Guide – Simulation and calculation – Software

There’s a broad range of applications readily available for light simulation. The application spectrum covers everything from rapidly, quantitative analyses to advanced visualisation techniques. Whether a software program is able to make accurate light simulations is suggested at the manual, which should specify support of worldwide illumination or maybe radiosity and also the Eulumdat or IES format. When it can then the designer is able to incorporate the photometric information with the respective 3D DXF information.


DIALux is a totally free of charge lighting design software for visualisation and also calculation. The system is supplied by the Deutsches Institut für Angewandte Lichttechnik (DIAL – German Institute of Applied Lighting Technology). The DIALux simulation application provides a fast and simple quantitative evaluation of a design and also includes simple 3D & rendering functions. The ULD data structure for the luminaires comprises the 3D geometry of the luminaire, the gentle intensity distribution, along with articles description. The plug in packages of luminaire manufacturers have extra planning data including maintenance factors or maybe UGR values.


Among the available products from Autodesk is definitely the VIZ program, a system for advanced visualisations. The luminaire information for Autodesk VIZ and for 3ds Max add a 3D version of the luminaire. This consists of surface qualities, textures as well as the potential activity of elements (inverse kinematics). Inverse kinematics enables directional luminaires being aimed through a couple of very simple changes. A light simulation needs extra photometric data. Autodesk VIZ as well as 3ds Max enable radiosity computations to produce numerically precise mild simulations.


Radiance is an experienced light simulation software from Berkeley Lab. The wide range of its of calculation and analysis equipment needs extensive knowledge of os’s and shell commands and so, it’s normally used in research institutes and also by extremely specialised companies. Due to the complexity of its, the system isn’t ideal for brief representations of qualitative lighting designs. A physically appropriate light simulation is achievable with IES luminaire information.
