WebGL Caustics

E-mail

Good news: I'm not dead! I know it's been awfully quiet on my website for a long time, but now I finally have something to share again:

I've been working on a WebGL graphic demo about realtime caustics. The project is already complete and you can find the link further down in this post.

The realtime criteria may only hold for low quality settings, but it's still very fast. Also the caustics are not 100% physically accurate. However, with some extreme settings, you can get suprisingly good results. Here are some comparisons to LuxRender:

 

You can increase the accuracy by increasing the Sample Falloff and Sample Area, but it also slightly increases the noise. More influence on the noise and the performance has the number of Caustic Samples.

Later I might also release the project documentation (in german). The application itself can be found here:

Just a little standard disclaimer:
This software is provided 'as-is', without any express or implied warranty. In no event will the authors be held liable for any damages arising from the use of this software.

Compatibility has only been confirmed for Firefox so far. If you use a different browser, I would be happy to get some feedback.

That all being said: Have fun trying it out!

Whats next: I was in Japan over new year and will probably release a quite few photographs on deviantArt in the coming weeks. I have also two small game projects, which are still open. But those won't be finished soon. I'd also like to do some blendering, but I'm afraid I have as little time as ever.

Cycles Render Tests

E-mail

Of course I had to do some tests with the new Cycles render engine, too. I didn't intend to create photorealism, I just wanted to see how my "usual" animations would look like with Cycles.
Those files have been on my computer for some weeks now... Sorry for not posting them earlier. It's just that my time is very limited at moment.

First of all I think I should also mention, that the .blend File of the Energy Generator animation is now also available for download: Link

But now lets get to the Cycles tests: This is what happens, when you try to do my usual particle animations with Cycles (a fluid animation is also included):

Dim lights

Is it just me or is the youtube quality getting worse?
Anyway... You remember the Dispersion Effect I created with Blender? Well, this it what it could look like, when rendered with Cycles (+ more color samples, inculding violet + a higher refraction index):

 

The last experiment is a short animation loop in Stereo 3D using Blender Cycles and Flash (click on the thumbnail to get to the animation):

You will need red/cyan glasses to see the Stereo 3D effect.

Drawing stereo images by hand

E-mail

Some days ago I tried to draw a stereoscopic image by hand. I wouldn't consider it to be something special, but the technique I used might be interesting: Link

In order to view the image correctly, cross your eyes until both pictures overlap.

 

More Photographs

E-mail

I've been uploading quite a lot of photographs on deviantArt lately. I know my website has been mostly about Blender related things up until now. So I guess you don't expect me to post news about photographs all the time. Rest assured, I think not every of my photographs is worth to be mentioned in a news entry. However there are two new (slightly manipulated) photographs, which I think really deserve to be emphasized:

Wouldn't you agree?

 

The Contact Form has been removed

E-mail

A small update regarding my website: I removed the contact form from the main menu. You can still reach me directly using the E-Mail address in the impressum. The impressum can now be found in the drop down menu of the menu item "About" (it was previously a drop down of contact).

Why did I remove it? Roughly 90% of the mails that were send by the contact from, were spam mails.
