Play an actual .riv, turn its live image into oil paint, vector splats, phosphor traces or an orbitable time volume, then export the entire player. The source stays a Rive document throughout.

RGB error is measured at 96 × 64 against the Gaussian renderer. Geometry and colours are optimized with accepted loss-decreasing steps. A complete step may exceed the requested time budget; the measured batch time is shown. Pause the source to measure convergence; animation reuses the previous fit. Rive uses a palette and eight ellipse layers per Gaussian, so its approximation has a separate display error.

KEEP THE WHOLE WORKFLOW
Export a working browser player.
The HTML carries the original .riv, official runtime, WASM, pipeline settings and captured history. Open it directly in a browser. The layered-splat snapshot exports actual ordinary Rive ellipses.
RIVE → TEXTURE → RIVE
The final marks can be Rive too.
Compare fitted Gaussian shader splats with eight concentric translucent ellipses per mark, drawn by the official Rive renderer. A bounded gradient optimizer adjusts position, covariance and RGB to reduce reconstruction loss at 96 × 64. The displayed residual reports that objective. Both routes use the same optimized marks, including dark details. A fixed ordinary Rive shape pool updates every display frame. It uses 24 or fewer source-derived colors and a bounded mark budget; the static snapshot export keeps full sampled color. This is a warm-started 2D image fit, not a trained 3D Gaussian scene. A changing source changes the objective; freeze it to see convergence. This illustrates an approximation with a real vector cost, not an arbitrary Gaussian feather feature in vanilla Rive.
IMAGE HISTORY AS A VOLUME
Time becomes the third axis.
Studio mode stores 128 actual 512 × 512 frames and raymarches up to 192 samples per ray. RGB, motion density and iso-sheets share that history. STM uses luminance as height; it is an image relief, not recovered scene depth. Beam traces ordered extracted contours into a decaying phosphor buffer.
RUNTIME OWNERSHIP
A working hybrid, with clear boundaries.
The imported artboard, timelines and state machines use official Rive. Oil, Gaussian splats, beam and space-time use custom WebGL2. The browser extracts image contours; the desktop beam also has original path access. Hybrid HTML is self-contained, but is not a native .rivx or GPU Canvas .riv export. GPU Canvas export status →
Earlier exported players. Open the real artifact.
These are saved self-contained HTML players from the earlier workshop revision. Their splat examples use the earlier adaptive-patch approximation; use the live controls above and export again for optimized fitting. Each carries its Rive input, runtime, effect code and saved settings. They resume with Play; no local desktop backend is needed.
The animated effect is in the hybrid HTML. “Export fitted geometry .riv” saves one static vector approximation; it does not package a shader, phosphor simulation or history volume into vanilla Rive.
