For a feature in an upcoming project of mine, I've created a large animated display that bounces around, along with culling. The sphere will not be used in the final product, it just demonstrates the technology.
There is some screen tearing, but I have ideas to get around that if its too noticeable in the final product. This uses a background plane for the "sprite", so it isn't actually a real sprite. It relies on the level drawing routine, which tracks the object and follows it with one of the planes just like how the camera tracks and follows Sonic. This is how the culling is done.
The object tracking code is created by @Katsushimimimi.
I'll be using this feature for an upcoming project of mine, running on the engine used for Sonic: To Be A Star, created by @Katsushimimimi. This project has no relation to Sonic: To Be A Star or Sonic Debut, but may reuse features from both projects.
