Simple go library for decoding binary and ASCII STL files as well as binary encoder.
Reading triangle vertices of a binary or ASCII STL file
package main
import (
"fmt"
"log"
"os"
"neilpa.me/go-stl"
)
func main() {
f, err := os.Open("path/to/mesh.stl")
if err != nil {
log.Fatal(err)
}
mesh, err := stl.Decode(f)
if err != nil {
log.Fatal(err)
}
for _, face := range mesh.Faces {
fmt.Println(face.Verts)
}
}See also stlbox for an example of calculating the bounding box.
