This applies an OpenColorIO display, view and look transform on a color in the scene_linear colorspace. In general, OpenColorIO configurations do not contain a colorspace for every view + display, especially if they are modern configs using the display colorspace and shared view mechanisms. Nor do they include looks. So the Convert Colorspace node is not sufficient. Additionally, we would like to avoid making the colorspace list too long in the default config, as we are adding many new views and transforms. Exposure, gamma curves and white point functionality are not included in this node, as there are native ways of doing that in the compositor. These settings are marked non-editable in the Python API.

* Static Cache Manager
|
|
*
|
|
* A static cache manager is a collection of cached resources that can be retrieved when needed and
|
|
* created if not already available. In particular, each cached resource type has its own instance
|
|
* of a container derived from the CachedResourceContainer type in the class. All instances of that
|
|
* cached resource type are stored and tracked in the container. See the CachedResource and
|
|
* CachedResourceContainer classes for more information.
|
|
*
|
|
* The manager deletes the cached resources that are no longer needed. A cached resource is said to
|
|
* be not needed when it was not used in the previous evaluation. This is done through the
|
|
* following mechanism:
|
|
*
|
|
* - Before every evaluation, do the following:
|
|
* 1. All resources whose CachedResource::needed flag is false are deleted.
|
|
* 2. The CachedResource::needed flag of all remaining resources is set to false.
|
|
* - During evaluation, when retrieving any cached resource, set its CachedResource::needed flag to
|
|
* true.
|
|
*
|
|
* In effect, any resource that was used in the previous evaluation but was not used in the current
|
|
* evaluation will be deleted before the next evaluation. This mechanism is implemented in the
|
|
* reset() method of the class, which should be called before every evaluation. The reset for the
|
|
* next evaluation can be skipped by calling the skip_next_reset() method, see its description for
|
|
* more information. */
