Add a Waterfall helper (graphics/Waterfall.{h,cpp}) built on the custom
Mesh3D shader path that renders a vertical sheet as falling water:
- Downward flow: scrolling fractal noise + elongated vertical streaks
(streakScale) to convey falling velocity.
- White-water foam: turbulent crests in the body plus foam bands at the
top lip (topFoam) and the bottom splash pool (bottomFoam).
- Sky reflection: Fresnel-weighted reflection of the environment cubemap
plus a specular glint from the primary directional light.
- Bottom transparency fade so the sheet melts into the pool.
Push-constant params drive time, flow speed, turbulence, streak
count/scale, top/bottom foam, foam amount, water color, reflection
intensity and sun intensity. Exposed via Graphics::newWaterfall() and
the Squirrel binding (Waterfall class). Also adds Graphics::saveFramePng
to dump the presented frame to a PNG.
Includes a runnable demo (examples/waterfall-demo) and tests: params
round-trip plus a GPU render test proving the waterfall renders, changes
over time (flowing), and differs between calm and foamy configurations.
Add 10 new albedo texture recipes (rock, wood, ripple, cloth, ornament,
spot, zebra, wall, cement, mud) alongside the existing soil/stone/marble/
water/sky_cloud, and introduce full metallic-roughness PBR generation.
A texture is now described by a single TextureRecipeDef (albedo ramp +
displacement field + PBR knobs), so both an albedo ImageData recipe
(tex.*) and a complete PBR set (pbr.*: albedo/normal/roughness/metallic/
height/ao) are derived from the same pixel-aligned height field, with
seamless tiling support.
Expose generatePbrMaterial + pbr recipe listing on the Procgen module and
script bindings. Add tests for expanded recipes, PBR reproducibility,
map ranges, and module/error paths.
Assert registration, per-kind validity (indices/normals/finite positions),
reproducibility, uniform scaling, linear vertex growth with segments, and
seam alignment (unit spans exactly [0, segLength]) for all six recipes.
Add mesh.skyscraper recipe producing a deterministic setback-tiered tower
with a window grid and optional spire. Window quads are raised a thin lip
above each facade so openings read under directional lighting without
coplanar z-fighting.
- Register recipe in MeshRecipeRegistry
- Add topology/height/reproducibility unit tests
- Add render smoke test outputting out/skyscraper.png
- Add interactive example examples/skyscraper-generator/
- Update procgen and module design docs
- Added new test cases for various graphics functionalities, including animation previews, particle effects, and inventory UI.
- Implemented rendering previews for Mixamo animations, Box2D physics, and procedural generation, allowing for real-time visualization during tests.
- Introduced helper functions for drawing graphics elements, improving the clarity and maintainability of test code.
- Enhanced existing tests to utilize the new graphics capabilities, ensuring comprehensive coverage of rendering features.
* docs(procgen): add procedural generation module design
Capture confirmed product direction (runtime map-first, textures
second, pixel/low-poly RPG) plus API sketch, algorithm registry,
configurable outputs, and Phase A checklist.

* docs(procgen): list procgen in module summary table

* feat(procgen): Phase A runtime map generation with DTL
Add eve.Procgen module: semantic Grid2D, algorithm registry, palettes,
and TileLayer/JSON outputs. Built-ins use Dungeon Template Library
(BSP, cellular cave, maze, perlin terrain) plus local drunkard walk.
Includes tests and examples/procgen demo.

* feat(procgen): Phase B runtime pixel texture recipes
Add seamless value-noise texture generation with banded color ramps
for soil/stone/marble/water/sky_cloud, ImageData/Texture/normal outputs,
and script bindings for gfx.newTexture / drawTexturedRect.

* fix(test): qualify eve::image::ImageData in procgen tests
Bare image:: failed to resolve under `using namespace eve::procgen`,
breaking unit_test builds on Linux/Windows/macOS CI.

* fix(procgen): link EVProcgen in tests and fix Apple Clang DTL build
unit_test was missing EVProcgen, causing undefined references on Linux/Windows.
Avoid the DTL umbrella header (broken Voronoi CRTP on Apple Clang) and provide
DrawJagged* compat shims that define the missing drawOperatorArray.
Verified locally: linux-debug build, unit_test link, and all 13 procgen ctests.
