• Material library, BRDF/BDTF - (Optional) This data characterizes exactly how light scatters from real materials upon reflection and refraction. The General Materials Library includes over 180 materials such as semi-specular aluminum, hammertone and textured aluminum and various paints. The library of measured data means you don't have to guess at material scattering properties. You simply pick your material from the list and get an accurate simulation. The data is measured in our custom-built measurement device allowing us to add new materials as they become available and measure special materials for our customers as a service.
• Lamp library - Photopia includes a library of more than 300 lamps commonly used in the architectural and entertainment industries. The lamp models include the true geometry of the physical lamps as well as their photometric characteristics. You may also construct your own lamp models or use LTI Optics' lamp construction service. See our technical paper for more information on lamp models.
Libraries are updated on a regular basis by adding new lamp and material models about every month. Customers with a maintenance or ADUP contract can download these libraries for free.
