COMITS-Ray

COMITS-Ray

Iray SDK

• Accomplished in 2012 via the NVIDIA Iray SDK

• See GTC 2015 talk by Martin-Karl Lefrancois

• Bringing Physical Based Rendering To Your Application



What is Iray?

■ Physically based push button rendering solution (Path Tracing)

■ Multiple rendering modes for interactive to final frame workflows

■ One unified Material Definition Language (MDL)

■ Cluster and cloud rendering that scales with more GPUs● Scales very well on NVIDIA Visual Computing Appliance (VCA)

Render a video in 2 days vs 1 month (utilizing 3 VCAs)



COMITS-Ray

■ Physics Based Rendering (PBR)

● A very accurate physics-based simulation of light propagation

through a 3D environment

● How will it look?

• Four factors determine that
