All the objects are already loaded into directX/openGL, only a few tweaks to tell it to render some extra pieces would be necessary

Most games/3d apps do view frustum culling of geometry before sending the geometry to OpenGL/DirectX. This means that not all the geometry required to render a 360 view is available without tweaking the application itself; which I may add is non-trivial.

Submission + - Carmack speaks on ray tracing, future id engines (pcper.com)

Vigile writes: As a matter of principle, when legendary game programmer John Carmack speaks, the entire industry listens. In a recent interview he comments on a multitude of topics starting with information about Intel, their ray tracing research and upcoming Larrabee GPU. Carmack seems to think that Intel's direction using traditional ray tracing methods is not going to work and instead theorizes that using ray casting to traverse a new data structure he is developing is the best course of action. The "sparse voxel octree" that Carmack discusses would allow for "unique geometry down to the equivalent of the texel across everything." He goes on to discuss other topics like the hardware necessary to efficiently process his new data structure, translation to consoles, multi-GPU PC gaming and even the world of hardware physics.
