LightTools 5.3 High-Speed Photorealistic Rendering Engine

PASADENA, Calif., June 9, 2006 -- A high-speed photorealistic rendering engine is a standard part of LightTools Version 5.3 software from Optical Research Associates (ORA). This enables a designer to generate high-quality images of LightTools models that appear to be digital photographs. Users can apply surface finishes from an extensive built-in library and set backgrounds.

ltools2.jpgA key aspect of the LightTools photorealistic renderer is its ability to include lit appearance -- that is, to show the luminance effects of light sources contained within the model itself. These photorealistic views can be produced in any aspect ratio, with resolution limited only by system memory, and saved in standard graphics file formats, including PNG, BMP, JPG and TIFF, as well as high dynamic-range formats such as HDR and OpenEXR.

ltools1.jpgLightTools Version 5.3 also allows a user to create extremely complex three-dimensional objects through a "skinned solids" feature that enables a user to build an object simply by specifying its transverse cross-sections -- available in various shapes -- at two or more points. The software then automatically constructs the longitudinal structure between these shapes. A user can also specify the longitudinal surface profile to be straight lines, cubic splines or even Bezier curves. The precise shape of the skinned solids can then be adjusted automatically using the LightTools optimizer.

The speed at which LightTools performs complex photometric analyses and system optimization has been improved with the addition of multi-CPU support, available to all users in this release as a beta feature. Specifically, LightTools can now make full use of hardware configurations involving multiple CPUs, or single CPUs with hyperthreading or dual core architecture. The LightTools multi-CPU capability supports up to eight processors in a single PC and is available at no extra cost.
