High-performance Rendering Using the Supercomputer
One of the areas where massive exploitation of HPC occurs is the computer graphics, particularly synthesis of image or rendering of virtual scenes. Rendering has many practical areas of application, e.g. in mechanical engineering, industrial design, or entertainment industry.
To speed up the rendering process, it is possible to use not only graphic accelerators but also co-processors. The new Intel Xeon Phi co-processor contains more than 60 cores and in cooperation with CPU it can reach, in many cases, multiple accelerations. This acceleration is also possible to be reached on Salomon supercomputer, where porting Blender Cycles, the freeware rendering system, on MIC co-processors has been made possible.
The IT4I R&D team has also participated in the rendering of Cosmos Laundromat, an open film, (https://www.youtube.com/watch?v=Y-rmzh0PI3c).
Supported Rendering Engines
Blender Internal 2.69 (GPL license)
Blender Internal is a basic rendering engine of Blender, a freeware 3D animating tool.
Cycles Render (APL2 license)
Cycles rendering engine has already been a part of Blender since Blender 2.61 version. Computations can be accelerated by graphics cards with CUDA technology and Intel Xeon Phi co-processors (MIC). This rendering tool implements Quasi Monte Carlo method with Sobol generator for global illumination computation.
LuxRender 1.3.1 (APL2 license)
LuxRender is a freeware rendering system using Monte Carlo method and Metropolis-Hastings algorithm (Metropolis light transport method) for rendering the equation computation. It is supported by OpenCL graphics cards. 3D applications a scene can be exported from to LuxRender: Blender 2.6x, Carrara, 3dsmax, Sketchup, Cinema 4D, DAZ Studio, Autodesk Softimage, Poser.
Maxwell Render Suite V3 (komerční licence)
Maxwell is a rendering engine based on Metropolis light transport method. All parts of Maxwell, such as light emitters, materials, shaders, cameras etc., are based on physical models. Maxwell supports these platforms: 3dsmax , ArchiCAD, Autodesk VIZ, Autodesk Softimage, Bonzai3D, Cinema 4D, FormZ, Houdini, Lightwave, Maya, Microstation, Modo, Revit , Rhinoceros, Sketchup, SolidWorks, Nuke, Photoshop, After Effects, Allplan, SolidThinking, Blender.
