Glossy dragon in Pisa
This uses one of Paul Debevec's new high-res envirnonment maps (recently uploaded to his website) for lighting.
The glossiness is near the upper limit of what is usable with my renderer before noise due to lack of importance sampling becomes too obvious.
Note that the color of the dragon is actually a neutral grey, but there's a very warm orange light coming from behind!
New Fog Color, ImageBasedLighting and Ambiant Lighting Config with new setting on Level Control Black and White Cutoff with White Level, AFX Contrast and Vibrance, HSL Saturation, Technicolor and Bloom Contrast.

Currently testing on different weather and different places for the main preset, without weatherlist for this moment.

This tea set and tree frog were created using Autodesk Maya 2009 a 3D modeling program. This image was rendered using Mental Ray. The scene was lit by a High Dynamic Range Image. The tree frog was from an earlier project I did.
Level 8 "Menger Sponge" created using recursive instancing (so the memory required by the model is very minimal -- the background image uses far more RAM).
Inspired by seb przd's menger sponge.
Practically indistinguishable at this distance from the level 6 version, and took over twice as long to render...
This 3D model is based on the Mitsubishi Eclipse. The model was created using Autodesk Maya and rendered with Vray. The scene lighting was accomplished with an HDRI and Global illumination.
A first test of image-based lighting in Sunflow using a Structure Synth model of mine. The background is an HDRI pano of a glacier scene.

Model of a Thai statue from the Stanford 3D Scanning Repository. Pretty big with 10,000,000 triangles, but amazingly it's actually a decimated version of an even bigger original with 39 million triangles!

[Tessellation artifacts are a little annoying...]
Rendering using a non-HDR image as a background/light-source.
Despite the light-map not being a HDR image, it seemed to work OK (I guess there'd be slightly better highlights if it was a HDR image).
That's a lot of Buddhas (10,200 of them, to be exact...)!
[Test of instancing: the Buddha model has 1,087,716 polygons, so the total number of "virtual polygons" is 11,094,703,200. Yow!]
This is a sphereflake using nested instancing to depth 6.
The fractal nature is even more obvious than the previous version, but for some reason there doesn't seem to be any clear focal plane... I'm not sure whether the focus is just messed up or it's the very small spheres sort of making everything fuzzy...
blah blah dragon, buddha, ...

IBL : Image Based Lighting...
A CGI rendering technique that allows the use of a 360-degree HDR panoramic-image to provide an omni-directional lighting solution for 3D models.
The goal, when applied in conjunction with Global Illumination rendering, is to try to make the models in a CG scene seamlessly and realistically blend with a photographic background using the lighting characteristics of the illuminating image.
----------------------------------------------------------------------------------------------------------------------------------------
In this scene, the cube, sphere and “tabletop” were 3D models. The background was an HDR panoramic image mapped onto a large sphere that encompassed the entire scene. That's what provided both the illumination and reflection elements to said objects.
Once rendered, I moved the 32-bit Tiff image into PhotoShop, used the alpha matte to extract a selection mask, and blurred the BG to create a shallower DOF.
Easy-Peasy! The whole process took less than 15 minutes to build, render, and comp.
Created in Lightwave 9.6.

This environment map is inside the famous Ennis House. It's another one of Paul Debevec's new hi-res HDR maps (this particular envmap is massive -- it occupies 235 MB of RAM when unpacked during rendering!).
I also made a low-quality (and kinda lame) animation of this scene.
This 3D model is based on the Mitsubishi Eclipse. The model was created using Autodesk Maya and rendered with Vray. The scene lighting was accomplished with an HDRI and Global illumination.
Just testing out the image-based lighting capabilities of Sunflow. Here is the same scene file rendered with different high dynamic range IBL lighting maps. Be sure to check it out at full size. [N.B.: I only used a sample of 200 in Sunflow for the IBL light, which produced a few artifacts in the shadows, I think.]

Hmm, this sort of has a holiday feel... yeah...
~Happy New Year~

Shiny and blue.
So shiny, in fact, that you can see the quantization of the lighting map (much lower res than the environment map)... :-)
(The lack of indirect illumination is also rather obvious, e.g. on the underside of the jaw)

This is a comparison between my knife rendered with some spotlights and the knife rendered with HDRI lighting.
Re-rendering of previous image, using better algorithms (importance sampling).
