[SOLVED] PlayerDummy's position and direction won't update if directly set model view matrix

[steve3d]

I'm trying to create AR project in unigine, and I'm using ARToolkit plus as AR sdk, artoolkit can give a direct model view matrix which can perectly used in unigine.

 

But I found another problem, which is if I created a new PlayerDummy, and directly set modelview matrix on it, the player's postion, direction won't be updated as new modelview matrix's value, then If I set this player to current player, all things are rendered wrong, shadows, gui..

 

So is this a bug of setModelview function of a Player. Or, this there any other way to set these properties with a given modelview matrix?

I can confirm this the following code has no effect on the viewport

int render() {
	Player player = Unigine::getPlayer();
        player.setControlled(0);
	mat4 mv = player.getModelview();
	
	mat4 out = mv*translate(10,0,0);
	player.setModelview(out);

	player.flushTransform();
	return 1;
}

am I missing something? [edit] I am running in game mode[/edit]

just googled some articles about this, seems there is no easy way to get eyepos/dir/up from modelview matrix.

 

and I've found one about how to calculate on this, always geting position of vec3_zero..

 

waiting unigine guys or some math master to help me on this.

Danny, Just set inverse of your modelview matrix to the player world transformation.

 

player.setWorldTransform(inverse(out));

Or you can use player's offset matrix to simulate small movements.
