static bool	IsContinuous (RadientFrameID PreviousFrameID, RadientFrameID CurrentFrameID) noexcept

Detailed Description

Per-view temporal state used to generate camera and object motion vectors. Global render frame IDs invalidate all history when the view skips a frame. Drawable generations prevent recycled IDs from inheriting old transforms, while view frame numbers invalidate history after a drawable was not rendered by an otherwise continuously rendered view.

Member Function Documentation

BeginFrame()

void Diligent::RadientTesseraFrameHistory::BeginFrame ( RadientFrameID RenderFrameID )

noexcept

Starts history tracking for a view rendered during RenderFrameID. Temporal history is reset unless the view was last rendered during the immediately preceding global render frame.

IsContinuous()

bool Diligent::RadientTesseraFrameHistory::IsContinuous ( RadientFrameID PreviousFrameID, RadientFrameID CurrentFrameID )

staticnoexcept

Returns whether CurrentFrameID immediately follows PreviousFrameID, including wraparound to 1. Invalid frame IDs never form a valid pair.
