Calculate steepness or incline from 3 to 4 points (XYZ)

[vivienneanthony]

Hello

Do anyone have a idea to calculate steepness or incline from 3 to 4 points in a 3D(xyz) point?

I'm trying to calculate steepness to determine if i can or cannot place objects on a super steep elevation in a 3D game?

My initial thinking was to add up all angles then divide by 4? I'm not a match major and I am not finding any information online.

Hmm. The slope from (0,0,0) to (x,y,z) is z / sqrt(x^2+y^2). To compute the slop between two points, take the difference between the two points and then use the formula.
