4 PREFERENCES» Sim2 HDR» Luminance Mapping: Sets the luminance mapping for the Sim2HDR display if photometricparameters are enabled. A value of 1 maps a luminance value of 1 cd/m 2in the rendering to a value of 1 cd/m 2 on the Sim2HDR display.4.14.3 Raytracing Quality» Illumination Mode Sets the default lighting mode for materials for interactiveand still frame antialiasing.» Precomputed Illumination: The precomputed illumination mode is comparableto VRED OpenGL rendering mode. It uses precomputed ambient occlusion andindirect illumination for rendering and calculates specular reflections and refractionsand correct shadows from lightsources.» Precomputed + Shadows: The Precomputed + Shadows Mode uses precomputedimage based lighting and indirect illumination but doesn’t use precomputedAmbient Occlusion values. Instead it calculates shadows based on the active environment.» Precomputed + IBL: The new Precomputed + IBL Mode uses precomputed indirectillumination and samples the environment. It replaces the old Fast GlobalIllumination mode.» Full Global Illumination: The Full Global Illumination Mode doesn’t use any precomputedvalues but accurately samples everything in a physically based approach.Note that other features like Photon Mapping require the rendermode to be setto Full Global Illumination.» Photon Tracing Photon Tracing provides an approach to calculate the global illuminationin a scene. The default full global illumination mode in VRED provideshigh quality results but may require longer calculation times. Photon Tracing canreduce the time required to render a clean image by a larger margin, especiallyin indoor scenarios like car interieurs or architectural indoor scenes. VRED providesdifferent Photon mapping modes.60
