Parameters:

TriCoords (array_like) – Coordinates of the three vertices of the triangle in the format np.array([[a, b, c], [d, e, f], [g, h, i]])
xlim (array_like) – 2 element array of the lower and upper bounds of the box in the x direction [xmin, xmax]
ylim (array_like) – 2 element array of the lower and upper bounds of the box in the y direction [ymin, ymax]
zlim (array_like) – 2 element array of the lower and upper bounds of the box in the z direction [zmin, zmax]
TriNormal (array_like, optional) – Triangle normal vector, by default None. Will be computed if not provided.
BoxCenter (array_like, optional) – Coordinates of the center of the box, by default None. Will be computed if not provided.

Returns:

intersection – True if there is an intersection, otherwise False.

Return type:

bool
