'Simulating Global/indirect Illumination with Mental Ray' lcfX(~/m^

Mental ray, a product of the Mental images, Inc, is the first rendering engine, which simulates the physically correction of the real light and reaction of surfaces to light. Together with Renderman, by PIXAR, mental ray is recognized as an industry-standard rendering software; and has been a major contribution to world-wide design visualization and feature film, including Oscar-awarded winning movie Spider-man for the best visual effect. Mental ray has been integrated into Softimage|3D and Softimage|XSI, Autodesk 3ds max, Alias Maya, Side Effects Software's Houdini 5, SolidWorks PhotoWorks 2, and Dassault Système's CATIA V4, V5 products, only in 3ds Max 6+. In the real world, light energy bounced off from one surface to another, causing some received-light surfaces to be secondary emitted-light ones. That's why illumination would be more even and interesting (in some senses). In 3d graphics, however, it does not happen by default, and users have to tell the software to simulate a system of bounced lighting. There are already two methods of generating this in Max, which are Light Tracer and radiosity. Mental ray is a newly-added one, based on different technology.
Interior scene: (室内场景)
--------------------------------------------------------------------------------
First, download the scene file, then follow me. Open INTERIOR_LIGHT_MAX8.max from the directory. This is an imaginary cartoon-like space which shows a group of teapot trying to hide from the another. The renderer is currently set up to be Default Scanline. Also, the resolution is set up to 400x565 for testing/learning purposes. Lighting system includes one Photometric Area Light.
(场景默认使用扫描线渲染。灯光系统包含一个光度学面积灯。)
1.Hit render (F9) to start evaluating the render.
(F9渲染察看。)
The scene generally looks boring as it is very shadowy and unrealistic.
(现在场景非常阴暗,不真实。) |
