[Solved]Getting the "positioning point" of a model

NeWsOfTzzz · Post by **NeWsOfTzzz** » Sun Jul 19, 2009 12:00 pm

A 3d model has always a point, where the position is related to. Since I don't know the name of that point I couldn't search for my question

So first question: What's the name of this positioning point?

Second and important question: How can I get this positioning point in IrrLicht? I'm using a bounding box so I can calculate distances, for example to the ground. I tried using boundingBox.getCenter(), but then I've seen that this positioning point often is NOT the center.

Kind Regards and thanks for your help,
René

PS: I've just seen the transformedBoundingBox is using absolute position, so I could calculate it with the original sceneNode->getPosition(). So I think second question is answered (I'll recode it now and test it), but I'd still like to know the name of this positioning point, so I can maybe reposition it in 3ds max?

That point is called origin, as in origin of model. You can get it by calling node->getPosition() or getAbsolutePosition() if your node is parented. Models are positioned using their origin.

most modelling applications call it the pivot, the position around which the transformations on the mesh apply.

Ty, found out how to move the pivot now in 3ds max

May be closed.

just rename the thread to [solved] and it will be fine.
