glua-SharpVector

A GLua implementation of Vector with rigorous optimization & high precision because Lua numbers are 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 default Vector functions are present. SharpVector() features 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 )

Extensions:

• Vector? SharpVector:AsGModVector( [vecOutput] )
• SharpVector Vector:Sharpened()
• SharpVector? SharpVector:Lerp( sharpvecTarget, fraction[, sharpvecOutput] )

Features:

• SharpVector:Normalize() returns the length in addition.
• Functions returning a new object have additional final argument as the output for it (where reasonable).
  _{(Cross, ToColor, ToTable, Angle, AngleEx)}
• SharpVector:Rotate has a second argument as the output for transformation.
