| Format | Sampling logic in shader | |------------------|-------------------------------------------------| | Side‑by‑side | leftCoord.x = vTexCoord.x / 2 | | Over‑under | leftCoord.y = vTexCoord.y / 2 | | Full‑frame left/right | Use separate textures if available |

The renderer’s SurfaceTexture feeds frames to the shader. Add a setting in UI:

fun getSurfaceTexture(): SurfaceTexture = surfaceTexture
