Hi,
I am working on an animation whereby I wish to recreate a specific natural event, more or less a rock collapse. I have photogrammetric models of a specific site showing before and after a rock collapse, I have identified specific rock components, which I isolated as distinct 3D models, in the "before" and "after" phases, and now I wish to animate a simulation of the collapse showing the specific rock components "falling" from their "before" position to the "after" position. I'm starting to think that keyshot is not the ideal tool for this, but I will just quickly explain what I have tried and where I am getting stuck, maybe I am missing something.
To start, I captured the translation parameters for a rock component by manually moving/rotating it from the "after" position to overlap the same component in the "before" position
First I tried the keyframe method. Unfortunately this does not work like the tutorial (
https://www.youtube.com/watch?v=WKH3qvC5p_g) demonstrates, when I move the model part, the translation and rotation boxes remain at zero, and the "pivot point Center" selection is greyed out. I was also hoping I could simply enter the translation parameters in the "move tool" window which pops up when creating the keyframe, but this does not work at all.
I alternatively tried to use normal animations, a translation animation for X,Y and Z transformation and one rotation animation each for the X, Y and Z rotation angles transformation. The animated model part ends up in a totally different location to the replicated manually moved model part when I do this. I have tried all possible combinations of Axis (local/global) and Pivot Point (center/origin) in the move and in the animation windows, to no avail. I find it strange that using the EXACT SAME transformation parameters one cannot recreate the same transformation. From a few other tests I did, it seems like the issue is how the rotation movement behaves, and I came to this conclusion because I observed that a rotation around an axis (say X) when pivot point is set to Center also changes the
translation parameters of the other 2 axis (e.g. Y and Z), even though the model simply rotates around its own axis, which behaviour I cannot understand at all.
I'm happy to supply more details/screenshots etc if any of the above is unclear.
Thanks
John
