VRay for 3ds Max

Core Architecture

---

• Multi-platform object-oriented API
• Fully multithreaded core
• Unified sampling system based on Schlick sampling
• Distributed rendering
• Efficient shading system specifically optimized for ray-tracing
• Modular architecture – many components of the system can be replaced with custom ones

Geometry

---

• Efficient geometry handling
• True instance rendering
• On-demand dynamic 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

Image sampling

---

• Three different image sampling methods
• Full-scene anti-aliasing
• Progressive path tracing
• Support for additional render elements (diffuse, reflection, GI etc)
• Advanced color (tone) mapping controls
• Extensible with custom image samplers through the V-Ray SDK
