I'm a relatively new user of BRL-CAD and I'm trying to do something it may not even support. Specifically, I wish to find the intersection surface of two other surfaces, which may not be watertight solids. I realize that, in general, this is an intractable problem, but I can live with certain cases failing. All surfaces are triangulated (BOTs), and have vertex and face normals. I have certain other geometric guarantees, but they're probably not germane right now.
I'm using BRL-CAD as a set of libraries which are called from another program. Using the sample code provided with the distribution, I've managed to cobble together some code that imports OBJ files, performs boolean operations on them, and spits out the results as OBJ files. I can post this code here, or on a website, if looking at it will help, or I can go into greater detail about how I'm constructing the regions, etc. that I'm feeding into the mk_addmember function (to do the boolean). Any advice? Or is BRL-CAD just not written to deal well with non- watertight solids at all? -Jeff ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
