Photorealistic rendering – CAD software developer chooses Siemens solution for optimal visualizations

Cadalog Inc. develops and sells CAD (Computer-aided Design) software for the global market, particularly Asia.

For architects and interior designers, photorealistic images are very important when presenting their designs to customers. The rooms and buildings in the visualization should be as true-to-life as possible. This was why Cadalog developed the SU Podium plugin for SketchUp architecture software: a CPU (Central Processing Unit)-based solution. For complex animations, Cadalog also designed the PodiumWalker plugin in response to customer requests. However, Cadalog was not satisfied with the quality of the visualization, particularly in terms of the lighting. In order to meet these demands, David Wayne, Chief Executive Officer (CEO) of Cadalog, turned to Lightworks. 

In addition to complete proprietary software solutions, Cadalog also offers plugins such as SU Podium for SketchUp visualization software, for example.

Mastering light and shadows

The Lightworks portfolio includes the Iray+ software development kit. Lightworks supported Cadalog in the integration of this SDK, which renders on graphics cards (GPUs). Following the integration of Iray+ in Cadalog software, Cadalog developed the new ProWalker plugin, which can be integrated into existing customer solutions without problems. ProWalker makes it possible to create high-level photorealistic visualizations, in part through the use of MDL (a programming language for defining physically based materials). The quality, aesthetics and interactivity of the visualization were improved considerably, as can be seen clearly in a direct comparison of the old and new solution. Thanks to Iray+, Cadalog is finally able to provide its customers with a high-quality solution that is easy to use and meets the company's own quality expectations for a modern visualization.

Cadalog wants visualizations to be as photorealistic as possible, especially in terms of light and shadow distribution. In order to create complex animations and high-quality visualizations, Cadalog chose Iray+ rendering software from the Siemens PLM Software NX portfolio when developing the new ProWalker plugin.
