Plane::normal
Syntax
float4 Plane::normal; [1 line of code]The direction this plane is facing at.
This direction vector is always normalized. If you assign to this directly, please remember to only assign normalized direction vectors.
Syntax
float Plane::d; [1 line of code]The offset of this plane from the origin.
The value -d gives the signed distance of this plane from origin. Denoting normal:=(a,b,c), this class uses the convention ax+by+cz = d, which means that:
If this variable is positive, the vector space origin (0,0,0) is on the negative side of this plane.
If this variable is negative, the vector space origin (0,0,0) is on the on the positive side of this plane.
Note
Some sources use the opposite convention ax+by+cz+d = 0 to define the variable d. When comparing equations and algorithm regarding planes, always make sure you know which convention is being used, since it affects the sign of d.
