Editing Graphics pipeline (section)

=== Application ===
The application step is executed by the software on the main processor ([[CPU]]). During the application step, changes are made to the scene as required, for example, by user interaction using [[input device]]s or during an animation. The new scene with all its [[geometric primitive|primitives]], usually triangles, lines, and points, is then passed on to the next step in the pipeline.

Examples of tasks that are typically done in the application step are [[collision detection]], animation, morphing, and acceleration techniques using spatial subdivision schemes such as [[Quadtree]]s or [[Octree]]s. These are also used to reduce the amount of main memory required at a given time. The "world" of a modern computer game is far larger than what could fit into memory at once.
