GoCavans是一个golang封装的3D模型动画演示库，提供了gltf、obj、fbx等多种模型格式加载，支持天空盒、灯光和脚本动画编辑等功能。相比于[g3n](https://github.com/g3n/engine)等3D框架，GoCavans 更轻量并且简单易用。

## 运行demo

如果你想快速体验，可以运行 [demo](https://github.com/shikanon/gocanvas/blob/main/docs/run-demo.md)示例，他是非常简单的:

[example](./example)

![](https://github.com/shikanon/gocanvas/blob/main/docs/demo.png)

## Usage

```go

import (

	"fmt"

	"net/http"

	gocanvas "github.com/shikanon/gocanvas/pkg/canvas"

)

func render(w http.ResponseWriter, r *http.Request) {

	app := gocanvas.NewApplication(w)

	scene := app.Scene()

	// 创建一个摄像机

	camera := gocanvas.DefaultCamera()

	// 创建一个天空盒

	skybox := gocanvas.DefaultSkybox()

	// 创建一个灯光

	light := gocanvas.DefaultLight()

	// 创建一个模型

	model, err := gocanvas.LoadGLTFModel("./assets/corvette_stingray/scene.gltf")

	if err != nil {

		fmt.Fprintln(w, err.Error())

		return

	}

	// 加入到场景中

	scene.AddCamera(camera)

	scene.AddSkyBox(skybox)

	scene.AddLight(light)

	scene.AddModel(model)

	// 渲染

	err = scene.Render()

	if err != nil {

		fmt.Fprintln(w, err.Error())

		return

	}

}

func main() {

	http.HandleFunc("/", render)

	http.Handle("/src/", http.FileServer(http.Dir("")))

	http.Handle("/assets/", http.FileServer(http.Dir("")))

	http.ListenAndServe(":8080", nil)

}

```
