![]() Geometry ConversionĪs shown, a BRL-CAD target description can be converted to a finite element mesh (FEM) using the BRL-CAD g-sat exporter and Cubit from Sandia National Laboratories. The bearing is modeled with a material appearance resembling acrylic glass, and this raytracing result shows reflection, refraction, shadowing, and some caustic effects. The image shown is a BRL-CAD 2D framebuffer screenshot displaying the rendering of a ball bearing. Raytracing is central to BRL-CAD as a means for performing geometric analysis (e.g., calculating weights and moments of inertia) and for rendering images for visualization purposes. This model was created by students new to BRL-CAD in the span of about 2 weeks, starting from actual measurements in a museum. Shown is a 3D model of a Goliath tracked mine, a German-engineered remote controlled vehicle used during World War II. Solid modeling is distinguished from other forms of geometric modeling by an emphasis on being physically accurate, fully describing 3D space. Solid GeometryīRL-CAD focuses on solid modeling CAD. Let's take a quick look at just some of the high-level features provided by BRL-CAD. One strength of a solid modeling system with integrated high-performance rendering is the ability to showcase some of those features graphically. ![]() BRL-CAD has thousands of distinct features that have been developed over a number of decades.
