Detailed Description

The film class handles accumulation of samples with any distorted camera_type using a pixel filter. Inputs needs to be jittered so that the filter converges to the right result.

In viewport, we switch between 2 accumulation mode depending on the scene state.

• For static scene, we use a classic weighted accumulation.
• For dynamic scene (if an update is detected), we use a more temporally stable accumulation following the Temporal Anti-Aliasing method (a.k.a. Temporal Super-Sampling). This does history reprojection and rectification to avoid most of the flickering.

The Film module uses the following terms to refer to different spaces/extents:

• Display: The full output extent (matches the full viewport or the final image resolution).
• Film: The same extent as display, or a subset of it when a Render Region is used.
• Render: The extent used internally by the engine for rendering the main views. Equals to the full display extent + overscan (even when a Render Region is used) and its resolution can be scaled.
