# Corner Finder Specification

Corner Finder Specification defines which in-plane geometry corners are detected before corner snapping or corner refinement is applied.

This object corresponds to tidy3d.CornerFinderSpec (opens new window).

Corner detection is used by the corner_finder controls in layer refinement.

# Medium

medium: Medium type considered by the corner finder.

  • Options: Metal/Dielectric/All
  • Default: Metal

# Angle Threshold

angle_threshold: Angle threshold used to qualify a vertex as a corner.

  • Type: floating-point number

# Distance Threshold

distance_threshold: Optional distance threshold used to disqualify vertices that are too close to neighboring vertices.

  • Type: floating-point number

# Concave Resolution

concave_resolution: Number of steps used to determine dl_min for concave features.

  • Type: integer

# Convex Resolution

convex_resolution: Number of steps used to determine dl_min for convex features.

  • Type: integer

# Mixed Resolution

mixed_resolution: Number of steps used to determine dl_min for mixed concave-convex features.

  • Type: integer

NOTE

If a corner resolution field is empty, the corresponding dl_min reduction is not applied.
