Hydra schema for a camera that pulls the params (see above) during Sync.
Backends that use additional camera parameters can inherit from HdCamera and pull on them.
| HD_API GfMatrix4d ComputeProjectionMatrix | ( | ) | const |
Convenience API for rasterizers.
Computes the projection matrix for a camera from its physical properties.

Get the raw exposure exponent value.
This the same as the value stored in the exposure attribute on the underlying camera. Note that in most cases, you will want to use GetLinearExposureScale() instead of this method, as it is the computed end result of all related exposure attributes. GetExposure() is retained as-is for backward compatibility.

Returns the minimal set of dirty bits to place in the change tracker for use in the first sync of this prim.
Typically this would be all dirty bits.
Implements HdSprim.

Get the computed linear exposure scale from the underlying camera.
Scaling the image brightness by this value will cause the various exposure controls on UsdGeomCamera to behave like those of a real camera to control the exposure of the image.
