![]() ![]() ![]() Accurate component characteristics to include dimensions, thickness, and materials is desired and achievable with CAD files that include more detail than just surfaces (i.e., non-shrink wrapped source CAD). It's something the BRL-CAD community is working hard on, but it's not something that will be quick. The quality of the resulting BRL-CADTM geometry is highly dependent on the quality of the CAD that is provided. With open source, skillsets vary wildly and coordination, collaboration, and maintenance are a challenge until a project achieves critical mass. CAD modelers coming out of school are only accustomed to multibillion dollar company products that dedicated highly experienced devs to specific user-facing features under dedicated funding lines. BRL-CAD (pronounced be-are-el-cad) is a powerful, cross-platform, open source solid modeling system that includes interactive three-dimensional (3D) solid geometry editing, high-performance ray tracing support for rendering and geometric analysis, network-distributed framebuffer support, image and signal-processing tools, path tracing and. The image shown is the classic computer graphics Utah teapot model prepared for 3D printing and rendered via BRL-CAD ray tracing. There's simply no PR team, and limited bandwidth to provide support to those that don't contribute in kind. BRL-CAD is one of the few 3D solid modeling systems that not only support geometry in boundary representation NURBS format but also provide extensive support for robust solid ray tracing of NURBS geometry. BRL-CAD is a constructive solid geometry (CSG) solid modeling computer-aided design (CAD) system. ![]() In total, BRL-CAD today has more than 500 full-time staff-years of effort invested, more than pretty much all other open source CAD combined. Development is actively funded annually (just not your priorities). Heavily actively used by gov'ts as it has unique features like validated full shotline solid ray tracing - granted, not a feature most know, understand, or care about but absolutely critical to others. BRL-CAD has a very rich and ongoing development history that is not immediately obvious. ![]()
