REAL-TIME, SOFTWARE-BASED HYBRID RAY TRACING FOR BATTERY-POWERED COMPUTING DEVICES

摘要

Hybrid ray tracing or reduced computational complexity. Primary rays are used to build-up the image by rasterization technique. Independently, secondary rays, traced for reflections and other photorealistic features, are generated, and traced in the object space of the scene. A dynamic acceleration structure (DAS) and traversal tools are characterized by high object locality, reduced intersection tests and low-cost updates. Coherence is achieved by handling secondary rays with collective origin and collective destinations. The resulting reduced computational complexity enables a software only implementation, without hardware accelerators.
