V-Ray

From Wikipedia, the free encyclopedia

V-ray is 3d graphics rendering software created by Chaos Group.

It is available as a plugin for 3d studio max and will be released as a plugin for Maya in the second quarter of 2007. A standalone version is scheduled at that time also. It supports 32bit and 64bit. It main features are unparalleled speed as it is considered the fastest photorealistic rendering solution. It is considered providing unmatched quality at the fraction of cost of other high end renderers like Mental Ray or Pixar's PRMan. Has been used extensively in feature film productions, multi-million dollar game productions and huge and small architectural visualizations projects.

[edit] Main Features

[edit] I. Architecture

(*) Object-oriented API
(*) Fully multithreaded, supports multi processor, multi core and hyperthreading
(*) Unified random quasi-Monte Carlo sampling system
(*) Distributed rendering
(*) Efficient shading system specifically optimized for ray-tracing

[edit] II. Geometry

(*) Efficient geometry handling ( 2 engines, static and dynamic )
(*) On-demand geometry creation
(*) On-demand geometry loading from disk files
(*) Displacement mapping
(*) Catmull-Clark and Loop subdivision surfaces
(*) Extensible with custom geometric primitives through the V-Ray SDK

[edit] III. Image sampling

(*) Different sampling methods (4)
(*) Full-scene antialiasing.
(*) Progressive path tracing.
(*) Support for additional 30 render elements (diffuse, reflection, GI etc).

[edit] IV. Illumination

(*) Physically accurate full global illumination solutions
(*) 4 different GI algorithms: path tracing, irradiance cache, photon maps, light cache.
(*) Reusable GI solutions for accelerated rendering of walk-through animations.
(*) Physically accurate area lights.
(*) Extensible with custom lights through the V-Ray SDK.

[edit] V. Shaders

(*) Advanced material
(*) Blurry reflections/refractions
(*) Accurate highlights
(*) Sub-surface scattering
(*) Extensible with custom sharers through the V-Ray SDK

[edit] VI. Camera effects

(*) Physically accurate depth-of-field with bokeh effects
(*) Physically accurate motion blur
(*) Extensible with custom cameras through the V-Ray SDK

[edit] VII. Extras

(*) Toon effect
(*) Fur generator
(*) Extended matte/shadow capabilities
(*) Support for Render-to-Texture mode of 3dsmax

[edit] VIII. Frame buffer

(*) V-Ray specific frame buffer with integrated color corrections and display of multiple rendering elements.
(*) Direct rendering to disk for extremely large images ( up to 10000000x100000000 )Rendered images can be converted to OpenEXR files or imported back into 3dsmax.
