float3::Neg

Syntax

float3 float3::Neg() const; [4 lines of code]

Returns a copy of this vector with each element negated.

This function returns a new vector where each element x of the original vector is replaced by the value -x.

Return Value

float3(-x, -y, -z).

Performance

4.105nsecs/call ≈ 243.59M calls/second ≈ 4.06M calls/frame (@ 60fps).
