First, thanks for all the help so far, replies have been very quick.
I am trying to do a path animation through a building. I am able to constrain the camera to the path just fine, but I am finding that directing where the camera should look as it travels along that path is EXTREMELY difficult… my guess is that I don’t understand the proper technique. I’ve been trying to follow the technique specified here: http://bongo.rhino3d.com/page/multiple-constraints-and-weighting
The reason this tutorial isn’t working for me is that I have a very dynamic and precise idea of where the camera should be looking at each point along the path. Every time I add a constrain to target point, it weighs in and changes the direction of all previous points, unless I go to each one and enter the weight as zero. It is prohibitively cumbersome to re-assign the weight to all object targets for each target that I add (There are 30-40 targets for the whole anmiation). This numeric control of where the camera is looking is impossible to get right.
The second technique I have tried is constraining the camera to travel along a path, and then adding keyframes with the ‘walkabout’ command on in Rhino. The problem I get here is that the view drifts out of being orthagonal. I tried putting ‘show camera’ in rhino, so that I might be able to drag the camera points around and just point it where I want it to look, but the camera points aren’t selectable, and Bongo doesn’t always save the camera position correctly— it feels like a bug.
I feel like there must be a simple way to do this. All I want to do is draw a curve in rhino that the camera should travel along, and then incrementally point the camera at different targets along that curve with smooth transitions in between. Any help would be much appreciated.
