the program has following functions:
Button “Cube” is used to change the cube’s visibility. Likewise, button “
Triangle” is used to change the Tetrahedron’s visibility. Please Use left mouse
button to click button.
Button “Menu” is used to decide whether the right click of your mouse will pop
up menu or not, because I also use right button to scale the geometry in the edit
scene. There are four kinds of menu (Projection: +X, +Y, +Z; Scene: Read, Save;
Light: Point, Direction, Direction; Shade: Flat, Smooth).
You can press key ‘x’,’X’, ‘y’,’Y’, ‘z’,’Z’ to select three orthographic
projections, or you can select it by menu.
Camera is represented by sphere with three axes. You can translate the sphere in
one of three orthographic projections; the camera view port will change
accordingly.
Light is also represented by sphere. If it is directional or spot light, you can see a
vector with it.
You can use left or middle button of mouse to pick the objects in editing
viewport. Left button is also used to rotate the object. Middle button is also used
to translate the object.
