A cropped sensor view handing pan authority off to a physical gimbal

Two Pans, One Stick: Blending a Digital Crop Pan with a Physical Gimbal

A long-range zoom camera pans two ways at once — by sliding a crop window across the sensor, and by physically rotating the gimbal underneath it. Here’s how to make one joystick drive both so the operator never feels the seam, the maths of the handoff, and the per-axis bug that kept the gimbal rolling after the stick let go.

Three live Godot camera streams over RTP/UDP rendered by GStreamer clients

From Unity to Godot: Multi-Camera Streaming at 50 FPS with Async GPU Readback

After O3DE’s 18 ms frame-graph readback made 30 FPS streaming impossible, we tried Godot. It got us there — eventually. This is the full path from 105 FPS on nothing to 50 FPS per camera with three live RTP streams, including every wrong turn and every underdocumented Godot behavior we hit on the way.

O3DE rendering a ground plane from a camera spawned programmatically inside a headless Docker container

From Unity to O3DE: Multi-Camera Streaming at 1080p in a Headless Docker Container

Exploring whether O3DE can replace Unity as the render engine for a drone simulation that streams multiple 1080p camera feeds via GStreamer. From first scaffold to three live RenderToTexture pipelines in a single session.
