Function Documentation

grvx_gradV()

void grvx_gradV	(	struct GrvxVec3D *	q,
		const struct GrvxPlanets *	planets
	)

Gradient of the potential at position q.

The gradient is evaluated at position q and the resulting vectors is stored in q.

Parameters

q	The position where the gradient is evaluated. The result overwrites this variable.
planets	Planets that generate the force field.

grvx_min_dist()

double grvx_min_dist	(	const struct GrvxVec3D *	q,
		const struct GrvxPlanets *	planets
	)

Minimal distance to any planet.

Parameters

q	The position of the missile.
planets	Planets that generate the force field.

Returns

Cosine of smallest angle between q and any planet.
