The GigaGrid project was created to display huge amounts of date with a minimum loss of performance. To achieve this goal, a new datamodel was created.
The Gigamodel needs to be built from source files to a new split format with several resolutions levels : GigaModel
Once you have built a geometry and properties you can display them.
Rendering allows you to customize a lot of settings to improve performance or maximize full resolution displayed.
Gigagrid rendering also offers a filtering API. You can set several different filters to display what you need, from property to IJK bounding box, with slices I or J or K, and also IJK bounding boxes cavities. All of those filters can also be cumulated, and are rendered in real time.
