One of the important goals of undergraduate geology courses is to help students learn how to visualize geologic structures in three dimensions. Students are asked to visualize structural geometries from geologic maps, cross sections, block diagrams, and actual landscapes. Toward this goal, we developed GeoBlocks 3D, which contains interactive QuickTime Virtual Reality movies illustrating the three-dimensional nature of geologic structures within blocks. Students can rotate the blocks, make them partially transparent to view their internal structure, cut through or erode them, displace faults, and more. The movies are designed so that students must be actively engaged, interacting with the blocks by clicking and dragging, either up or down or left and right. The GeoBlocks 3D materials have been used in introductory geology courses and undergraduate structural geology, both with great success.
