The heightmap data pipeline works correctly (verified: + CPU terrain heights track modified heightmap). But Ogre terrain's + `dirty()` + `update(true)` updates CPU memory only; the GPU + vertex buffers are NOT refreshed.

Paging system's definer + (`CustomTerrainDefiner`) overwrites import data unless paging is + disabled; even with paging off, GPU doesn't refresh. -**Tool selector**: Combo box — Raise, Lower, Smooth, Flatten, Splat Paint. -Switching the tool immediately changes behavior; no separate "activate" step. + **Promising direction**: The legacy `updateHeightmap()` in + `src/gamedata/EditorGUIModule.cpp` uses `mTerrainPagedWorldSection-> + unloadPage()` + `mTerrainGroup->update(false)` — this works through + the paging system properly. For editor mode, the camera needs to + be attached to `PageManager` so auto-reload works. It is very slow. -**Painting**: In sculpt mode, holding left mouse on the terrain continuously -applies the current tool at the brush position (determined by raycast against -terrain via `TerrainSystem::raycastTerrain()`). Releasing the mouse stops -painting. The brush follows the cursor — drag to paint a stroke. A -translucent circle decal on the terrain surface shows brush position and -radius. - -**Camera interaction while sculpting**: -- Right mouse always controls camera (orbit/pan), even in sculpt mode. -- Middle mouse or Ctrl+Left also moves camera in sculpt mode, so the user - can reposition without toggling the mode off. - -**Brush tools**: -- **Raise**: adds height (strength × radius curve) at brush center. -- **Lower**: subtracts height. -- **Smooth**: averages heights within brush radius. -- **Flatten**: pulls heights toward the height under brush center (plateau). -- **Splat Paint**: paints selected layer's blend weight via - `TerrainLayerBlendMap::setBlendValue()` + `dirtyRect()` + `update()`. - Layer selector appears when this tool is active. - -**Brush application and dirty page marking**: -- During a stroke, `HeightmapData::setHeightAt()` is called for each affected - sample within the brush radius, weighted by the radius curve. -- At mouse release (end of stroke), determine which terrain pages overlap the - modified area and mark them dirty. -- `CustomTerrainDefiner` re-samples `HeightmapData::getHeightAtWorld()` on the - next `define()` call for dirty pages. -- If a modified page already has a physics collider, queue its removal and - recreation with updated heights. + **Alternative**: Render terrain heights via a custom + `Ogre::ManualObject` mesh that mirrors the heightmap, bypassing + Ogre terrain rendering entirely for real-time editing preview. + It is more work but much better. Make sure the mesh is generated in the same way + as Ogre terrain's mesh in zigzag pattern. Then only vertices Y coordinates can be updated. + The mesh should show all loaded chunks pages and show height directly allowing to see the change quickly. + The flow should be like: + - Sclupt Mode checkbox enabled + - Page loading should be disabled by removing camera from PageManager or other way. + - Already loaded pages should be remembered and unloaded so no terrain chunks rendered. + - For all remembered pages ManualObject should be generated which directly represents heightmap + - It should be showing height replica of original terrain chunk, but with single color but shaded look + to understand its geometry easier. + - As geometry modified via brush, the manual object for appropriate chunk should be rebuilt with changed vertices. + It can also easily be just plain vertex buffer update with only changing vertex part as index part is the same. + This can be optimized for partial updates and read/write buffers, so that updates are fast. + - As Sculpt mode checkbox gets updated, the height updates get flushed, then manual objects get deleted, pages loaded back and paging enabled as before sculpt mode. -**Heightmap file I/O and AuxMap controls**: -- "Save Heightmap" / "Load Heightmap" buttons in the TerrainEditor panel. -- AuxMap management: create, rename, delete, select active map for editing. - AuxMap editing uses the same brush tools but writes to the selected aux map - instead of the base heightmap. -- "Clear All Fixups" button — deletes all fixup chunks and marks affected - pages dirty for rebuild. +5. **Brush decal not working** — The translucent circle indicator + (`Ogre::ManualObject` with alpha blending) renders as opaque white. + RTSS material override prevents `setSceneBlending()` from taking + effect. **Fix**: Use per-vertex colours with alpha + material + with `scene_blend alpha_blend` explicitly set on the pass + (bypassing RTSS by setting the scheme or using raw materials). -**Definition of done**: user can sculpt terrain with visual brush feedback; -save scene, reload, terrain restored with edited heightmap and layer paint; -visual and collision update after sculpting; camera can be snapped above -terrain on demand. +6. **Default brush radius too small** — Default 5.0 on a 2000-unit + page covers ~1 vertex. Should default to 50-150 for visible + effect. Slider range currently 0.5–50; should be 5–500. ### Milestone 4 — Procedural roads - Node/edge editing UI (add, remove, split, join, select, move). diff --git a/src/features/editScene/systems/TerrainCommands.hpp b/src/features/editScene/systems/TerrainCommands.hpp new file mode 100644 index 0000000..24e7d1c --- /dev/null +++ b/src/features/editScene/systems/TerrainCommands.hpp @@ -0,0 +1,189 @@ +#ifndef EDITSCENE_TERRAIN_COMMANDS_HPP +#define EDITSCENE_TERRAIN_COMMANDS_HPP +#pragma once + +#include +#include +#include +#include + +/** + * @file TerrainCommands.hpp + * @brief Command-pattern terrain editing API. + * + * Terrain editing operations (raise, lower, smooth, flatten, splat paint) + * are encapsulated as command objects that can be queued, executed + * synchronously, and scripted from Lua. + * + * Usage (C++): + * @code + * TerrainSystem *ts = TerrainSystem::getInstance(); + * TerrainCommandQueue &q = ts->getCommandQueue(); + * q.push(TerrainCommand::raise(worldPos, radius, strength)); + * q.push(TerrainCommand::splat(worldPos, radius, strength, layerIdx, weight)); + * q.executeAll(); // blocks until all done, results in q.results() + * // On next update(), rebuildDirtyPages() picks up the changes. + * @endcode + * + * Usage (Lua): + * @code + * local q = terrain.create_command_queue() + * terrain.queue_raise(q, x, y, z, radius, strength) + * terrain.queue_splat(q, x, y, z, radius, strength, layer, weight) + * local results = terrain.execute_queue(q) + * @endcode + */ + +/* ------------------------------------------------------------------ */ +/* TerrainCommand — one brush operation */ +/* ------------------------------------------------------------------ */ + +enum class TerrainCommandType { + Raise, + Lower, + Smooth, + Flatten, + SplatPaint +}; + +struct TerrainCommand { + TerrainCommandType type = TerrainCommandType::Raise; + + /* Brush center in world-space coordinates. */ + Ogre::Vector3 worldPos = Ogre::Vector3::ZERO; + + /* Brush radius in world units. */ + float radius = 5.0f; + + /* Brush strength 0..1 (opacity of the effect). */ + float strength = 0.5f; + + /* Layer index for SplatPaint (0 = first blend layer). */ + int layerIndex = 0; + + /* Blend weight for SplatPaint (0..1, 0 = erase, 1 = full paint). */ + float splatWeight = 1.0f; + + /* --- Results (populated by executeAll) --- */ + bool executed = false; + bool success = false; + int pagesAffected = 0; + std::string errorMsg; + + /* Factory helpers */ + static TerrainCommand raise(const Ogre::Vector3 &pos, float radius, + float strength) + { + TerrainCommand c; + c.type = TerrainCommandType::Raise; + c.worldPos = pos; + c.radius = radius; + c.strength = strength; + return c; + } + + static TerrainCommand lower(const Ogre::Vector3 &pos, float radius, + float strength) + { + TerrainCommand c; + c.type = TerrainCommandType::Lower; + c.worldPos = pos; + c.radius = radius; + c.strength = strength; + return c; + } + + static TerrainCommand smooth(const Ogre::Vector3 &pos, float radius, + float strength) + { + TerrainCommand c; + c.type = TerrainCommandType::Smooth; + c.worldPos = pos; + c.radius = radius; + c.strength = strength; + return c; + } + + static TerrainCommand flatten(const Ogre::Vector3 &pos, float radius, + float strength) + { + TerrainCommand c; + c.type = TerrainCommandType::Flatten; + c.worldPos = pos; + c.radius = radius; + c.strength = strength; + return c; + } + + static TerrainCommand splat(const Ogre::Vector3 &pos, float radius, + float strength, int layerIndex, + float splatWeight) + { + TerrainCommand c; + c.type = TerrainCommandType::SplatPaint; + c.worldPos = pos; + c.radius = radius; + c.strength = strength; + c.layerIndex = layerIndex; + c.splatWeight = splatWeight; + return c; + } +}; + +/* ------------------------------------------------------------------ */ +/* TerrainCommandQueue — FIFO queue with synchronous execution */ +/* ------------------------------------------------------------------ */ + +class TerrainSystem; + +class TerrainCommandQueue { +public: + TerrainCommandQueue() = default; + + /** Push a command to the back of the queue. */ + void push(const TerrainCommand &cmd) { m_queue.push_back(cmd); } + void push(TerrainCommand &&cmd) + { + m_queue.push_back(std::move(cmd)); + } + + /** + * Execute all queued commands synchronously. + * + * Each command is applied to the heightmap data immediately.
