docs(gallery): Utah teapot NURBS hero (public domain)#30
Merged
Conversation
A 3/4 hero of the Utah teapot (Martin Newell, 1975 — public domain) as 32 order-4 NurbsPatchSurface nodes (each bicubic Bezier patch = a NURBS patch with clamped knots + unit weights). Showcases the new NURBS tessellation path with analytic normals: ceramic shading runs smoothly across all 32 patch seams. - examples/cpu_raster/assets/gallery/hero_teapot_nurbs.x3d (self-contained; source/credit in <head> meta; control points from teapotCGA.bpt, public domain) - docs/images/gallery/teapot-nurbs.png (1600x1000, headless cpuraster) - README.md gallery entry

Adds a hero gallery shot showing off the new NURBS tessellation path on a real, recognizable model.
NurbsPatchSurfacenodes (a Bézier patch is a NURBS patch: clamped knots + unit weights). Control points fromteapotCGA.bpt(Holmes3D, public domain); Z-up source rotated to Y-up. Credit/source recorded in the scene's<head>meta.solid="false"(two-sided) sidesteps per-patch winding.examples/cpu_raster/assets/gallery/hero_teapot_nurbs.x3d(self-contained),docs/images/gallery/teapot-nurbs.png(1600×1000, rendered headless), and a README gallery entry.Pure docs/asset addition — no SDK/runtime/CI changes. Depends on the NURBS support merged in #29.
