The “conf.h” and “machine.h” are ubiquitous in almost all BRLCAD apps BRL-CAD is a powerful constructive solid geometry solid modeling.See source tree: rt/rtexample.c BRL-CAD User’s Group Meeting 2002.The Big-6 BRL-CAD User’s Group Meeting 2002 What is BRLCAD BRL-CAD is a powerful open source cross-platform solid modeling system that includes interactive geometry editing, high-performance ray-tracing for rendering and geometric analysis, a system performance analysis benchmark suite, geometry libraries for application developers, and more than 30 years of active development.First call is for r1 and second call is for r2. The order of penetration of the ray will be: (start of ray) - c1 - s1 - c2 -> (direction of ray) I expect my ahit callback will be called only twice.
