Original procedural semitrailer and environment added in scene.js. No texture maps on rims, tires or headlamps. Original spiky outer rubber geometry replaced by smooth 3D lathed tire profiles with rounded shoulders and two shallow circumferential grooves, radius 0.57339m. Original rims replaced with recessed steel rim geometry, ten real ventilation openings and ten nuts per wheel; redundant original front wheel fasteners removed. Tire profiles reduced to 48 radial segments and 12 profile points; four isolated PBR materials for graphite tires, satin rims, diffused headlamps and housings. Removed the separate procedural bars alongside semitrailer wheels.",
    "van": "Mercedes Sprinter from the same CARLA/SimForge library as the supplied SPACE VIEW project. Current optimization retains the original body, door and glass triangle topology without simplification, and preserves source normals and tangents. Only the four wheel meshes were simplified to approximately 35% of their original triangles. Static nodes were flattened and compatible primitives joined by material, from 31 to 6 primitives. WebP textures at maximum 512px; Meshopt compression with 16-bit positions, 12-bit normals and 16-bit UV coordinates; materials adjusted for the fleet scene. Removed 141 redundant triangles from two overlapping internal windshield layers. Retained the original outer windshield surface and normals; all non-glass vertex, normal, tangent, UV and triangle data preserved.",

The primary capabilities view is animated 3D and reuses the hero WebGL renderer, model geometry and textures. Seven physical 3D points serve eight functions, with E-TOLL and SENT/GEO sharing one point."
