Coordinates introduction A large part of your game programming will be dealing with 3D coordinates. In this tutorial, we’ll cover the Mercator Projection and will learn how to implement its two variants. Two commonly used coordinate systems are the polar and Cartesian systems. When drawing to a screen or an off-screen image, X and Y coordinates are measured in pixels. 3km) I've tagged Java, but any algorithm format that's legible should work. The graph paper from eighth grade ("Cartesian coordinate system") placed (0,0) in the center with the y-axis pointing up and the x-axis pointing to the right (in the positive direction, negative down and to the left). This is a very common operation used in everything from video games to image processing. It is called the Cartesian coordinate system, developed in the 17 century by a French mathematician called René Descartes. Mar 24, 2022 · The NED coordinate is the expected value, I need to convert the ECEF to match 'close enough' as the NED value is limited to lower earth altitudes and this update is expected to include tracking of something like the moon ~384472. It is used to define points uniquely in a plane using two values: the radial distance from a fixed point (called the pole or origin) and the angle from a Definition of Earth-Centered, Earth-Fixed (ECEF) Coordinates: ECEF is a right-handed Cartesian coordinate system with the origin at the Earth’s center, and that is fixed with respect to the Earth (i. Coordinate Axes: When working with graphics, a coordinate system is essential for locating objects. Unfortunately, the axes for Java graphics are somewhat different. There are many types of coordinates systems but we shall be dealing with only one. The document outlines a syllabus for a course on Autodesk 3D Max and web scripting, detailing the content to be covered across four quarters. It includes topics such as 3D navigation, animation, multimedia embedding, JavaScript fundamentals, and web-based applications. The origin is in the upper-left corner of the drawing surface. Jul 9, 2025 · In this blog post, we will explore how to perform this conversion in Java. Apr 3, 2015 · Given a Cartesian (two-dimensional) coordinate system like the following: Is it possible - and if, how - to calculate a unique, sortable index for each field? This means that, using the x and y A Cartesian coordinate system library for Java Swing - andern/jcoolib We can reuse these operations with hexagonal grids. In the plane, two perpendicular lines are chosen and the coordinates of a point are taken to be the signed distances to the lines. The polar coordinate system represents a point in terms of a distance from a fixed point (the origin) and an angle from a fixed direction. This difference is illustrated by the figure below which compares the normal Cartesian coordinate system to the coordinate system used to draw within an applet. Jun 30, 2025 · This blog has covered the essential aspects of Java coordinates, from basic concepts to advanced best practices, enabling readers to efficiently use coordinates in their Java projects. The source code of this project is located at: https://github. The three axis are defined as follows: The prototypical example of a coordinate system is the Cartesian coordinate system. Jun 21, 2015 · Let's say that now I want to create a class "Point" with constructors, getters, a method that converts Cartesian Coordinates of a point into "Pixel Coordinates" and a method that print the point on the plane. Dec 11, 2013 · 4 There is a lightweight library written fully in Java. Contribute to uhoefel/coordinates development by creating an account on GitHub. You probably remember your mathematical coordinate axes system which utilizes an x -axis and a y -axis. The F Definition of Earth-Centered, Earth-Fixed (ECEF) Coordinates: ECEF is a right-handed Cartesian coordinate system with the origin at the Earth’s center, and that is fixed with respect to the Earth (i. The Java 2D API maintains two coordinate spaces: User space is a device-independent logical coordinate system, the coordinate space that your program uses. I'm trying to take a couple of hours out a day over my summer to learn java and sometimes it gets a little frustrating. Units are in meters. When drawing to a printer or other high-resolution device Aug 6, 2025 · Cartesian Coordinate System in Maths is a division of coordinate geometry where the location of a point in a plane or space is marked by a pair of numbers or three numbers. In this tutorial, we’ll compare records, POJOs, and arrays as potential ways to store these coordinates and explore the tradeoffs of each. The F The JavaFX coordinate system is based on a 2D Cartesian plane, where each point has an x -coordinate and a y -coordinate. Each section specifies the units, contents, and the number of periods allocated for teaching each topic. 3D coordinates provide a technique for locating objects in 3D. Jul 23, 2025 · Polar Coordinate System In contrast to Cartesian coordinates, the polar coordinate system expresses points in terms of their distance from a central point (the pole) and the angle formed with a reference axis (usually the positive x-axis). It is the coordinate I have some earth-centered coordinate points given as latitude and longitude (WGS-84). 4. Most of the time, we need to convert latitude and longitude to a 2D point to display. . CTS handles 4257 coordinate reference systems (3910 EPSG). 2 A Java library for handling coordinate systems.
