VRSpatial Program

June 22, 2010
VRSpatial Program VRSpatial program is being used to design a spatial 4C linkage in the C6 virtual reality facility at Iowa State University. Motion synthesis of mechanisms relies on the designer's ability to specify desired locations of an object, select a solution, and visualize relative motion of the resultant mechanism. While synthesizing spatial mechanisms, designers specify the problem in 3 Dimensions and select solutions from a 3-D solution set. Virtual Reality technology provides a truly 3-D environment in which real size objects are drawn, and users interact with the objects using natural 3D human movement. This image shows users selecting a solution from a generated set of the fixed and moving congruence's. The congruences are sets of lines that define the fixed and moving axes of the joints of a spatial 4C mechanism capable of guiding a body through the four specified design locations in space. They are represented in the design environment by finite-sized red and yellow planes respectively, with every plane representing an infinitely large set of congruence lines parallel to each other. This research was supported by a grant from the National Science Foundation's Division of Design and Manufacturing Innovation, grant DMI 98-72604. (Date of Image: May 29, 2002)
