Is there an arcball implementation for Papervision3D? There are many arcball implementations for Flash/ActionScript but none specifically for Papervision3D. Here's an example of an arcball implementation for flash: http://www.unitzeroone.com/blog/2009/09/08/source-better-flash-10-3d-interaction-arcball/ I have taken to writing my own...
I am trying implement arcball/trackball rotation but I have a problem with the center of rotation. I want the center to be the center of my screen no matter what. Let me explain what I have done so far. I've created a quaterion (rotation axis: vector_start x vector_end, angle: vector_start * vector_end) From that quaternion...
Hi, I have successfully implemented Arcball rotation through quaternions, but am confused at what to do when the direction vector of the camera is parallel to up vector. Currently I am just restricting the rotation along the x-axis (the pitch) when the dot product of the direction vector and the up vector exceeds 0.99. In Maya (or Max, ...
