{"enrichment":{"faq":[{"a":"shader-sdf enables you to construct procedural geometry using signed distance functions directly in GLSL shaders. SDFs are mathematical functions that return the minimum distance from any point in space to a surface\u2014negative inside, positive outside. This representation lets you define complex 2D and 3D shapes through pure math rather than mesh data, making raymarching and real-time rendering highly efficient.","q":"What are signed distance functions in GLSL and how does shader-sdf use them?"},{"a":"shader-sdf provides the foundation for raymarching by letting you write SDF functions that describe your scene. Raymarching works by casting rays from the camera and stepping along each ray using the SDF to determine safe step distances. At each step, you query your SDF to find the distance to the nearest surface, advancing until you hit geometry or exit the scene. shader-sdf includes patterns for normal calculation and lighting integration.","q":"How do I implement raymarching for 3D scene rendering with SDFs?"},{"a":"Yes. shader-sdf supports applying boolean operations and smooth blending to combine shapes. You can perform union, intersection, and subtraction on SDFs, and use smooth variants that blend boundaries rather than creating hard edges. These techniques let you build complex procedural forms from simpler primitives\u2014for example, smoothly blending a sphere into a box or carving one shape from another.","q":"Can shader-sdf handle smooth blending and boolean operations on shapes?"},{"a":"shader-sdf provides a complete SDF primitive library covering 2D shapes (circle, box, polygon) and 3D primitives (sphere, box, torus, cone, capsule). It includes transformation code for domain repetition, twisting, bending, and other deformations. You can reference these building blocks directly in your shaders to rapidly prototype procedural geometry without writing distance functions from scratch.","q":"What SDF shader primitives and transformations does shader-sdf reference?"},{"a":"shader-sdf enables text effects and morphing animations by leveraging distance field rendering. You can apply glow, outline, and shadow effects by sampling the distance field at different thresholds. Morphing works by interpolating between two SDF representations over time, creating smooth transitions. Anti-aliased SDF rendering ensures clean edges even at high zoom levels, making text and animated shapes look crisp.","q":"How can I build text effects and morphing animations with distance fields?"},{"a":"Absolutely. shader-sdf is ideal for real-time graphics and generative visual effects because SDFs are computationally efficient\u2014they let you render complex geometry without storing mesh data. The MIT license permits both commercial and open-source use. Whether you're building interactive visualizations, procedural art, or game graphics, shader-sdf's mathematical approach scales well and integrates seamlessly into modern GPU pipelines.","q":"Is shader-sdf suitable for real-time graphics and generative visual effects?"}],"shadow_tags":["distance-field-rendering","procedural-geometry","raymarching-engine","shape-composition","shader-effects","glsl-primitives","implicit-surfaces","geometric-operations"],"summary_rewrite":"shader-sdf enables you to construct procedural geometry using signed distance functions directly in GLSL shaders.
