Project: Watch

This scene makes use of the Stochastic Progressive Photon Mapping (SPPM) and height mapping capabilities of LuxRender 1.3.1 to generate a "realistic looking" advertisement for a watch.

 

Measuring in at over 11 million polygons, each frame takes nearly an hour to render at 1600x1200 pixels. The post processing consists of minor adjustments to contrast and vibrance, applied in Photoshop CS2.

By using LuxRender's built in film simulation profiles, I was able to easily generate a few different color selections for this angle.

 

The image above uses the Advantix 100 film response profile, while the image at right makes use of the Agfapan APX 400 black and white profile.

 

Film profiles alter the contrast, saturation, white balance, and overall levels when applied, mimicking the color response of the actual film.

In addition to the above views, I composed and rendered a number of "product-shot" style angles, with a metal rather than leather band. Making use of SPPM, the high-gloss metal and mirror effect on the ground had minimal effect on the render times.

 

The image at left was rendered to 2,000 passes per pixel in about 2 hours. The final result is extremely well converged, and has only a very small amount of visible noise even after sharpening.

The images above show, from left to right, the modelling of the watch, the lighting setup for the "product-shot" style renders, and finally the image being rendered in LuxRender's GUI. The system used to render the images consists of 56 threads running at 3.0 GHz, and 128 gigabytes of RAM. Blender 2.69 and LuxRender 1.3.1 are pictured running under Windows XP Professional 64-bit.

This project was completed on 1 August 2021.
