 There are no classes in GLSL, but they can be simulated using structs:
 <lang>
-public class Rectangle{
+struct Rectangle{
-    public double width;
+    double width;
-    public double height;
+    double height;
+};
-    public Rectangle(double width, double height){
+Rectangle new(double width,double height){
-        this.width = width;
+    Rectangle self;
-        this.height = height;
+    self.width = width;
-    }
+    self.height = height;
-    public double area(){
-        return this.width*this.height;
+    return self;
+}
-    }
-    public double perimeter(){
+double area(Rectangle self){
-        return (this.width+this.height)*2.0;
+    return self.width*self.height;
-    }
+}
+double perimeter(Rectangle self){
+    return (self.width+self.height)*2.0;
 }

 The task describes several concepts concerning class methods before giving some task requirements.  The following code satisfies the task requirements.  The concepts described however, are more involved.  A discussion of these concepts follows.
