GNNViz Gallery
Below are a collection of images generated in GNNViz during it's ongoing development. All renders are real time and taken in the game environment, where the user has full control of where they look and go in the 3d space modeled.
Demo Video
To get a sense of the movement and scale possible in the GNNViz system, I have >ut up a short demo video.Video 1 - a demo video showing GNNViz.
Video 2 - a short video showing GNNViz with the simulated fire and smoke of a forest fire.
Fire Simulation
One of the potential applications of the GNNViz technology is the visualization of forest fires for various applications, including forest fire training. The following images were taken from a special test version of GNNViz that shows simulated fire and smoke in the 3d environment. |
Foliage Masking
To manage precise foliage placement in GNNViz, we are using a technique we are calling "Foliage Masking". What it does is let us create a mask image that guides where plants should and should not be.Note that the mask does not need to be black and white. The intensity of each pixel in the mask is used to determine the odds of a foliage item being placed on that location, which black meaning no plants, and white meaning normal/full density of plants. Shades of gray handle plant densities in between.

Blue Mountains, Oregon
One of the first areas modeled was in the Oregon Blue Mountains region. Strong terrain variation and mixes of forested and non-forested areas make it an interesting area for visualization.Note that in some of the images the player is carrying a crossbow. This is no longer present in GNNViz, and was a leftover from the game technology being used. Perhaps we should put a Pulaski in the player's hands instead!

Simulated Satellite/DOQ Imagery
The actual foliage coverage and distribution in the GNN dataset does not necessarily match the coverage available from DOQ and Satellite imagery. To prevent visual errors caused by the terrain overlay image not matching the actual dataset, we have explored creating "fake" overview images to be drawn on top of the digital terrain in GNNViz. Here are several examples of derived images, including some which are just the ground image with no trees visible, just the ground texture and the tree shadows. |

Player Model
Each person using the GNNViz tool is represented by a scale character model known as an Avatar. The player avatar moves, walks and behaves somewhat naturally as the user moves about the landscape. Below are images of various player models that have been used in the GNNViz simulation during it's development. |
