Functions

public function volume_tetra(vertices) result(volume)

テトラの体積計算。

Arguments

Type	Intent	Optional	Attributes		Name
real,	intent(in)			::	vertices(3,4)

Return Value real

public function insideJudgment_tetra(vertices, point) result(isInside)

任意の点がテトラの内部にあるかどうかを判定する。点でテトラを分割したそれぞれの体積の和が、元々のテトラの体積を上回れば、点はテトラ外部にある。 https://matcha-choco010.net/2018/03/14/point-in-tetrahedron/

Arguments

Type	Intent	Optional	Attributes		Name
real,	intent(in)			::	vertices(3,4)
real,	intent(in)			::	point(3)

Return Value logical
