Lightwave IBL Test -01

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.
