Geometry

Geometry classes define the design parameterization. They should implement:

sample_prior(n)
decode(params)
encode(raw_geometry)
validate(params)
plot(params)

Responsibilities

• sample_prior(n): draw initial design parameters.
• decode(params): convert parameters to raw geometry or mesh form.
• encode(raw_geometry): fit or extract parameters from raw geometry.
• validate(params): return a feasibility mask for parameter-level checks.
• plot(params): create a human-readable geometry visualization.

Current Geometry Types

• CSTAirfoilGeometry: Kulfan/CST airfoil parameters.
• SuperWingParameterGeometry: SuperWing global planform, spanwise, and CST parameters.

Design Guidance

Keep geometry differentiable when possible. If geometry construction is differentiable, DFlow and post-optimization strategies can optimize through surrogate physics and geometry transforms.
