Viewport resolution in pixels
OptionalisOrtho: boolean
Whether camera is orthographic (default false)
OptionalnearCull: number
Near-fade start distance in world units (consumed by all four geometry materials via the shared perspectiveNearFade)
OptionalpixelRatio: number
Physical render-target pixels per CSS pixel; screen-space appearance constants scale with it above 1×
Update camera-dependent uniforms (viewport, projection kind, near cull).
Push again after a resize, a projection-kind flip, a near-cull change or a pixel-ratio change. An FOV or ortho-zoom change needs no push.
