Camera Scripting

[invaderzimm77]

Does any one know how to create a camera that has an aiming node using only code?,
also how to set the min and max rotation of the camera's axis?

do you want create your own camera in maya ??? or do you want the command for create a maya camera through script ??

i want to make a camera rig for a 3D Projector and i want to write it out as a script so that it can be made into a button on a shelf, in the end what i need is three cameras with the same focal point(aiming node(I've made an expression that tells the node to copy the node i want it to).

then just create an expression that calculates the vector between the camera and the "aim target" and apply this vector to the camera

'i'm not sure what you mean by "aim target", but that still doesn't explain how to create a camera with an aiming node.

Turn echo all on and make one camera with aim node and see what maya does in the script editor. Quite simply echoes:

camera ....;objectMoveCommand;cameraMakeNode 2 "";

so you tip that the aim is made by cameraMakeNode 2 ""; and because it has no name thet its working on active selection. So if you for example wanted aim for a existing camera persp youd tip calling cameraMakeNode 2 "perp"; would work and it does. Incidentally if you want aim up you set 3 instead of 2.

This may or may not work in batch mode tough since its not a factory scipt in wich case you go and take a looksee at the file that whatIs cameraMakeNode; points at.

amazing joojaa! didnt think its that simple,

and just to clarify what i said, the aim target is any object you choose, u can make it a locator or anything, and then do the math according to its position.
