Draw, move, and scale shapes with some C++ code and OpenGL (Open Graphics Library). Most if not all Windows computers already have OpenGL support. Compile and edit the C++ code with free software for Windows called Bloodshed Dev-C++. After downloading it, look for the folder containing example source code to display a basic OpenGL window.
keen observation. opengl is typically a fixed camera. move the objects about the scene. imagine placing a box a foot in front of you. the only thing you can view is what is in that box. as you pass objects through the coordinates inside that box they become visible. then when they pass out of the box they are no longer visible anymore. that box defines your scene space.
