import . "../pt"
func main() {
scene := Scene{}
material := GlossyMaterial(HexColor(0xFCFAE1), 1.5, Radians(20))
mesh, err := LoadOBJ("sponza.obj", material)
if err != nil {
panic(err)
}
mesh.MoveTo(Vector{}, Vector{0.5, 0, 0.5})
scene.Add(mesh)
scene.Add(NewSphere(Vector{0, 20, 0}, 3, LightMaterial(White, 100)))
camera := LookAt(Vector{-10, 2, 0}, Vector{0, 4, 0}, Vector{0, 1, 0}, 45)
sampler := NewSampler(4, 4)
renderer := NewRenderer(&scene, &camera, sampler, 960, 540)
renderer.IterativeRender("out%03d.png", 1000)
