Using arrows keys to simply rotate an object?

[whyasky]

I've been experimenting with rotating an object in T3D.

At first, I setup the camera to orbit around the object.

But that didn't have the desired affect.

Instead, I'd like to rotate the object itself -

Leaving the camera in a fixed position.

So, far I've only been able to get it to rotate on the Z axis ... not X or Y.

Not sure if I'm trying the wrong approach or what --

 

  %txfm = %object.getTransform();  
 echo(" object starting transform=" @ %txfm );  

 // change the rotation based on number keys //  
  switch$(%direction)  
  {  
     case "LEFT":   %rotMod = "0 0 0.1";  
     case "RIGHT":  %rotMod = "0 0 -0.1";  

     case "DOWN":   %rotMod = "0 1 0";  
     case "UP":     %rotMod = "0 -1 0";  
  }  

  // create rotation matrix from radian angles    
  %rotTrans = MatrixCreateFromEuler(%rotMod);   

  // multiply against objects original transform  
  %newTransform = MatrixMultiply(%txfm, %rotTrans);  

  // set the transform     
  %object.setTransform( %newTransform );  

 

This seems to rotate it correctly on the horizontal axis (Z?)

But not the other axis's (guessing it X and Y not rotating)

Is this the correct approach -- Using a matrix multiply ?

Any ideas or examples of how to get it rotating in all directions?

in other words ... +/- X or Y or Z ... based on input.

I get the key mapping, etc ... just need a working example of the matrix math to use.
