Whereas the GeoWall was designed to address the community's need for 3D stereoscopic visualization, EVL developed GeoWall-2 to evaluate their need for screen resolution. GeoWall-2 is a tiled display built from an array of 5x3 LCD tiles and driven by a cluster of 9, 32-bit PCs (each PC driving 2 displays, and 1 extra PC as the master controller).
To give individual geoscience researchers a GeoWall-2 system that can fit inside a small office, EVL has developed the Personal GeoWall-2 (PG2). PG2 is essentially a GeoWall-1 that has been enhanced with an extra multi-headed graphics card so that in addition to driving a passive stereo display, it can also simultaneously drive a 2x2 tiled LCD display.
CoreWall's high-resolution tiled LCD display gives geoscientists a large-scale perspective, helpful in processing and comparing high-resolution digital line-scan images of cores measuring up to hundreds of feet long.
