Tekmap Consulting uses custom software for 3D data visualization. The custom software is built on the Open Source GRASS OGSF visualization library. The software includes all of the features of the GRASS NVIZ program, plus the following features:
- Custom scalebar.
- Custom raster colorbar.
- Text overlay(s).
- 2D location map inset.
- Annotated cutting plane (profile).
Other client specific overlays or features (such as logos, positions, etc) are available upon request.
A number of 3D visualization output products are available. For examples of output products, please visit the Gallery.
|Custom Fly-Through Animations||A fly-through movie created at full resolution along a user defined route or highlighting a user defined feature. Can include above annotations. Available in High Definition (HD) in a variety of formats.|
|3D Still shots||3D views saved to image format with supported overlays. High resolution (poster size) is supported.|
|Multiple surface visualization||3D visualization and animation of multiple surfaces. This is useful for visualizing the difference between repeat surveys. Can also be used to add artificial surfaces such as a water layer to multibeam data.|
|Cutting Plane Visualization||Visualization of 2 or more surfaces with a cutting plane, or profile cutting through the surfaces. Provides excellent cut-away views of data in 3D. Tekmap uses this feature to fly along ice scours while keeping the cutting plane at the center of view. This provides valuable information on the changing morphology on the scour.|
