I find myself back again reading the documentation to OpenGL. There are so many cool things that can be done with this stuff. At this point it is a bit like a whole new API though as the programmable pipeline is new since last time I took a serious look. Much more capability, but in many ways a completely different way of making things happen.<\/p>\n
The issues around gimbal lock with Euler angles and transformation matrices (which is the approach I’ve used in the past) are making me seriously look at quaternions again. They’re a bit of a strange hybrid, but it seems as if they offer a means to manage rotations that may have fewer sharp edges than what I’ve used in the past.<\/p>\n
I think I may wind up buying the paper copy of the the OpenGL Superbible<\/a> as it is likely to be more pleasant to flip around in than the kindle version I’ve been reading. Also suspecting that HLSL is important enough that the OpenGL Shading Language<\/a> reference may be something I want on my bookshelf. Add in the OpenCL Programming Guide<\/a> that I picked up when I was job searching (thought there might be some CT related opportunities and for projective reconstruction, OpenCL seems very interesting) and all sorts of stuff should be possible.<\/p>\n","protected":false},"excerpt":{"rendered":" I find myself back again reading the documentation to OpenGL.
