GlyphCamera

<GlyphCamera> (alias for <GlyphOrthographicCamera>) is the outermost element in a glyphcss tree. Wrap <GlyphScene> inside it. The renderer and the hit layer both read from the same camera state — mutating rotY updates both simultaneously.

Props — orthographic (GlyphCamera / GlyphOrthographicCamera)

Prop	Type	Default	Description
rotX	number (degrees)	65	Tilt around X axis
rotY	number (degrees)	45	Spin around Y axis
zoom	number	0.65	CSS pixels per world unit

Props — perspective (GlyphPerspectiveCamera)

Prop	Type	Default	Description
rotX	number (degrees)	65	Tilt around X axis
rotY	number (degrees)	45	Spin around Y axis
zoom	number	0.65	CSS pixels per world unit
distance	number	0	Camera pull-back. CSS pixels with CSS perspective; world units only in legacy perspective={0} mode
perspective	number	32000	CSS-perspective distance in virtual pixels (matches voxcss). Larger = flatter foreshortening; set 0 for legacy orbit projection
stretch	number	1.0	Extra X scale on top of cellAspect

Vanilla JS

import {
  createGlyphPerspectiveCamera,
  createGlyphOrthographicCamera,
  createGlyphScene,
} from "glyphcss";
import { octahedronPolygons } from "@glyphcss/core";

const host = document.querySelector<HTMLElement>("#scene")!;

// Camera constructed first, then passed into the scene
const perspective = createGlyphPerspectiveCamera({
  rotX: 22,
  zoom: 50,
  distance: 3,
  stretch: 0.95,
});
const scene = createGlyphScene(host, { camera: perspective, mode: "solid" });

scene.add(octahedronPolygons({ center: [0, 0, 0], size: 1, color: "#ffcc44" }));

// Switch to orthographic:
const ortho = createGlyphOrthographicCamera({ rotX: 35, zoom: 50 });
scene.setOptions({ camera: ortho });

// Mutate camera state and re-render:
perspective.rotY = 45;
perspective.distance = 4;
scene.rerender();

Notes

• The default perspective camera matches polycss/voxcss: distance: 0, perspective: 32000, zoom: 0.65.
• rotX: 0 looks straight down the Z axis. Try 22 (degrees) for a slight downward tilt that gives the mesh visual weight.
• stretch: 0.95 counteracts over-stretching from cellAspect ≈ 2 on typical monospace fonts. Leave at 1.0 if you tighten line-height instead.
• Orthographic cameras ignore distance — use zoom to scale the mesh instead.
• GlyphCamera is the ergonomic default alias for GlyphOrthographicCamera. Use it for iso/diagrammatic scenes; use GlyphPerspectiveCamera explicitly for character or walkthrough scenes.
• Rotation units are degrees, matching voxcss/three.js. rotX=65, rotY=45 is the classic isometric-ish viewpoint. zoom is CSS pixels per world unit.
