Cudaray added glossy material and nexus trial

Glossy is actually a multi-layer material, but Cuda does not support some abstract functions and is difficult to construct.

The dynamic shade tree is simplified to diffuse + anisotropic.

Mongoda did a lot of work on cuda, and now the debugging tool nexus based on Visual Studio 2008 is in beta1,

I applied for a number and tried it.

1. Currently, only two machines are supported and connected over TCP. One GPU is required to support Cuda. I only have one machine and have never tried it.

2. One machine is running with two GPUs, which is not publicly supported by the official website. However, there are related documents. I found out the old 7300 card.

I tried it and it worked normally. For some examples provided by nexus beta, there is no problem with debugging. You can directly observe the GPU running.

Status, greatly facilitating development. But then I try to debug my ownProgramEven the breakpoint settings are incorrect.

The breakpoint is invalid. Sometimes it is interrupted, but the corresponding Source Code cannot be found.

In short, the conclusion can only deal with simple programs, but there are still too many bugs for the bigger ones, which cannot be used.
