Straal

Straal is a rust-based linear algebra library, mainly aimed at applications in rendering and physics. In the future, there may be additions to also do other types of calculations.

Supported Types:

Vectors of various sizes, both normal and Integer variants:

• (I)Vec2-4 in i32, i64, f32 and f64

Square Matrices of Various sizes:

• Mat2-4 in f32 and f64

Quaternions

• Quat in f32 and f64

Features:

• In an attempt to follow GLSL, all "standard" operations are done through operator overloads
• Very easy to use with Glium
• Matrices have a few extra operations, such as transpose, determinant, adjoint, and inverse.
• Matrices also have a few ease of use functions to make rotations and translations much easier to work with.
• Lots of cross-casts are offered through the From trait, to easily get from one type to another

Things to watch out for:

• Just like GLSL, multiplying 2 vectors with the * operator, does not give the dot product, but a component-wise product.
• The matrices are row-major, this is not the same as GLSL, uniforms are automatically converted to column major as they are passed into OpenGL, but be careful with it.

To Do:

• A bunch of built-in opengl functions, like reflect, refract, mix, clamp, etc.
• Complex Number type
• Potentially a Geometry (primitives, tests, etc.) component.
