Howdy,
Well, it looks like a SceneHookData() may not work. The documentation says this: "This is a data class to register a function that will be called on every scene prepare, for example before redraw and before rendering." From what that says, it gets called before drawing, so that doesn't sound like it could work.
I'm curious though, is it possible to call an object's Draw() function from within a tag's Draw() function, and would it be safe to do that? I mean if both tag and object Draw() functions are normally called from within the same thread, it should be safe, right? Maybe? It sounds logical, but then I don't have enough experience with C++ to know for sure.
Adios,

You should really test when Draw is called. What the docs mention is about the Execute function.
Theoretically it should be safe. However first you must get a pointer the corresponding ObjectData instance for your object. The safest way to do it is probably by using the message function with MSG_RETRIEVEPRIVATEDATA. And return/send whatever data you need. You could actually send the BaseDraw Pointer and call the object draw function as reaction on the message.

You can also get the node data using something like this (not illegal and it works) :
MyObject* myo = static_cast<MyObject*>(obj->GetNodeData());
This allows you to call methods in your ObjectData. Just make sure to check for NULL and heed the advice about virtual functions.

Howdy,
Well, thanks for all the help, but I may end up abandoning the idea.
I noticed that the tag's Draw() function gets called three times, and that seems a bit too often to be branching out to each joint just to draw them on top of the polygon mesh. :o(
Anyway, I am curious to know how the bones are doing it, though.
Adios,

GetNodeData(), thanks for the hind. I was looking for something like this, but could not find it.
I still suggest that using a SceneHook will work. It allows more control over when the drawing happens ( highlight pass ) and the draw function should always be called. I'm convinced that bones are drawn this way.
It would be nice now to know for sure... Mikael ? David ?

I may give that a try, but maybe for the next update of the plugin. ;o)

It's surely a hack to call the object's Draw() function from the tag's, but I can't see how it could be dangerous. More like code reuse...
The Scenehook solution might be the simplest, though, provided that its Draw() function is always called after objects'. -

Dan,
Did you ever find a solution here and what was it?
I am looking into something similar for my bones while some other related features are added.
If you went with a SceneHook, how do you do the drawing? Do you recurse the document's objects for you own and draw them then?
Thanks!
Robert

Actually, I haven't tried it anymore, and just went on to other things.

Hello Dan,
Nothing huh?
Well, if I find a way, it will be posted here.
Thanks!

Howdy,
Cool, good luck with it.
It just seemed like too much to do, and there were more important things for me to solve.

Howdy,
OK, I think I'm going to give this a shot again, but I have no idea how to use a scene hook or how to even set one up. There is no example of a SceneHookData plugin in the SDK project. I've found some bits and pieces of code here on the cafe, but not a complete example.
I'm going to see if I can figure this out from the bits and pieces, but I'll welcome any complete example anyone is willing to share.
Adios,

Howdy,
Well, I figured out how to set up the SceneHookData and it works!
Seems that if I draw in screen coordinates using the 2D drawing functions, it draws on top of the polygon mesh using the SCENEHOOKDRAW_ACTIVE_PASS flag. Since I'm only drawing lines anyway, that works out great.

Great news, Dan!
Please post a screenshot so we can see the cool results (this could be over at CGTalk if you like).

Here is the result:
I had to write my own dotted line drawing routine, though, using BaseDraw's Point2D() function.

Very nice, Dan. I may have to speak with you on how you accomplished this with a SceneHook in the future.
Take care,
