rendercontext question

[Libor Capak]

hello,

i have trouble with RenderContext concept. Documentation is clear to me.
Idea of stateless nodes is nice, but i have problems with quite simple
issues.

for example scene node tree:

/car
   wheel1
   wheel2
   wheel3
   wheel4

there is spatial hierarchy. /car is root node in my RenderContext
instance. If I'd like to rotate wheels according to render context
concept - so then i have to flatten this hierarchy and create for each
wheel another RenderContext instance? By flattening i loose relative
position of wheels so i have to calculate local->world transformation
manually for each wheel render context. Or am i missing something?

thank you

     Hi,

     What I would do in that case is to isolate the "wheel state" in
some external variable such as "rotationFactor". Wheels objects then
render them accordingly, using an nAnimator that rotates them using that
variable.

     The renderContext used in the entire car has that variable set.
Car's trunk does not used it, but wheels do.

     Hope that helps.
