Crusta Virtual Globe

Introduction

Crusta is an immersive virtual globe application.

Crusta enables:

  • representation of global, high-resolution surface data,
  • visualization of these data on a real-time virtual globe, and
  • efficient exploration and annotation using real-time interactive software tools.

Using Crusta one can easily import sub-meter resolution DEM or aerial imagery for any location on the globe. Dynamic manipulation of the visualization using local illumination, real-time scaling of vertical exaggeration, and hardware accelerated textured iso-lines support explorative discovery of key surface features that results in a clear understanding of their three-dimensional embedding. Key features such as fault scarps, landslides, and other historically preserved geologic markers can be directly mapped on the virtual landscape. Real-time mapping and the identification of features using a three-dimensional immersive application greatly improves the confidence and localization of mapped features.

Install

To install Crusta from source, you'll need the following:

  • git
  • cmake 2.8.0+
  • Vrui 2.7 w/ development files
  • GDAL 1.8+ w/ development files
  • GLU w/ development files
  • GLEW

If you want the pretty scenegraph font additions, you'll also need:

  • FTGL
  • Fontconfig

To get going quickly, from the same directory as this file, just do:

cmake . -DCMAKE_INSTALL_PREFIX=/path/for/crusta && make install

If you have any software in a non-standard place, you may need to set the environment variable PKG_CONFIG_PATH. E.g.

PKG_CONFIG_PATH=/path/to/Vrui/pkgconfig cmake . \
  -DCMAKE_INSTALL_PREFIX=/path/for/crusta && make install
