draw 3D object overlaying the scene

[rebelpn]

Hello everyone,

What I'd like to achieve is something similar to Blender's manipulator object. In a nutshell it's a 3D object - actually a set of 3D objects -, that overlays my regular 3D objects, like an on-screen-display. What I've tried so far: I created two empty scene nodes as containers: scene for my normal nodes and osd for the overlaying ones. Between BeginScene() and EndScene() I tried to render them, first scene and then osd as you can see here:

Code: Select all

 
driver->beginScene(true, true, SColor(0,100,100,100));
 
    scene->setVisible(true);
    osd->setVisible(false);
    scene_manager->drawAll();
 
    scene->setVisible(false);
    osd->setVisible(true);
    scene_manager->drawAll();
 
driver->endScene();
 

The two sets are rendered separately as I've expected but unfortunately the overlay effect does not happen, I mean if a node from scene is between a node from osd and the camera, it is drawn over the osd node

I'd appreciate any help with this issue.

To draw it on top, disable its depth test.

Thank you! It was really that easy
