# go-glmatrix

go-glmatrix is a golang version of [glMatrix](http://glmatrix.net/), which is ``designed to perform vector and matrix operations stupidly fast''.

## Usage

```go

package main

import (

	"fmt"

	glm "github.com/technohippy/go-glmatrix"

)

func main() {

	// config

	rotateQuat := glm.QuatFromValues(1, 2, 3, 4)

	translateVec3 := glm.Vec3FromValues(1, 2, 3)

	scale := []float64{4, 5, 6}

	rotateOrigin := []float64{7, 8, 9}

	// construct matrix

	transMat := glm.Mat4Create()

	glm.Mat4Identity(transMat)

	glm.Mat4Translate(transMat, transMat, translateVec3)

	glm.Mat4Translate(transMat, transMat, rotateOrigin)

	rotateMat := glm.Mat4Create()

	rotateMat = glm.Mat4FromQuat(rotateMat, rotateQuat)

	matrix := glm.Mat4Multiply(glm.Mat4Create(), transMat, rotateMat)

	glm.Mat4Scale(matrix, matrix, scale)

	negativeOrigin := glm.Vec3Negate(glm.Vec3Create(), rotateOrigin)

	glm.Mat4Translate(matrix, matrix, negativeOrigin)

	// transform position

	position := glm.Vec3FromValues(10, 20, 30)

	glm.Vec3TransformMat4(position, position, matrix)

	fmt.Printf(glm.Vec3Str(position)) // => vec3(1280, -290, -42)

}

```
