Book Cover

Parametric 3D book — a single tilted hardcover, a stacked group, or a horizontal shelf, all from one BookCover atom. Pure CSS 3D (perspective + rotateX/Y/Z, no library): typographic OR image cover, page-block fore-edge, spine, solid + wireframe variants. Optional grab-to-orbit drag (mouse/touch) with an onRotateChange callback. Wireframe edges/faces and the scene background default to shadcn theme tokens, so it adapts to light/dark. Geometry and colors are all props, so the demo doubles as a cover generator with Copy JSON + Export JPG.
