Bottle Number Two

Modeling this bottle was a great learning experience. I used several cool tools and features to create it. The etched glass on the front of the bottle is a displacement map made by simply assigning a simple image with an alpha channel to the material and sticking it to the front of the bottle. I am amazed at how well displacement maps work! The real fun, though, was the top closure, which I learned is called a “swing top“. To create it, I used the bezier spline tool with sweep and symmetry nurbs. These powerful tools enabled me to create the complex shapes using exactly NINE points. Incredible!

I grabbed a wine label from the Internet and made a change or two before applying it. As an exercise next time, I’ll have to find the best way to give the labels a tiny bit of thickness, and perhaps an imperfection or two.

The finished render is a bit more subdued than Grant’s photo. It’s a challenge to recreate all of those specular highlights – especially those on the “etched” portion of the bottle, but I’m very pleased with it. 🙂

thedude.com may be the only place you will ever see pink champagne in a white wine bottle with a swing top!

Cinema4D vs. Studio Photography

Inspired by a recent post on Grant’s site, in which he alludes to the many challenges of product photography, I decided to create a challenge for myself. I wanted to see what level of photorealism I could achieve with the Cinema4D Physical Renderer and a few simple 3D objects by recreating Grant’s product shots.

To begin, I intentionally chose the simplest bottle from his series of shots and recreated it in Cinema4D. The bottle and the virtual wine inside are simple splines inside lathe nurbs, meaning they consist of a total of about 20 points spun around or “lathed” into the 3D shapes you see here. The stopper is a couple cylinders with the appropriate materials applied. I’m still a beginner with Cinema4D, so creating the bottle and cork took more than an hour to get just right using Grant’s photo as a guide. I could probably recreate it in 10 minutes now that I have more experience with the bezier curve tool.

(At this point I should thank the Greyscale Gorilla for the awesome tutorials, without which none of this would have been possible. Thank you, Nick and Chris!)

My next thought was to recreate the label exactly, but that quickly morphed into something else. 🙂 The label and foil textures were created from scratch with PhotoShop and a few Custom snowflake shapes from the Symbol palette. Since Cinema4D can use native PSD files with layers an alpha channels intact, this work was easy. I tweaked the PS files and applied the changes in Cinema by simply reloading the modified image. Nice!

The final render was done with the wonderful Cinema4D Physical Renderer. This made it easy to apply a tiny bit of depth of focus to match Grant’s shot. (One of my early renders had the camera focused on the bottle instead of the label, leading to the label being the tiniest bit out of focus. This slight imperfection resulted in perhaps the most realistic-looking render of all. I’m sure there’s a lesson in there somewhere …)

My conclusion is that in some cases, it’s easier and probably cheaper to get great-looking results in the 3D realm than with a camera. Among the many advantages:

  • Infinite depth-of-focus. (Or not.)
  • The ability to render with alpha channels makes post-processing easier.
  • Almost unlimited pixel resolution. Objects can be rendered for the web, for print, film, etc.
  • Objects can easily be rendered with different materials.
  • 3D objects can be rendered on different platforms and with newer, better renderers in the future.
  • 3D objects can be animated.

This is fun. More to come!

aka Kozmo. Grant took this amazingly detailed shot with his new Canon Rebel SL1 and 40mm pancake lens. Sharpalicious!!

Julie shot this panorama with her iPhone. She was, “Driving north from Yellowstone WY toward Livingston MT – looking east.” Beautiful!!

Extreme beauty near Livingston, Montana.

OK – I’ve been feeling kinda bad. My pal Jim visited for a week, and, despite great conversation, great weather and meals at places like Haven, Sea Salt and of course Chop Bar, I took a grand total of one photograph. With a cheap-ass point-and-click. I guess it could have been worse – I could have used a cell phone. There’s no excuse for this.

I was stumped at what to do, and Jim solved the dilemma by posting a really amazing shot of a few of the more than 50 orchids he has blossoming in his kitchen right now. In Madison Wisconsin. In January. I find this amazing. There is absolutely zero chance of me ever being capable of creating anything even remotely like this. I’m in awe.

It was great to hang with you, Dude. Always enlightening in so many ways.
