\"\"<\/a>I’ve been looking for some vector (3D) primitives in Java. I was hoping to find an existing library (something like blitz<\/a> or tnt<\/a> in c++). So far no luck so it looks as if I’ll wind up writing those I need myself.<\/p>\n

Shouldn’t be too bad really. Mostly looking for things like dot product, cross product and some matrix multiplies in floating point. I did find pieces here and there, but none of the libraries I came across has the full set and since everyone implements their own point, matrix and vector classes, they don’t play well together.<\/p>\n

The pieces I need shouldn’t take all that long to write and test so I’m going to go that way. Not looking for anything attached to 3D rendering, just need to work with some geometry in three-space and get some results. In the end, probably not a bad exercise.<\/p>\n","protected":false},"excerpt":{"rendered":"
