I'm trying to render a billboard texture which is always facing to the player. I have found some methods other mods use for such things, like the following code:

 

GlStateManager.rotate(-Minecraft.getMinecraft().getRenderManager().playerViewY, 0.0F, 1.0F, 0.0F);
GlStateManager.rotate(Minecraft.getMinecraft().getRenderManager().playerViewX, 1.0F, 0.0F, 0.0F);

 

It seems to work for the normal view, but if changed to third person mode with F5 (especially in the frontal view), things get quite wrong (the texture is facing not at all to the camera).

 

I suspect the actual camera/eye position is different than the player position (which seems to be the content of playerViewX and playerViewY). Is there a way to get the actual camera position (and possible the vector of the direction) instead of the player position only?

So far i found out that ActiveRenderInfo seems to contain the camera information.

 

And rotationX, rotationXZ, rotationZ, rotationYZ and rotationXY seem to contain the camera orientation.

 

Also Particle.renderParticle seems to do something similar to what I want.

 

 

But I just can't figure out why the orientation is encoded in these five rotations (or if it is the orientation actually).
