BLOKS Fundamentals FFT Spectrum Analysis Explained Understanding how sound becomes usable frequency data for audio-reactive shaders, music visualizers, and real-time audiovisual systems. FFT spectrum analysis is one of the core technologies behind modern audio-reactive visuals. It allows software to break sound into frequency bands so shaders, visualizers, and interactive systems can respond to bass, mids, […]
BLOKS Fundamentals Signed Distance Fields Explained Understanding the mathematical geometry system behind raymarching, procedural graphics, and modern shader art. Signed Distance Fields, often called SDFs, are one of the most powerful concepts in modern procedural graphics. They allow geometry to be described mathematically through distance calculations rather than traditional polygon meshes, enabling raymarching, procedural worlds, […]
BLOKS Fundamentals The Mathematics of Procedural Graphics How equations, noise, geometry, shaders, and GPU computation generate immersive visual worlds in real time. Procedural graphics use mathematics instead of pre-made assets to generate images, animation, geometry, textures, and entire environments. Modern GPUs can execute millions of mathematical operations simultaneously, allowing artists and developers to create immersive […]
