float3::DistanceSq
Syntax
float float3::DistanceSq(const float3 &point) const; [7 lines of code]Computes the squared distance between this and the given point.
Calling this function is faster than calling Distance(), since this function avoids computing a square root. If you only need to compare distances to each other, but are not interested in the actual distance values, you can compare by using DistanceSq(), instead of Distance(), since Sqrt() is an order-preserving (monotonous and non-decreasing) function.
