Object Space - approaches for visible surface determination
The second approach as object-space that compares all objects directly along with each other inside the scene definition and removes those objects or portion of objects which are not visible. In terms of pseudo-code, we comprise:
for (each object in the world)
{
determine those parts of the object whose view is unobstructed (not blocked)
by other
parts of it or any other object;
draw those parts in the appropriate color;
}
This approach compares all of the n objects to itself and to another objects, and discarding unseen portions. Hence, the computational effort is proportional to n2.
Write a C-code that plots an object on the window and on the user's click of mouse on the window, the object starts rotating continuously until the user presses the mouse again.
