lvj / largesurfacevisualizer

The LargeSurfaceVisualizer is a javascript framework to visualize arbitrary large raster or image data in 2D and 3D. Using an iipimage server and osg.js, the LargeSurfaceVisualizer can render very high-resolution images such as scanned surfaces, Terrains/DEMs, or other 2.5D datasets in your browser.

Building

Please check out the repository including its submodules. The project requires a custom osgjs version, that is checked out automatically.

Building osgjs

Go to ./sources/external and install the required packages

cd ./sources/external npm install

Once all dependencies are install you can use grunt to build osgjs

grunt build-release

Upon succesfull build two files are create

./sources/external/OSG.js ./sources/external/OSG.min.js

Building the LargeSurfaceVisualizer

Go to the root directory of your project and install the required packages

npm install

Once all dependencies are install you can use grunt to build and test the LargeSurfaceVisualizer

grunt build-release

Builds the project to

./builds/dist/cruse.js ./builds/dist/cruse.min.js

Examples

In order to test the LargeSurfaceVisualizer, different examples are provided. To run the examples and tests call

grunt serve

This will open a local server on

http://localhost:9000/

The source code of the examples can be found in the examples folder. For these examples all iipserver requests are forwared to one of Cruse's iip-servers.
