glua-SharpVector

A GLua implementation of Vector.

Featuring rigid optimization & precise calculations due to components being doubles.

My initial motive

The original idea was to write a GLua variant of Vector because in Lua numbers are stored as doubles (Double-precision floating-point format) while in the engine Vector's components are stored as floats (32 bits long; higher probability of precision loss on very small scales).

This script can be very handy if you need performant and high-precision vectors.

All pivotal details are concisely described/explained in the code.

All Vector functions are present. SharpVector() possesses the same argument overload as Vector().

Functions compatible with Vector:

• SharpVector:SetGModVector( vec )
• SharpVector:AddGModVector( vec )
• SharpVector:SubGModVector( vec )
• SharpVector:MulByGModVector( vec )
• SharpVector:DivByGModVector( vec )

Multiplication by Matrix is moved to SharpVector:MulByMatrix( matrix )

Extensions:

• Vector? SharpVector:ToGModVector( [vecOut] )
• SharpVector Vector:Sharpened()
• SharpVector? SharpVector:Lerp( sharpvecTarget, fraction[, sharpvecOut] )

Features

Functions that by design return new vector/angle/color/table as the result have the last argument as the output for the result (where reasonable). (Cross, ToColor, ToTable, Angle, AngleEx, Rotate)
