Editing Real-time computer graphics (section)

=== Application stage ===
The application stage is responsible for generating "scenes", or 3D settings that are drawn to a 2D display. This stage is implemented in software that developers optimize for performance. This stage may perform processing such as [[collision detection]], speed-up techniques, animation and force feedback, in addition to handling user input.

Collision detection is an example of an operation that would be performed in the application stage. Collision detection uses algorithms to detect and respond to collisions between (virtual) objects. For example, the application may calculate new positions for the colliding objects and provide feedback via a force feedback device such as a vibrating game controller.

The application stage also prepares graphics data for the next stage. This includes texture animation, animation of 3D models, animation via [[Geometric transformation|transforms]], and geometry morphing. Finally, it produces [[geometric primitive|primitives]] (points, lines, and triangles) based on scene information and feeds those primitives into the geometry stage of the pipeline.
