LightTools 5.4 Beta Delivers User-Defined 3D Textures for Advanced Illumination Modeling

LightTools User-Defined 3D Textures |
August 2006 - LightTools Version 5.4 Beta, available to all users, delivers a powerful and flexible user-defined 3D textures capability that enables designers to create arbitrary geometry, save it as a library element, and use it as the basis for texture zones. This feature can be used to model various components of LCD backlights, micro lens arrays, digital micromirror devices (DMDs) for projection systems, and components of light pipes. Designers can create native geometry in LightTools, or import some or all of the geometry from an external CAD package. They can then create a texture that comprises multiple instances of the library element placed in a pattern using any of the existing placement methods, including Bezier, List, and Mesh placement. Because the memory footprint is minimized, millions of textures can be placed on a single surface. Texture elements can be individually displaced, rotated, and scaled, and the constructional parameters of the user-defined texture definition can be changed after placement, allowing optimization of the texture shape using the LightTools Optimization module.
Additionally, LightTools Version 5.4 Beta delivers enhancements to the Optimization module that significantly improve the results designers can obtain using this feature. This includes improvements to the optimization engine that bolster the convergence success rate, and improvements to the merit function results chart that display the results in either a logarithmic or linear scale.
LightTools 5.4 Beta will begin shipping in early September 2006. Try it out now and gain first-hand experience with these innovative features.
