Ray Tracing

The Ray Tracing options let you customize the Stellar Physically Correct engine.

This page discusses:

Static/Dynamic Mode Handling

Dynamic Mode
Lets you configure how the Stellar Physically Correct and the Stellar Realtime Native engines interact with each other.

Select the engine to be used in dynamic mode:

  • Rasterizer means that you use the Stellar Realtime Native engine.
  • Global illumination means that you use the Stellar Physically Correct engine.

Transition Frames
Lets you define the number of transition frames used to make the transition from dynamic to static mode as smooth as possible.

Local Configuration

Compute Hardware
Lets you select the hardware on which ray tracing computations are executed.

Distributed Configuration

Enable distributed rendering
Lets you use a computer cluster for ray tracing from CPUs. This enables performance enhancement.
Cluster host name
Specifies the host name of the head node of the cluster used for ray tracing.
Cluster port
Specifies the port where to access the cluster.
Local host name
Lets you specify the listening interface used by the 3DEXPERIENCE platform when connecting to the cluster.
Enable compression
Enable compression of the rendered image coming from the cluster.
Compression ratio
Specifies the level of compression used.

A low level allows better data compression and thus improves performance (in terms of FPS) during camera movement or during object manipulation, but this might impact image quality.
