2048x1024 JPEG derivative (268258 bytes) from original CC0 panorama; independent authored display derivative, not an original photo of this campus. Static sky, no volumetric clouds.
Ground and vegetation: Poly Haven CC0 assets supplied in ground24 PBR and flower patches. Original 2K textures and source geometry retained. Near-distance visibility and instancing are runtime optimizations, not mesh or texture reduction.

Placement/species/season are illustrative. Source campus building footprints are unchanged. Lotus water height -0.65m is an estimate. No source satellite images or third-party campus photos are distributed.

Current asphalt replacement 20261015-g34-r13-asphalt
Clean Asphalt by Dimitrios Savva, Poly Haven, CC0.
https://polyhaven.com/a/clean_asphalt
https://polyhaven.com/license
Original 2K source diffuse, OpenGL normal, and roughness maps. Road geometry, world UV repeat scale and phase unchanged. The older asphalt_02 credit above is retained as release history; current road PBR uses Clean Asphalt.

Current low-leaf groundcover update 20261015-g33-r18-greenleaf
CC0 celandine_01 and periwinkle_plant from Poly Haven, source mesh shapes and original six embedded2K JPEG image bytes retained. Four authored low-leaf cluster prototypes, with all material primitives instantiated together. No anisotropic source scaling. Mobile LOD keeps up to30clusters within8m of visitor feet; uniform root-fixed fade between6.5and8m. Older grass_medium_01 assets are loaded only as a compatibility fallback.

Continuous2K basecolor is an authored Blender orthographic albedo capture of CC0 celandine leaf/flower meshes over Grass Ground. It contains no baked lighting shadow, no campus photograph. World repeat4m only on source parcel50E; other ground and11CleanAsphalt roads unchanged.

Plant species, density, height, positions and current bloom are illustrative, not surveyed. This is an appearance improvement, not completed photorealistic reconstruction. See GREENLEAF-SOURCE.json for exact embedded-source hashes and authors.

Full-shore update ground38
Existing ground33 and CleanAsphalt materials, source image bytes and UV retained. Seventeen bank overlays reuse original2KGrassGround images with normal scale.35 and roughness1.0; no additional source maps, no recoloring. Bank fallbacks hide only after successful PBR drawing. Original water planar outline, bridges/crossings and independent stadium/court increments retained. Total source-water perimeter approximately2160m, approximately2040m bank and120m protected crossings. Unmeasured bank width/height/guardrails and40tree displacements are display estimates, not as-built survey.

Bermuda near grass, r21: Grass Bermuda 01 by Rico Cilliers, CC0, https://polyhaven.com/a/grass_bermuda_01 . Original authored geometry and official 2048px maps; source alpha hookup corrected to MASK .4. No image resizing. Random bounded placements are illustrative, species/density/season unverified. See BERMUDA-GRASS-SOURCE.json.
50E distant ground uses a gentle distance-dependent color mip sampling bias (0 to 0.8 mip levels) with original full-resolution albedo untouched. Not a claim of complete elimination of device-specific flicker.
Additional rendering adaptation: only fully transparent RGB pixels are nearest-color padded. Alpha and all nonzero-alpha pixels remain bit-exact at2048x2048. Original source and unadapted candidate preserved separately; active file is bermuda-green4-edgepad.glb.

r22 local shrubs: Free Hedges / SmallRound by Yughues (Nobiax), CC0-1.0, https://opengameart.org/content/free-hedges . Original authored512px RGBA and normal pixels preserved;640tri prototype shared by30nodes,19200expandedtri. No original mesh simplification. MASK alphaCutoff.4, double-sided. 24samples describe an estimated16m frontage strip near teaching03;6local activity-centre shrubs replace3prior placeholder spheres. Exact species/number/positions/heights are not surveyed. Source hashes: SHRUB-ASSET-SOURCE.json. No whole-campus tree replacement in this release.

Campus runtime adaptation: combined author LOD0 and LOD2, sharing six 1K mirror-derived images. Original geometry bytes and visible RGBA/alpha pixels preserved. Only fully transparent RGB edge padding, MASK alpha cutoff 0.4, and a common trunk-root transform were applied. Trees are visual substitutes, not verified campus maple species; existing selected tree locations and heights are retained.

2026-10-15 r23b: User-approved all-518 existing-tree visual replacement. Exact existing tree positions, height, yaw and absolute ground38 offsets retained. Same r23 asset, attribution and 1K mirror-derived textures. Authored LOD0/LOD2 instancing with world bounds/frustum culling, stable per-tree hysteresis; no new trees or verified species claim. Existing contact patches remain; new Maple canopy shapes do not cast into the raw campus shadow map.

Grass Medium 02 original curved leaf meshes and 2K textures by Rico Cilliers, Poly Haven, CC0.
Source: https://polyhaven.com/a/grass_medium_02
License: https://polyhaven.com/license
Project adaptation: selected curved green blade components; removed dry/seed parts; lateral width 4x; 18 complete leaves recomposed per clump with radial orientation, uniform variation 0.9–1.1, display scale 0.77. Final three full-clump heights approximately 18.6–20.0 cm. Seasonal material green tint (.62,1,.55,1), MASK .4. Not an untouched original author model or site flora survey.
Project-made LOD: all three tiers retain 18 complete leaf directions and per-leaf bounding extents. Near source meshes unchanged (798/790/784 triangles per clump); middle/far use 4/2 curve segments per leaf (144/72 triangles per clump). The reduced tiers approximate internal curvature and silhouette with fewer triangles; they are lossy project-made LODs, not original author LODs. Root, overall height, radial coverage, original visible 2K texture pixels and alpha are retained.
Runtime image adaptation: only RGB at alpha exactly zero extended from nearest alpha >=.4 texel to reduce dark mipmap fringes. All alpha values and RGBA pixels with alpha >0 remain exact. 2048x2048 dimensions, normal/roughness images and all other GLB buffer views are unchanged; original unmodified source package retained.
Plant distribution, height, density, season and species are illustrative within the existing source 50E ground boundary.
