BRL-CAD currently has only very basic labels that are attached to CSG primitive parameters in 3D wireframe views. We need much more than that - modern systems typically show a variety of leader line and text graphics that illustrate information associated with 3D geometry. There are two aspects to this task - one is to create an "annotation primitive" in BRL-CAD that can hold this information, and the other is to display that information in the 3D view. The second depends on the first - "hacking in" a 3D text and leader-line display won't get us what we need.



  • Familiarity with C/C++
  • (For graphical components) familiarity with OpenGL + Text
