Hello, i'm curious how tesselation works in BRLCAD. Looking at example rt_*_tess() functions in librt, it seems that first an empty nmg region is created with nmg_mrsv(), then each "point_t vertex" in the primitive is associated with a "struct vertex" using nmg_vertex_gv() and added to the shell using nmg_cmface(). Finally the region is built using the avaliable shells with nmg_region_a(). Are there any more steps to this process that I'm missing?
I'd like to finish implementing rt_sketch_tess(). I already have a method to closely approximate a sketch by a series of point_t, which was used in rt_sketch_surf_area(), so it seems simple enough if the method I described above is correct. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
