What is a .3DR file?
A .3DR file is a type of file that is made using a program called 3D Rad. This program is special because it's free and lets people create their own 3D games. Think of a .3DR file like a box that holds everything needed for a 3D game scene. Inside this box, you can find 3D objects, which are things like characters, trees, or cars, and each of these objects has its own settings or properties. But what makes these files really interesting is that they can also include instructions on how these objects should interact with each other. For example, if you have a ball and a hill in your game, the .3DR file can contain information that makes the ball roll down the hill when the game is played. This is done through something called physical constraints, which are like the rules of physics for the game.
To open a .3DR file, you need to use the 3D Rad program. This is the same program used to create the file, so it understands exactly how to display and work with the contents of the file.
Once someone has created a game or a 3D scene in 3D Rad and saved it as a .3DR file, they have a couple of options for what to do next. They can turn their project into a standalone game, which means it becomes its own program that can run on Windows computers. Alternatively, they can make it into an applet, which is a small program that can be added to a webpage. This way, people can play the game directly from their web browsers without having to download anything.
3D Rad and the .3DR files it creates are quite powerful. They support a lot of different features that are important for making games. This includes things like animation, which makes characters or objects move; artificial intelligence, which can make characters in the game seem smart and able to make decisions; visual effects, which can make the game look more interesting and realistic; and cameras and view modes, which change how players see the game. Creators can also add their own custom scripting, which means they can write their own code to make unique things happen in their games.
