GDMathLib.jl: Game development mathematic kit

Ever wanted to build a game or a game engine but stumbled on tricky math concepts ? You want to build your game but you don't have the time to learn about quaternions ? Then this package is for you. GDMathLib.jl takes away all the hassle and boilerplates of game maths and offer a high performance, ready to use toolkit.

Installation

julia> ]add GDMathLib

For the development version

julia> ]add https://github.com/Gesee-y/GDMathLib.jl

Features

Math Foundations

• Static Vectors (Vec2, Vec3, Vec4, etc.): Allocated on the stack so no GC pressure.
• Typed Hierarchy: Unified VectorType{T} system including Quaternion{T}.
• Optimized Performance: Uses @inbounds, @simd, and loop unrolling.

Utilities

• Functions: lerp, inverse_lerp, projection_matrix, etc.
• Transformations: The Transformation{N} struct lets you manage batched affine transforms efficiently, with manual matrix updates via update_transform_matrix!.

Coordinate Systems

• Work in alternative spaces like PolarCoord, SphericalCoord, CylindricalCoord, etc.
• Convert easily with ToCartesian(...).

Colors

• Built-in color palette (RED, GREEN, PURPLE, etc.) ready to use with other libraries.

Example

using GDMathLib

a = Vec3f(1,2,3)
b = Vec3f(7,5,9)

c = lerp(a, b, 0.5)
d = vnorm(a)
