Sola Gratia series, Black & White Interactive 3D digital artwork / real-time WebGL rendering. The black and white version of the series, a meditative, interactive 3D experience that translates the theological concept of grace into a living, breathing digital cosmos. A preserved full-screen GLSL shader creates a sky background. 12,000 depth-sorted particles move through 3D space with noise-based turbulence, attracted by mouse/touch input, forming temporary communion lines in pure grayscale. OrbitControls allow free exploration of the infinite volume. Built with Three.js (r128 via CDN), custom ShaderMaterial, instanced particles, BufferGeometry, and Effect-like depth rendering. Single-file HTML, no external dependencies beyond Three.js.
