Abstract

For 3D scene simulation in IR we have to obtain the distribution of radiation in a scene, which consists of thermal emission and its reflections. The thermal emission follows the temperature, which can be calculated by the thermal modelling software RadThermIR. Furthermore, the builtin radiosity algorithm of this program can also treat the Lambertian reflections in the scene. The rest of the existent radiation is determined by a raytracer. In this talk I will explain how to set up a suitable combination of radiosity and raytracing, what extensions to RadThermIR are necessary, how radiosity calculations in large scenes can be accelerated by clustering, and how to embed all of that into the simulation workflow.
