FaceRasterCache

One SceneObjectModel face's own small rendered raster, reused as-is (repositioned to wherever the face's projected position actually is this frame, content unchanged) for a bounded number of frames before a real redraw - see issue #163. Only the pixel CONTENT is ever stale, never the blit position, so there's no geometric transform to get right here - a stale frame just shows this face's texture at last redraw's orientation, correctly placed at this frame's position.

Properties

• bitmap (roBitmap)
• staleFrameCount (integer)
• triangleAtCapture (dynamic) — This face's own 3 canvas-space vertices as of the last real redraw - compared ' against the current frame's vertices to bound how far a face may drift while ' still reusing stale pixel content (see SceneObjectModel.drawFaceWithReuse()).
