Please take note that all vertices and indices will be duplicated, this call will basically create a totally new SIO2object in local memory and video memory. This is indeed an expensive call. Only use sio2ObjectHardCopy for animated SIO2object or when the SIO2object use soft body physic. For the rest of the cases, please use sio2ObjectSoftCopy as much as you can.

SIO2object* sio2ObjectSoftCopy	(	SIO2object *	_SIO2object,

	)

Create a soft copy of an SIO2object, commonly called "instance" in SIO2. Please take note that the SIO2object passed in parameters to this function need to be a "master" SIO2object, in other words not another instance.

In addition, to have the new SIO2object working in worldspace you will have to assign the SIO2transform parameters and specify where this new SIO2object will be located in world space. In the case that the new SIO2object is using physic, you will have to manually add it to the SIO2physic world of your choice. All variables will be duplicated and ready to be added in a SIO2physic handle.

Also in the case of duplicating a physic object of the type SIO2_PHYSIC_TRIANGLEMESH or SIO2_CONVEXHULL, you will have to map (sio2MapBuffer) the parent VBO buffer before sending the new SIO2object to the sio2PhysicAddObject function.

Please take note that soft body objects or animated objects cannot be duplicated with this function. You will have to use sio2ObjectHardCopy for this type of SIO2object.

Update the SIO2object->type. Basically there's 3 type of SIO2object in SIO2, SIO2_OBJECT_SOLID, SIO2_OBJECT_TRANSPARENT and SIO2_OBJECT_ALPHA_TESTED, all of them require a different type of sorting when rendered. This function will analyze the SIO2object and its SIO2material(s) and determine in which category the SIO2object should be used by the sio2ResourceRender function.

_SIO2object: A valid SIO2object pointer.
