Project Description

This project supports the continued development of DIRSIG, through the ground-up rewrite of version 5, to meet the needs of the user community. Prior work focused on the development of a core radiometry capability with processing efficiency to meet modern requirements in an open, flexible framework. Project development exploited the new interface to enable runtime control of scene objects such as secondary sources (street lights, headlights, etc..), scene dynamics, voxelization and truth collection. Additional work supported the maintenance and documentation of capabilities.

Project Status:

Advances made under this project enabled the development of corollary tools, such as the chip maker (plugin-based generation of “chip sets” for artificial intelligence training), and new capabilities, such as the direct viewing of primary sources. Improvements to runtime efficiency resulted in 25-150% speedup improvements on standard scenes.
