3d scene draw a 2d image.

Such as a bullet hit the wall, posted on the wall of the crater.
What is the function to be used in SIO2 engine?

My question is:

1 3d scene draw a 2d image. sio2 whether to provide this interface?
2 The blood of the head characters . use Billboard？
3 How to use this function?
void sio2ObjectBillboard( SIO2object *_SIO2object,
vec3 *_vec ); The second parameter is what? The Camera Position ?

thanks!

You don't have to really call this function just set the SIO2_OBJECT_BILLBOARD flags and SIO2 will do all the dirty work for ya

ok!I know it! thank you !

This function is very useful!
sio2EnableState( &sio2ResourceGetObject( sio2->_SIO2resource,
YOUROBJECT)->flags,
SIO2_OBJECT_BILLBOARD);

I want to ask another question:
In the 3D environment.
Such as a car hitting the wall, an explosion occurred.Because the explosion map is a 2d image.
How do I paste an explosion map?

I know that the first access to the car's location,How to explode at this location paste pictures?

Just get the contact points from bullet... I already paste the code on the forum somwhere just dig a bit:)
