画图代码如下:
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)
}
