geiss-port
geiss-port is a Graphics, 3D & shaders skill for AI agents, published by ad-repo in the nullplayer repository on GitHub. Skillspace rates geiss-port D (68/100) and it passed the safety scan; the rating is based on static analysis only.
Implementation reference for NullPlayer's Geiss visualization engine — the BSD-3-Clause port of Ryan Geiss's Win32/DirectDraw/Winamp-2 visualizer onto macOS as a ProjectM-peer engine. Covers the CGeissCore C ABI, upstream-vs-port file split, indexed-framebuffer + palette-LUT render pipeline, Accelerate-based spectrum push, threading model, persistence, and the architectural deviation around upstream/main.cpp. Use when modifying anything under Sources/CGeissCore/, GeissEngine.swift, the spectrum/PCM path in VisualizationGLView for Geiss, or the engine-conditional Geiss menu in ModernProjectMView.
