[Research] First Image: A model of erosion that allows concave surfaces
This image is our first fully rendered terrain generated using our model of surface erosion that admits concave surfaces. It obviously needs some serious smoothing, but it looks more like a Goblin than our last one. (Algorithm: Matthew Beardall, translation to and mock-up in Bryce by Darius Ouderkirk)
This work was done as part of our BYU CS Capstone class on sandstone erosion modeling.

[Misc.] Mark this quote down
When we do have the first general purpose quantum computer and the computing world is re-invented, this quote by Herb Martin will be famous: "A general purpose quantum computer is a waste of time. You could spend hundreds of billions of dollars on it" and not create a working computer.

[Research] Our First Artifical hoodoo-like shape
Matthew Beardall developed an erosion simulation algorithm which created the following hoodoo-like shape. If you look at it long enough, you can perhaps convince yourself that the algorithm is on the way to generating Goblin Valley Hoodoos (link goes to an image by Eve Andersson).

[Research] Average Sunset on Mt. Timpanogos
This image is the average image created by compositing 43 images of Mt. Timpanogos taken at 99.6% of the lit day over the course of the last 2 months. As such, it represents the average sunset over that time period. The average noon-day picture (taken at 50.0% of the lit day) is bit more murky.
Those 43 images are part of a collection of about 1,200 images that we have recorded of Mt. Timpanogos over the past 6 months. Each image is paired with weather information for the preceding 36 hours. Ultimately, we will use this collection to learn how to recolor images based on weather conditions.
