1. A system comprising: a programmable processor-based subsystem configured to generate simulation data corresponding to a virtual weldment generated in real time in virtual reality space, wherein a weld bead portion of the virtual weldment results from a simulated weld puddle having real-time molten metal fluidity and heat dissipation characteristics providing a real-time fluidity-to-solidification transition of the simulated weld puddle as the simulated weld puddle is moved to form the weld bead portion of the virtual weldment; a three-dimensional (3D) conversion unit operatively connected to the programmable processor-based subsystem and configured to convert at least a portion of the simulation data, representative of at least a portion of the virtual weldment, to 3D data in a stereoscopic 3D transmission format in real time; and a 3D display-facilitating device operatively connected to the 3D conversion unit and configured to receive the 3D data, in the stereoscopic 3D transmission format, from the 3D conversion unit and facilitate displaying of a stereoscopic representation of the 3D data in a stereoscopic display format in real time.
