HP Card

The HP card creates a plate with a hyperbolic border.

On the Construct tab, in the Surfaces group, click the  Hyperbolic plate (HP) icon.



Figure 1. The HP - Create a plate with a hyperbolic border dialog.

Parameters:

S1
The origin (point at which the asymptotes intersect) of the hyperbolic border.
S2
The pole of the hyperbolic border.
S3
The point where the hyperbolic arc and straight edge intersect.
Max. triangle edge length (at hyperbolic border)
The maximum edge length on the hyperbolic border.

The hyperbolic border may require shorter mesh edges than those used for straight edges. The maximum edge length specified in the IP card can be overridden on the hyperbolic arc by setting Max. triangle edge length (at hyperbolic border).

Example of HP card usage

The plate with a hyperbolic border shown in Figure 2 is created using the HP card.
