🎃 Browser-Based Projection Mapping

Pumpkin Puppet Studio

Turn real physical pumpkins into living, singing, talking characters. Featuring real-time 4-corner keystone mapping, monster voice DSP, and AtmosFX video projection.

How to Set Up in 3 Simple Steps

1

Connect Your Projector

Connect an HDMI projector to your laptop or cast a browser tab to Chromecast. Aim it directly at 1 to 3 real pumpkins.

2

Open Stage & Desk

Put /stage on the projector screen (pure pitch black canvas) and open /desk on your laptop screen.

3

Pin & Keystone Corners

Press M on the desk to view the alignment wireframe. Drag each pumpkin's 4 corners until the face fits the physical gourd!

📐

8×8 Bilinear Keystone Warping

Independent 4-corner perspective pinning for Left, Center, and Right pumpkins. Compensates for uneven pumpkin heights, angles, and distances.

🎙️

Monster Voice & Subwoofer DSP

Granular pitch shifter (-12 to +6 st), 240Hz pumpkin cavity resonance, tube distortion growl, and low-shelf subwoofer boost (< 90Hz).

🎬

Video Projection Show Mode

Drop any local 16:9 video file (e.g. AtmosFX Jack-O'-Lantern Jamboree). Automatically splits into 3 keystoned pumpkin faces with soft radial edge feathering.

🎭

Spoken Dialogue Conductor

Automated multi-pumpkin comedy banter routines, jokes, musical singing choreographies, and particle venting effects (flames, smoke, lightning, soul wisps).
