Member Function Documentation

bool Wizt::Pickable::isPickable

(

)

const [inline]

Tells whether this object may be picked by the mouse.

If false, this object will be invisible to mouse clicks.

int Wizt::Pickable::SubObjectBegin

(

VGLRenderContext &

Context

)

const [inline]

Function to be called by an object's render() routine to demark the beginning of a render section that can be picked independently of the rest.

Internally, a counter is incremented at each such call. This counter is then delivered to the Render object's pick() callback routine.

Note:

Maybe we also want an interface to explicitely set the object group ID.

Member Data Documentation

GLfloat Wizt::Pickable::white[4]

Color for displaying current object selection.

By default, it is white, but it may be changed to another color as well, although this is not necessarily a good idea because users might get confused.
