In jefferis/nat: NeuroAnatomy Toolbox for Analysis of 3D Image Data

Find the coefficients of the plane equation

Description

Find the coefficients of the plane equation

Usage

plane_coefficients(p, n)

Arguments

p	A point on the plane (or N x 3 matrix of multiple points)
n	vector normal to the plane (or N x 3 matrix of multiple vectors)

Details

Both p and n can accept multiple points/vectors to calculate many planes at once.

Value

a matrix with 4 columns a,b,c,d where ax + by + cz + d = 0

# projection neurons enter mushroom body calyx
mbe=plane_coefficients(p=c(207, 102, 142), n=c(.6,-0.1,0.3))
