Puppy Ray is a ray tracing filter included in recent versions of Project Dogwaffle. It can run in the graphics processing unit (GPU) of a computer. I have recently acquired a new machine which allows me to better utilize the GPU. Here are my first two experiments running Puppy Ray in the GPU.

The first is a night scene. I have a particular liking for such images perhaps because I have spent so much time living in northern latitudes where winter nights are so long. I also like the bluish cast common to snowy scenes and the contrast between dark and light. And the lack of illumination can make successfully putting together a pleasing image can be a challenge.

Then one when the sun is up, fjords. Water planes processed in Puppy Ray are semi-transparent, allowing for more realistic rendering; i.e. you can see down into the water. The refraction index of the water as well as wave height and frequency can also be fine-tuned.
