Talk:Geometry instancing

Example Image
An example image showing a scene that would benefit from Geometry Instancing or which used geometry instancing would help. Serialized 05:54, 8 January 2007 (UTC)

Assuming we are speaking about real-time instancing... An image wouldn't really help because the appearence is exactly the same. Anyway, the current definition is rather clear: if you have multiple copies of an object, you would ideally benefit from instancing. The only difference would be in performance. When it comes to an image to show how instancing works, this is something which needs some attention.

Not just mesh or real-time.
Instancing is more general concept than the article claims. It can be used with arbitrary geometry, not just meshes. It can also be used in offline applications, not just real time rendering. In ray tracing especially it can be done with almost anything. It can also be used in 2D. The key concept is that usually the bulk of geometry is shared, and only few extra properties are changed per instance (usually the transformation matrix, but few extra ones could also be employed). Also instancing is way older than Direct3D or OpenGL, and surely was used in 80s or earlier. Even 2D sprites that are used many times on screen at the same time, but share the same source, are in essence also instancing. 213.55.184.153 (talk) 07:57, 13 April 2019 (UTC)
