magic-pixels examples

Each example is a single HTML file that imports the library as an ES module from ../magic-pixels.js, a copy of the current build. Run npm run build:examples once to create it, then serve this folder with any static file server (a browser can't load an ES module over file://) and open a demo, or read the source to see how it uses the library.

• Spinning cube

  The smallest scene: a box, a normal material, a perspective camera, a render loop.

• Scene graph orbit

  A sun, a planet and a moon, orbiting through parent/child transforms and empty Object3D pivots.

• Custom shader material

  A hand-written GLSL vertex/fragment pair displaces and colors a sphere from a time uniform.

• Quaternion slerp

  Two cubes swing between the same orientations: one slerps its quaternion, the other lerps Euler angles and wobbles.

• Typed vertex attributes

  The same box geometry stored as Float32Array and as quantized 8/16 bit integers, side by side, rendering identically at a third the vertex memory.

• Textures

  The same gradient texture with colorSpace: 'linear' and colorSpace: 'srgb', showing why the GPU needs to know which one a texture is.

• Material render state

  Three transparent planes slide through each other and always blend correctly however their draw order changes, and a single-sided plane disappears for half of its spin.

• Lights

  A DirectionalLight circling like a low sun and a PointLight orbiting with a glowing marker as its child, read by a hand-written Lambert shader through the built-in light uniforms.
