I finally decided to try 3D. This is a simple demo of a little engine I put together that can render any OBJ file, at any angle and in any lighting. • Drag the joystick to rotate the helicopter. • Rotate the sun/moon dial to change the time the sun rises and sets. • Adjust the time speed slider to change how quickly the day passes. • Move your mouse to the top right to change the RGB color of the helicopter.
