API getFilmFrustum

MStatus MFnCamera:: getFilmFrustum ( double distance, double& hSize, double& vSize, double& hOffset, double& vOffset )


yes you do need pointers because you want to get the values and they have to be stored somewhere. to do this you send the addresses of the variables in which you wan't to store the values.

what errors do you get with the MPointArray? how do you read it?

There are no pointers in python except for c_types. I tried those but little difference.

For the MPointArray
fnCamera.getFilmFrustum(f1, cam_clipPlanes)
cam_clipPlanPoint= OpenMaya.MPoint()
cam_clipPlanPoint=cam_clipPlanes[0] # this causes an error

Then i looked into MFnPointArrayData and MDataHandle but it's a bit of overdone for extracing 4 points from an array, or is this the way?

I found in c++ that getViewingFrustum seems to be in worldspace and is closer to what i want.
But it is also unhappy with the datype of the arguments:
# TypeError: in method 'MFnCamera_getViewingFrustum', argument 3 of type 'double &' //
