class EBGeometry::ConeSDF< T >
Signed distance field for a finite cone.
The cone tip is at m_tip and the body opens in the -y direction, so the base disc lies at m_tip + (0, -m_height, 0). The full opening angle a_angle is the tip-to-tip apex angle; internally the half-angle is encoded as m_c = (std::sin(half_angle), std::cos(half_angle)). The base radius equals m_height * std::tan(half_angle) = m_height * m_c[0] / m_c[1].
The SDF is negative inside the solid cone (including the base disc) and positive outside. By default the tip is at the origin, the height is 1, and the full opening angle is 45°, giving a base radius of std::tan(22.5°) ≈ 0.414.
