This is an approach to development that allows you to quickly test ideas by changing the program on the fly while it is running. I demonstrate how the image-based approach works with a simple example. Almost from scratch, without restarting the program, we will create a small 3D world of several objects and add animation for them. And all this without restarting the program. On the fly!
