It appears you have a MBPro 17" (mid-2010) model laptop. The Kernel Panic is referring to a GPU issue which is common with this model. There is a slight chance you may be running some software which may be interfering with the video driver so run EtreCheck and post the report here using the "Additional Text" icon which looks like a piece of paper.
If we don't see any possible software issues in the report, then you most likely have a defective GPU. You may be able to run the gfxCardStatus app to force the laptop to use the Intel GPU instead of the discrete NVidia GPU.
Here is a download for the gfxCardStatus app:

If this doesn't work, then here are some other links to possible workarounds:
