Sketching a thin (as in close-to-skia-semantics) scene graph API, focused on
external animation, inval tracking and minimal repaint.
Only a few concrete classes/features so far:
* Rect/Color/Transform/Group
* basic inval tracking
* a trivial animated sample with inval visualization
Pretty much everything (especially naming) is volatile, so treat accordingly.
The interesting bits to review are likely in Node.{h,cpp} for inval and
SampleSGInval.cpp for usage.
Initial class hierarchy:
* Node: invalidation/ancestors tracking
|
-- * RenderNode: onRender(SkCanvas)
| |
| -- * Draw (concrete): rendering a [geometry, paint] tuple
| |
| -- * Group (concrete): grouping multiple RenderNodes
| |
| -- * EffectNode: single-descendant effect wrapper
| |
| -- * Transform (concrete): transform effect
|
-- * PaintNode: onMakePaint()
| |
| -- * Color (concrete): SkColor paint wrapper
|
-- * GeometryNode: onComputeBounds(), onDraw(SkCanvas, SkPaint)
|
-- * Rect (concrete): SkRect wrapper
