Orkuncakilkaya a4a3d75cd9 feat(render3d): replace the world at run time, water bodies, terrain_sea 
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.

Raw Blame History

bump: minor type: feat 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.
