DreamSketch: Early Stage 3D Design Explorations with Sketching and Generative Design
summary
A sketch-driven interface converts rough strokes into movable interface objects, feeds topology optimization that minimizes volume for aluminum, and returns many geometry variants: one variable → 4 results, two → 16, three → 64. Generation time depends on voxel resolution and iterations: coarse 30 iters ≈ 80s, finer 50 iters ≈ 20min; another case is ~2 minutes per solution (so 16 solutions ≈ 32min, or parallelize). Designers and engineers (3 and 3 in the study) explore and 3D print the generated forms as usable prototypes.
