Hello,

I'm making C++ plugin which enables to set animation keyframes on a C4D scene camera (or an object) from a data file which contains frame, position, rotation, etc, for example:

Frame, positionX, positionY, positionZ, rotationH, rotationP, rotationB, fovV, fovH
1, 10.0, 20.0, 14.0, 0.0, 0.0, 0.0, 10, 10
2, 11.0, 21.0, 14.0, 0.0, 0.0, 1.0, 9, 10
3, 12.0, 22.0, 14.0, 0.0, 0.0, 2.0, 8, 10
...

I've succeed to read those values but don't know to apply them to a camera object.

Concerning this, I have no idea what class and what methods I have to refer to.

Thank you in advance for you kind reply :)

For the position and rotation you would use those values to set the camera's global matrix. For the FOV settings, get the camera object's base container and set them in that. Don't forget to call yourcameraobj->Message(MSG_UPDATE) when you're done.

Thanks, spedler for your precious time to answer this question.

Then I have one more question.

Is it possible to record the animation keyframes from those value? (like keyframe baking) :)

Thank you for those who read this question.

I'm sure it is possible, but I've never done it so I can't advise much. At a guess you would create a CTrack and add CKeys to it... but I don't know if that's so, or the exact workflow involved.

Someone here will know, for sure.

On my plugins site there's a C++ plugin called "Quick Steps".
I include the source code for all of those plugins:https://sites.google.com/site/scottayersmedia/plugins.

Inside of that plugin code there are a couple of keyframe baking methods that should help you get started with baking keys.

Thank you for your enormous and marvelous answer for that, ScottA.

I've not tried your source code yet, I've already visited your site and downloaded them to analyse and apply to my projects.
