Detailed explanation of the technical principles of the Python framework in Java class libraries

The Python framework is a Java class library used for geometric calculations and graphic operations in 2D and 3D spaces. It provides a simple and powerful way to handle and manipulate geometric objects such as points, lines, rectangles, polygons, circles, ellipses, etc. The technical principles of the Python framework mainly involve the following aspects: 1. Points and vectors: The Python framework represents and manipulates points based on the concept of vectors. Vectors can represent attributes such as position, direction, and movement in 2D or 3D space. By using vectors, the Python framework can perform operations such as point translation, rotation, and scaling. 2. Geometric objects: The Python framework provides many geometric objects that can be represented and manipulated, such as line segments, rectangles, polygons, circles, and ellipses. Through these geometric objects, various geometric calculations can be performed, such as calculating the distance between two points, determining whether two objects intersect, and so on. 3. Matrix transformation: The Python framework utilizes matrix transformation to transform points and geometric objects. These transformations include translation, rotation, scaling, and shearing. By matrix transformation, a geometric object can be transformed from one coordinate system to another. 4. Graphic rendering: The Python framework supports rendering geometric objects onto the screen. It provides a graphics rendering engine that can convert geometric objects into images or vector graphics and display them on the screen. In this way, developers can easily draw various graphics and display them to users. The following is an example of Java code that uses the Python framework for geometric calculations: import com.hackoeur.jglm.Vec3; public class GeometryCalculator { public static void main(String[] args) { Vec3 pointA = new Vec3(2, 3, 1); Vec3 pointB = new Vec3(5, 7, 1); //Calculate the distance between two points double distance = pointA.distance(pointB); System. out. println ("Distance:"+distance); //Translation point A Vec3 translatedPoint = pointA.add(new Vec3(1, 2, 0)); System. out. println ("Coordinates after translation:"+translatedPoint); //Create a rectangular object Rectangle rectangle = new Rectangle(4, 3); //Calculate the area of a rectangle double area = rectangle.getArea(); System. out. println ("Area of rectangle:"+area); //Check if two rectangles intersect boolean intersects = rectangle.intersects(new Rectangle(2, 2)); System. out. println ("Intersects:"+Intersects); } } Through the above example, we can see how to use the Python framework for geometric calculations and operations. This framework provides many convenient methods and classes, allowing developers to easily handle various geometric objects and operations. The Python framework can play an important role in game development, graphics processing, and other applications involving geometric calculations.
