terrain_reload/terrain_unload release one map's height field, survey, photograph and patch bounds and generate another at any TERRAIN_HALF; scatter_clear_all (with streams), actor_clear_all, col_reset and mesh_free empty the scene; water_body_add/water_bodies_clear draw several still-water planes with one reflecting; terrain_sea separates the coast's sea level from the carved lake's, and grass keeps off both. Fixes CDLOD patch bounds for TERRAIN_HALF != 4096 and water_init leaking a mesh and program per call. examples/rendering/reload.ludic. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

**ludic.render3d: replace the world at run time** — a game can swap its terrain, scatter, colliders, actors and water for another map's without restarting.
|
|
|
|
- `terrain_reload(dem, emin, emax, base, ox, oz, ortho, half)` releases the current map's height field, survey, photograph and patch bounds and generates another at any `TERRAIN_HALF`; `terrain_unload()` is the release on its own.
|
|
- `scatter_clear_all()` (with `stream_clear_all()`), `actor_clear_all()` and `col_reset()` empty the scene for the next map; `mesh_free()` releases a mesh's GL objects.
|
|
- **Water bodies** — `water_body_add(level, cx, cz, ex, ez, reflect)` and `water_bodies_clear()` draw several still-water planes at their own levels; the first that reflects gets the planar reflection. `water_init` still means one reflecting plane.
|
|
- **Fix:** the terrain's patch quadtree placed patches at a fixed 32 m leaf, so any `TERRAIN_HALF` other than 4096 put patch bounds in the wrong place; leaves now scale with the map.
|
|
- **Fix:** `water_init` built a new mesh and compiled a new program on every call.
|
|
- `terrain_sea(level)` separates the sea's level (the coast, the strand, the shoreline, forest and scree shading) from the carved lake's, so a lake can sit above the sea. Unset, the sea is the lake's level as before.
