Detailed Description

Function set for cameras.

Function set for creation, edit, and query of cameras.

Many of the camera settings only affect the resulting rendered image. E.g. the F/Stop, shutter speed, the film related options, etc.

Examples:

animInfoCmd.cpp, D3DResourceManager.cpp, lineManip.cpp, lineManipContainer.cpp, moveNumericTool.cpp, moveTool.cpp, narrowPolyViewerCmd.cpp, scanDagCmd.cpp, scanDagSyntax.cpp, squareScaleManip.cpp, and zoomCameraCmd.cpp.

Member Enumeration Documentation

Specifies how to fit the digital image to the film back.

This describes how the digital image (in pixels) relates to the film back. Since the film back is defined in terms of real numbers with some arbitrary film aspect, and the digital image is defined in integer pixels with an equally arbitrary (and different) resolution, relating the two can get complicated.

Enumerator:
kFillFilmFit  The system calculates both horizontal and vertical fits and then applies the one that makes the digital image larger than the film back.
kHorizontalFilmFit  The digital image is made to fit the film back exactly in the horizontal direction. This then gives each pixel a horizontal size = (film back width) / (horizontal resolution). The pixel height is then = (pixel width) / (pixel aspect ratio). Now that the pixel has a size, resolution gives us a complete image. That image will match the film back exactly in width. It will almost never match in height, either being too tall or too short. By playing with the numbers you can get it pretty close though.
kVerticalFilmFit  The same idea as horizontal fit, only applied vertically. Thus the digital image will match the film back exactly in height, but miss in width.
kOverscanFilmFit  Over-scanning the film gate in the camera view allows us to choreograph action outside of the frustum from within the camera view without having to resort to a dolly or zoom. This feature is also essential for animating image planes.

Computes and returns the intermediate viewing frustum parameters for the camera. The aperture and offset are used by getViewingFrustrum() and getRenderingFrustrum() to compute the extent (left, right, top, bottom) of the frustrum in the following manner:

MStatus MFnCamera::setUsePivotAsLocalSpace ( const bool  how  ) 

Local space tumbling specifies that when the camera is tumbled, the camera will rotate about its local axis, offset by the tumblePivot. The effect is like that of tilting the camera on a tripod. This per-camera setting overrides whatever tumble mode is defined globally in Maya.
