Detailed Description

Options for generating an icosahedron mesh.

Member Function Documentation

project_to_valid_range()

void project_to_valid_range ( )

inline

Clamps all parameters to valid ranges.

This method ensures that:

• The radius is non-negative

Invalid parameters are automatically corrected to prevent geometric inconsistencies.
