Hello,

in the Simulink-Demos there is an example how to create a HUD-Text in vrml (with the v-Realm-Builder). What I want to know is, is it possible to create a HUD-Animation?
I want to do the animation the same way like I create a vrml scene. Stricty speaking, I want to simulate vehicle dynamics with the tachometer as a HUD.
Does anybody has an idea how to realize it?

Thank you for your help.

you can start with the vrtkoff_hud world, as present in the Simulink 3D
Animation demos. You will find a node named User, a node named HUDPos
and some routes between these two nodes. These nodes and routes together
make the HUD behave like a HUD - i.e., not to move when you navigate
through the world. You would probably want to use these as they are.

Then, there are children of the HUDPos node. The HUDOffset transform
positions the HUD to the lower left corner and by changing its
coordinates you can position it elsewhere. The children of this node
define how the HUD looks like. In the example, there's a single Shape
node with the geometry defined as Text. You will probably need to create
or find some tachometer device and place it instead of the Shape node.
There's a Clock object in the V-Realm Builder library - although not
exactly a tachometer, it can perhaps serve as a base for creating one.

Good Luck, Jan

Thank you very much!
That works perfect!
