Talk:Instancing

From DmWiki

I think this sentence is strange (probably wrong): "When skinning is involved, this can also refer to having different copies of the model in different poses, as well as different positions and orientations" Having different poses seems to refer to Tweening (old way to animate some objects without skinning (quake2 models did that for example)). I think Instancing and skinning are not really related since skinning usually implies anyway a reference model in a 'default pose'. That data is easily shared by all instances. Only bone orientations are different.

In instancing, you have one reference copy of the model, and render it in different positions and orientations throughout a scene or level. When you are using skinning, you can also have different bone orientations as well as different positions and orientations of the whole model. In both cases, only one copy of the model's data is stored in memory, and is never modified. It seems a natural generalization to me. Reedbeta 14:40, 11 Sep 2005 (CDT)
