Re: [brlcad-devel] An Explanation

I am sorry for asking this. I searched sources to get the idea of ray trace but I couldn't. So please give me a source to get the idea of ray trace. You have mentioned that look at view.c and viewedge.c . I failed to find any algorithm of raytrace. please guide me thank you On 16 March 2016 at

Niks, You may want to have a look at https://lists.sourceforge.net/lists/listinfo/brlcad-devel Unsubscribing your e-mail address from a mailing list is something you should do by yourself. Only in very special cases you could ask an administrator. (I'm not an administrator.) Regards,

Re: [brlcad-devel] An Explanation

Sir please correct me if I am wrong So there are three main obstacles that we have to achieve. 1. Identifying the objects (Either polygons or NURBS) separately instead of going into pixels of the image space 2. Mapping the objects with their corresponding location. (I think I don't get this

Re: [brlcad-devel] An Explanation

"use the knowledge inherent in the ray about what object it's returning the pixel from": If you do a ray-trace with BRL-CAD's librt you won't only get back the point where the ray hits an object but this object's name (and some other data) too. "to group pixels into groups based on objects.": Map
