| description | We describe a novel method implemented in the GPlates plate tectonic
reconstruction software to interactively reconstruct arbitrarily
high-resolution raster data to past geological times using a rotation model.
The approach is based on the projection of geo-referenced raster data into a
cube map followed by a reverse projection onto rotated tectonic plates on
the surface of the globe. This decouples the rendering of a geo-referenced
raster from its reconstruction, providing a number of benefits including a
simple implementation and the ability to combine rasters with different
geo-referencing or inbuilt raster projections. The cube map projection is
accelerated by graphics hardware in a wide variety of computer systems
manufactured over the last decade. Furthermore, by integrating a
multi-resolution tile partitioning into the cube map we can provide
on-demand tile streaming, level-of-detail rendering and hierarchical
visibility culling, enabling researchers to visually explore essentially
unlimited resolution geophysical raster data attached to tectonic plates and
reconstructed through geological time. This capability forms the basis for
interactively building and improving plate reconstructions in an iterative
fashion, particularly for tectonically complex regions. |
