3D Rad is an excellent tool for creating 3D animations not only for being a free program, but also because it doesn't require you to write any code to create outstanding 3D animations. The program is easy to use, it has a visualization window, where it shows the objects added to produce the animation. These objects are also listed in a frame, where each one is considered as an individual item.
The key of the program is to know how to work with the objects. You can adjust their parameters to enhance their aspect, e.g. you can add physical layouts, change the image, etc. The program includes some buttons called "Transformation buttons", which can be used to move a certain object to a preferred position, angle, etc. The objects can be also linked to other objects, e.g. you can add a Terrain object, a G-force object, a car object, and link the terrain and the G-force to the car (If the G-force or the Terrain weren't linked to the car, it would be floating when running the animation). You can add a camera and adjust the translation or rotation speed to follow an object.
The program includes different preloaded objects, but you can also include your own 3D models.
