Cell graphs, views and surface mazes

Flat and surface graphs

import {buildSolidMaze,solidSolutionOf,checkSolidAnswer} from "@johnmorrisdotca/meikyuu/3d";
const maze = buildSolidMaze({kind:"cube",n:2,algorithm:"backtracker",seed:42});
console.log(maze.grid.cells,checkSolidAnswer(maze,solidSolutionOf(maze)));

The same carving logic reads adjacency lists, whether cells live on a flat mask or a solid. Surface coordinates have three components and cells can cross face boundaries. A rotation quaternion or projection changes where cells appear, not their links. Logical paths and recipe codes survive view changes.

Pointer and scale units

Flat view functions use viewport pixels and logical board bounds. Surface frame functions project vertices/centres, track facing/visibility and pick the cell under a pointer. Do not use a screen point as a graph cell or a 2D point as a 3D vector. Quaternion interpolation uses a normalized rotation and a share from 0 to 1; turn angles use radians. Tall collection size is an index, not width; a surface subdivision n differs from a named level size.

Use /3d/play for the native rotation/zoom player and cleanup. The surface usage, geometry design and drawing guide preserve the detailed native conventions.
