From first surface to Go Live
A practical first projection: align with a test pattern, add media, tune the surface, and send a clean browser output to your projector.
Projektor field notes
Read the signal.
Practical projection workflows, rendering notes, and live-control patterns from the open browser instrument. Written to use beside the projector, not filed away for later.

Why homography fixes the diagonal kink
Corner pinning is a projective geometry problem. Here is why two ordinary triangles bend the image, and how Projektor keeps a quad perspective-correct.
Shader lab9 min
Build an audio-reactive GLSL visual
Turn browser-local microphone analysis into bass, mid, high, level, and beat uniforms, then shape those signals into a visual that stays playable.
Live workflow10 min
Run a set with Looks, MIDI, and beat sync
Turn an aligned project into a playable cue list with named Looks, crossfades, learned MIDI controls, and deliberate beat-driven changes.
Open systems11 min
Shareable project URLs meet agent control
Projektor exposes a project as a portable URL and the editor as an MCP control surface. Together they make a mapping setup forkable and scriptable.
Enough theory
Put a surface on the stage.
