summary This article presumes the primacy of spatial cognition in evaluating architectural designs and begins by describing key concepts involved in the perception of spatial form, focussing on parallax and stereoscopy. The ultimate emphasis is directed at presenting techniques which employ computers with modest hardware specifications and a basic three-dimensional modeling software application to produce sophisticated imaging tools. It is argued that these techniques are comparable to high end computer graphic products in their potentials for carrying information and in some ways are superior in their speed of generation and economies of dissemination. A camera analogy is considered in relation to controlling image variables. The ability to imply a temporal dimension is explored. An abbreviated summary of pertinent binocular techniques for viewing stereograms precedes a rationalization and initiation for using the cross-convergence technique. Ways to generate and view stereograms and other multiscopic views using 3-D computer models are described. Illustrations from sample projects show various levels of stereogram rendering including the theoretically 4-D wireframe stereogram. The translated perspective array autostereogram is presented as an economical and easily reproducible alternative to holography as well as being a substitute for stop action animation.
