5, 1.517, and 1.55... but not in that exact order http://www.talkgraphics.com/images/smilies/wink.gif

Look closely and you can barely tell the difference... and when you do see the subtle difference maybe you can tell just which pic is which setting... try out your hand guys... which setting belongs to left, center and right glass here..

I would also be interested in viewing if anybody else would care to do this sort of test with these three settings... http://www.talkgraphics.com/images/smilies/smile.gif

Thanks for your comments guy's, I appreciate it.
Don't get much time to do these things, so it's nice to get comments once in a while.

Arnold

Hard for me to tell but I will go for this.

1.55, 1.517, 1.5

Very hard to tell any difference. But I'm guessing it's 1.55, 1.5, 1.517

Arnold, Thanks to you for sharing your image. Gives us that push to try and get close to your level.

I totaly agree with Bill on this Anold http://www.talkgraphics.com/images/smilies/smile.gif

ok, the answer is.... 1.5,1.55, 1.517...

so from this I am guessing that anywher near 1.5 is cool for glass... though as I have suggested, it would be very cool to see if this theory stands up with other glass objects under different lighting conditions, and perhaps even with different cam angles as well... http://www.talkgraphics.com/images/smilies/smile.gif

anybody game to give this a go?

<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR> ok, the answer is.... 1.5,1.55, 1.517... <HR></BLOCKQUOTE>

Huh! ....what was the question??????

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

@gidgit - I can't really detect any difference between the images you have posted. I was merely pointing out what the glass index was. http://www.talkgraphics.com/images/smilies/smile.gif It would be an interesting experiment to try different object and settings to see how it looks. Maybe after class is over. http://www.talkgraphics.com/images/smilies/smile.gif

My image is done rendering, it took 22:03:45. I turned the Ray & Reflection depths up. Anyway, the glass is made from one Loft Nurb. Now I just have to finish the other parts of my assignment tomorrow night!

-Tek

haha, Mike, you are a card http://www.talkgraphics.com/images/smilies/biggrin.gif

Teknal... np's, I really did appreciate the information... cause I really didn't know such, and it was a good number to base this quick test from... http://www.talkgraphics.com/images/smilies/smile.gif and yes, I would surely be interested in doing up more tests whenever you have time so as we could compare notes... really facinating stuff for sure http://www.talkgraphics.com/images/smilies/smile.gif

Holy cow... you are a one man C4D experience here... very cool piece... http://www.talkgraphics.com/images/smilies/smile.gif

22 hours... yikes... What are your machine specs if you don't mind me enquiring?

@gidgit - Thanks http://www.talkgraphics.com/images/smilies/smile.gif My specs are win2k pro running on a system I put together the year before last if I remember correctly. It has an AMD XP 1800+ cpu and an Asus A7V333 motherboard with 1GB of ram. I think I can't go up past 2400 on the cpu because I have rev.1 of the motherboard with the lower fsb where rev.2 could use the next cpus that came out after mine. Money is so tight right now but hopefully I can upgrade to something faster in the next 6-8 months. http://www.talkgraphics.com/images/smilies/biggrin.gif

As a point of reference the refraction index on my glass for this vase was set at 1.52

Arnold

@ Teknal... thanx for the specs... wow, that's a pretty quick machine you already have... I knows what ya mean about the expence involved... I just went from a 400 celeron to a amd 2200+ last month... http://www.talkgraphics.com/images/smilies/smile.gif and yes, I too look forward to upgrading asap http://www.talkgraphics.com/images/smilies/biggrin.gif

Hey thanks Arnold... wow, that really looks nice... 1.52 duly noted http://www.talkgraphics.com/images/smilies/smile.gif

hey, would you care to share with us on just how you went about creating that beautiful vase... particularly the detailing along the sides ... http://www.talkgraphics.com/images/smilies/smile.gif http://www.talkgraphics.com/images/smilies/smile.gif

Finally got some time to play with C4D and the refraction for glass. A simple loft nurbs glass made with circle-rings. One Omni light source. Refractions as noted in the image.

haha, right on Bill... gee, so close eh... I mean for what ever little difference there is, I seriously doubt it would make any difference at all within the grande scheme of things...

Thanks for posting this test result Bill http://www.talkgraphics.com/images/smilies/smile.gif
