Imageworks Open Source

Originally developed at Sony Pictures Imageworks, spReticleLoc is a Maya C++ plugin plus MEL code which creates a reticle for a camera. It allows for various camera reference masks to be displayed when looking through the camera, such as filmback, projection gate, and pan and scan attributes.

The value of predefined parameters can be displayed in selectable areas, such as the camera focal length and name, current aspect ratio; frame number, name of the show and shot, Maya scene file name, current user name, etc. Finally, arbitrary textural information can be displayed as well.
