float4::ScaleToLength3
Syntax
float float4::ScaleToLength3(float newLength); [15 lines of code]Scales the (x, y, z) part of this vector so that its new length is as given.
This is effectively the same as normalizing the vector first and then multiplying by newLength.
Return Value
False if the length of this vector is zero, and the vector could not be scaled to the specified length.
