用Go语言绘制Go语言地鼠吉祥物

　　Go 语言是谷歌 2009 发布的第二款开源编程语言。Go 语言专门针对多处理器系统应用程序的编程进行了优化，使用 Go 编译的程序可以媲美C或 C++ 代码的速度，而且更加安全、支持并行进程。但 Go 语言除了擅长处理服务器端任务外，它还可以用来做图。

package main  import (     "log" "github.com/fogleman/pt/pt" )  func main () {     scene := pt.Scene{}     wall := pt.SpecularMaterial (pt.HexColor (0xFCFAE1), 2)     scene.Add (pt.NewSphere (pt.Vector{4, 7, 3}, 2, pt.LightMaterial (pt.Color{1, 1, 1}, 1, pt.NoAttenuation)))     scene.Add (pt.NewCube (pt.Vector{-30, -1, -30}, pt.Vector{-8, 10, 30}, wall))     scene.Add (pt.NewCube (pt.Vector{-30, -1, -30}, pt.Vector{30, 0.376662, 30}, wall))     material := pt.GlossyMaterial (pt.Color{}, 1.5, pt.Radians (30))     mesh, err := pt.LoadOBJ ("examples/gopher.obj", material)     if err != nil {         log.Fatalln ("LoadOBJ error:", err)     }     mesh.SmoothNormals ()     scene.Add (mesh)     camera := pt.LookAt (pt.Vector{8, 3, 0.5}, pt.Vector{-1, 2.5, 0.5}, pt.Vector{0, 1, 0}, 45)     pt.IterativeRender ("out%03d.png", 10, &scene, &camera, 2560/4, 1440/4, -1, 16, 4) }
