Overview
Physically based rendering (PBR) simulation produces photorealistic visualisations of products by accurately modelling light–material interactions including reflection, refraction, scattering, and subsurface transport — used for virtual prototyping and design review. Accurate BSDF material modelling combined with HDR environment lighting enables stakeholder sign-off on colour, material, and finish decisions before physical prototypes are available — reducing costly late-stage appearance changes.

Deliverables
Key Aspects
Defining BSDF (Bidirectional Scattering Distribution Function) models for all surface materials — including anisotropic metals, painted plastics, textiles, and glass — to reproduce their real appearance.
Configuring HDR environment lighting, area lights, and sun/sky models to replicate the intended product usage environment — showroom, outdoor, studio, or driving scene.
Computing accurate global illumination including indirect bounce light, colour bleed, and caustic patterns through transparent parts — producing photorealistic scenes indistinguishable from photography.
Generating batches of rendered variants with different colours, materials, and trim options — enabling stakeholder sign-off on appearance before physical prototypes are available.
