This is the Kotlin port of [OpenGL Mathematics](http://glm.g-truc.net/) (*GLM*), written by [g-truc](https://github.com/Groovounet) ([repository](https://github.com/g-truc/glm)), a header only C++ mathematics library for graphics software based on the [OpenGL Shading Language (GLSL) specifications](https://www.opengl.org/registry/doc/GLSLangSpec.4.50.diff.pdf).
*GLM* provides classes and functions designed and implemented with the same naming conventions and functionality than *GLSL* so that anyone who knows *GLSL*, can use *GLM* as well in Kotlin and Java.
This project isn't limited to *GLSL* features. An extension system, based on the *GLSL* extension conventions, provides extended capabilities: matrix transformations, quaternions, data packing, random numbers, noise, etc...
This library works perfectly with *[OpenGL](https://www.opengl.org)* but it also ensures interoperability with other third party libraries and SDK. It is a good candidate for software rendering (raytracing / rasterisation), image processing, physic simulations and any development context that requires a simple and convenient mathematics library.
*GLM* is written entirely in Kotlin, but can be also used from Java. It is a platform independent library with no dependences other than [kotlin-unsigned](https://github.com/elect86/kotlin-unsigned) for unsigned support and [kotlin-test](https://github.com/kotlintest/kotlintest) for testing.
For more information about *GLM*, please have a look at the [manual](https://github.com/kotlin-graphics/glm/wiki) and the original [API reference documentation](http://glm.g-truc.net/0.9.8/api/index.html).

```kotlin
import glm_.vec2.Vec2
import glm_.vec3.Vec3
import glm_.mat4x4.Mat4
import glm_.glm
fun camera(translate: Float, rotate: Vec2): Mat4 {
val projection = glm.perspective(glm.PIf * 0.25f, 4.0f / 3.0f, 0.1f, 100.0f)
var view = glm.translate(Mat4(1.0f), Vec3(0.0f, 0.0f, -translate))
view = glm.rotate(view, rotate.y, Vec3(-1.0f, 0.0f, 0.0f))
view = glm.rotate(view, rotate.x, Vec3(0.0f, 1.0f, 0.0f))
val model = glm.scale(Mat4(1.0f), Vec3(0.5f))
return projection * view * model
}
