The author shares the full initial prompt given to Astra: generate a 3D model from a reference dragon image as a procedural signed distance function in Inigo Quilez's style, build a library of basic shapes and combination operations, learn SDF modeling best practices from Inigo's articles and video tutorials, critique renders visually via a GLSL/ShaderToy-style renderer with sphere tracing, and work coarse-to-fine with selectable detail levels.
