Session Highlights:

- Predict lighting levels in a scene lit with daylight or electric light
- Find correct values of reflectance and transmittance for the building materials you create and use these values in a lighting render of an existing building

- Import and use the correct photometric information for a particular manufacturer's light fitting
- Determine the most appropriate renderer for a lighting-analysis task
- Build a quality-control process in your own office that provides quality assurance for the predictions of lighting levels in renders

DV204-1 Simulating Reality: Daylight and Lighting in Architecture with Autodesk® VIZ

Can physically based lighting simulations be trusted to simulate real lighting? Using practical examples of day-lit museums, we will work through how Autodesk VIZ can use lighting physics to predict light levels in a building. We?ll help decipher lighting jargon, such as ?colorspaces,? ?reflectances,? ?BRDFs,? and ?BTDFs?, and terms like ?luminance? and ?intensity.? Computer renderers like mental ray and Radiosity, plus renderers in Autodesk 3ds Max and Autodesk VIZ, have started to use the physics of light to represent in the digital world the flow of light in the physical world. The reason? Render results are easier to understand. Globally illuminated pictures certainly look good. But do they predict light levels accurately -- and can their output be trusted?
