I've a bizarre questions and I'm not sure if it can be done in Maya. Here it is. When creating default primitives or customized mesh, is it possible to have a preview shown in viewport, which even moved along with mouse until mouse button is clicked? The similar case would be like creating property in games, such as AOE. Although the link below may not be proper, sorry about that, but it shows the basic idea. Example.
I guess the implementation will involve 2D-3D dimension mapping, customized shape API and OpenGL maybe. Has anyone tried to do the similar project before? Any info will be appreciated, Thank you!
