/*!
Shinya Kitaoka 120a6e
The swatch cache delegate is used to temporary store intermediate rendering
Shinya Kitaoka 120a6e
results
Toshihiro Shimizu 890ddd
in cache when an fx is being edited.
Shinya Kitaoka 120a6e
Input fxs of an edited fx are typically requested to produce the same results
Shinya Kitaoka 120a6e
multiple times
Shinya Kitaoka 120a6e
as parameters of their schematic parent change - so, caching these results is a
Shinya Kitaoka 120a6e
remunerative
Toshihiro Shimizu 890ddd
practice as long as the fx is open for edit.
Toshihiro Shimizu 890ddd
Shinya Kitaoka 120a6e
This delegate stores resources on two different levels: one is directly related
Shinya Kitaoka 120a6e
to swatch rendering,
Toshihiro Shimizu 890ddd
while the other is used to cache results on the other rendering contexts.
Toshihiro Shimizu 890ddd
Shinya Kitaoka 120a6e
In the swatch case, we store the above mentioned input results associated with
Shinya Kitaoka 120a6e
the current scene
Shinya Kitaoka 120a6e
scale, releasing them when the scene scale changes; plus, the resource
Shinya Kitaoka 120a6e
associated with the current
Toshihiro Shimizu 890ddd
output is also stored.
Toshihiro Shimizu 890ddd
Shinya Kitaoka 120a6e
In other rendering contexts, the scene scale can be assumed constant - so the
Shinya Kitaoka 120a6e
above distinction
Shinya Kitaoka 120a6e
is unnecessary. All results from the input fxs are stored until the edited fx is
Shinya Kitaoka 120a6e
unset from the swatch.
Toshihiro Shimizu 890ddd
Shinya Kitaoka 120a6e
Please observe that variations in the scene context - such as frame change,
Shinya Kitaoka 120a6e
schematic changes, scene changes
Shinya Kitaoka 120a6e
and so on - actually cause the fx to be re-set for edit in the swatch. Once this
Shinya Kitaoka 120a6e
happens, the previously
Toshihiro Shimizu 890ddd
stored results are conveniently flushed from the cache.
Toshihiro Shimizu 890ddd
*/
Toshihiro Shimizu 890ddd
Shinya Kitaoka 120a6e
/*NOTE: This can be extended in case we realize multiple swatch viewers... It
Shinya Kitaoka 120a6e
should be sufficient to map
Shinya Kitaoka 120a6e
a swatch pointer to its associated cache data - the advantage being that cache
Shinya Kitaoka 120a6e
resources are shared at the
Toshihiro Shimizu 890ddd
same scene zoom.*/
