float4::Normalize3
Syntax
float float4::Normalize3(); [25 lines of code]Normalizes the (x, y, z) part of this vector.
Note
This function ignores the w component of this vector, retaining whatever value was set there. This function fails silently. If you expect to receive an error message in case the normalization fails, use the Normalized3() function. This function operates in-place.
Return Value
The old length of this vector, or 0 if normalization failed. In the case of failure, this vector is set to (1, 0, 0, oldW), so that Normalize() function will never result in an unnormalized vector.
