Geometric visuals are built by combining one SDF shape with boolean operations, then imposing symmetry, then composing the frame

The build order for geometric visuals follows a specific sequence: (1) Start from a single sdf-shape. (2) Combine shapes using boolean-sdf (union/subtraction) to build compound geometry. (3) Impose order through mirror and radial-symmetry, or lay a tiling-repeat grid. (4) Compose the frame using visual-balance and rule-of-thirds — placement is the primary expressive lever in geometric work. A single off-center accent against a symmetric field carries more visual weight than elaborate geometry with poor placement. The order matters: composing before adding symmetry usually fails because symmetry changes placement relationships.

Examples

GLSL: sdCircle - sdBox (boolean subtract) → mirror(abs(uv)) → place slightly off-center for tension. Hydra: shape(4).diff(shape(8,0.2)) → .kaleid(4) → scroll to thirds.

Assessment

Describe the four-step build order for a geometric visual. Why does the text say ‘geometric work lives or dies on placement’? Demonstrate with a one-sentence example of how a placement change (not a shape change) could transform the image.
