Desktop Engineering interviews Paul Sagar, PTC’s director of product management, and representatives from Autodesk, Siemens PLM and Dassault Systemes about various CAD software programs and rendering operations.
Sagar points out that while important, photorealistic rendering is not as necessary as real-time rendering. “Users want to feel more immersed in their design and be able to see a product look more realistic.”
In PTC Creo modeling products (Creo Direct and Creo Parametric), you can choose to work in OpenGL-accelerated mode, with shades and reflections turned on. However, this is not a ray-traced mode. In Creo Parametric, you have the option to produce ray-traced still images, but not to work interactively with CAD models. You may also use PTC’s Creo Advanced Rendering Extension to produce ray-traced images. Ray-traced rendering in PTC Creo products are powered by mental ray from mental images, a division of NVIDIA.
