New rendering engine: V-Ray

New DomuS3D® release, coded Pegasus, doubles the rendering power siding the new rendering engine V-Ray to the experienced mental ray®

DomuS3D® Pegasus allows you to choose between the most powerful and professional rendering engines in the world. Together with mental ray®, in fact, now it is possible to use V-Ray when rendering the scenes. When you purchase the Professional license, you can choose one of the engines (V-Ray is the default one, if not differently requested). If you want to add the second one, you have to order it separately. Compared with mental ray®, V-Ray differs in:

  • Simplicity: even if the rendering process involves so many variables and parameters, V-Ray is equipped with automatic algorithms that allow users to easily get photographic images of the scene. Presets (low, medium and high quality) together with the automatic exposure system make easier for the user to engage the rendering process eve if he/she is not expert in rendering techniques.
    Same as with digital cameras, if you want to get a good result you have to avoid backlight and overexposed areas; usually it is enough to take care that the sun does not enter the scene in front of the observer. Here’s an example of a rendering made with the automatic exposure algorithm.
    After the first rendering image made with the automatic exposure algorithm, you can setup the scene parameters starting from the setup the Engine has found for you; as a result, you’ll save time in order to setup the scene’s parameters prior launching the rendering.
  • Rendering speed: benchmarks made in the test period report that, with the same computers, projects and materials in the scene, V-Ray is quicker in generating the rendering images.
  • Displacement: V-Ray offers the same bump mappings as mental ray®, plus the displacement option, which is typical for materials that have a thickness or relief, such as stone... With V-Ray, you can start creating 3D tiles still planning them with the simplicity of 2D images.
  • Rendering usgin GPU: the V-Ray standard engine uses the internal CPU for the rendering process. You can decide, indeed, to use V-Ray RT engine (RT means Real Time, and is equipped with the standard one) in order to be able to use GPU for rendering. AS you know, GPU is dramatically quicker than CPU, hence having fast NVIDIA graphic cards may result in smaller rendering times (for more information refer to chapter 5).
    As the Real Time engine lives in a dedicated window, you can:
    - Keep on working on the project while V-Ray RT creates the rendering image
    - Open the RT window on a second monitor, so that the customer keeps on looking at the rendering, while the designer concentrates on project variations
  • Distributed rendering: this module allows you to split the rendering process over multiple computers over the LAN, but can be used only through the Render Manager application. Refer to Chapter 5 in order to know how to use the distributed rendering.
