Camera path along a 3D building model?

General TouchDesigner Discussion

Hi all,

I have a 3D building model and I want to create a camera navigation along its corridors, stairs etc., like a virtual tour. Tried to do it using various camera COMP positions and then using Camera Blend to sequence the path from one position to the next. However this method is not really working well, as it the camera orientations are all over the place. Any idea why I could approach this?

Hi,

You could build a bezier path in your 3d modeling app, export it to TD and then use the SOPtoCHOP operator to extract the path and sample it for coordinates to animate your camera along.

Here’s a slightly more complex version that adds a simple camera rig and offset target to make the camera view vector follow the path.

Thanks a lot @flowb! This looks like a pretty neat way to deal with orientation in a complex path, I 'll definitely use it.

Hi @Tasos_A . Happy to help. I just updated the second example with some fun visuals and smoother interpolation. Have fun :slight_smile:
