temporalTorture

The temporal reference: the content a temporal resolve gets wrong, under temporal antialiasing.

Contents

• ReferenceCamera: the station every reading is taken from, at {0, 1.5, 9} looking down -Z; CutCamera is a second station ({6, 3, 6}, turned 40 degrees toward the scene, priority -1). A camera cut is the viewport going from one to the other (camera.setEditorOverride(id)), the frame a resolve has to drop its history on.
• TemporalAntiAliasing: the scene's temporal antialiasing at its defaults.
• SiemensStar: 36 spokes of 0.9 on 0.02 (postReference_siemensStar, unlit); toward its centre the spokes are narrower than a pixel.
• Wire0..Wire4: horizontal wires 0.016 units thick, thinner than a pixel at this distance (postReference_white, unlit).
• FencePost0..FencePost16 and FenceRail0 / FenceRail1: a fence of thin white posts at a regular pitch, the pattern a jittered resolve shimmers on.
• Fan with FanBlade0..FanBlade3: four white blades turning at 8 radians per second (Mover.spin).
• FastObject: a lit grey cube carried round a 2-unit circle at 3 radians per second (Mover) in front of CheckerBackdrop, a 64-cell checker (postReference_checker).
• Everything stands on the scene's dark clear colour, so thin geometry is read against a flat field.
• Sun and Ambient light the lit parts.

The movers turn while the engine plays (engine.mode = "play"); in edit mode the scene holds still.

The scene's player intent is none. Put the viewport on ReferenceCamera and read consecutive frames with renderer.presentedFrames({ frames = n }); postMetrics.temporalVariance reads how much each pixel changes across them.
