Detailed Description

We provide some geometry transformations for the builtin connectivities.

They are not meant as blueprints for future user code. Please implement p8est_geometry_t as you see fit.

Function Documentation

p8est_geometry_t* p8est_geometry_new_identity ( void )

Create a geometry structure for the identity transformation.

This function is just for demonstration since a NULL geometry works too.

p8est_geometry_t* p8est_geometry_new_shell	(	double	R2,
		double	R1
	)

Create a geometry structure for the spherical shell of 24 trees.

This is suitable for forests obtained with p8est_connectivity_new_shell.

Parameters:

[in]	R2	The outer radius of the shell.
[in]	R1	The inner radius of the shell.

p8est_geometry_t* p8est_geometry_new_sphere	(	double	R2,
		double	R1,
		double	R0
	)

Create a geometry structure for the solid sphere of 13 trees.

This is suitable for forests obtained with p8est_connectivity_new_sphere.

Parameters:

[in]	R2	The outer radius of the sphere.
[in]	R1	The outer radius of the inner shell.
[in]	R0	The inner radius of the inner shell.
