Mesh rotate()

Hi there i need a bit of help :)

I have a mesh of an aeroplane, and i am using the rotate() command to rotate the mesh. However the rotate axis's are fixed in relationship to the screen.This causes the model to perform unusual rotations when more then one axis is being used. Is there a way to change this so they stay in relationship to the model?

I hope i have explained my self correctly

In general, we use translate() along with rotate() to put the rotation axis where we want.

Thanks for the reply.

I don't think this will solve my problem ( i am probably not explaining myself correctly)

When i do a rotate along the x and y axis, the model roation axis flips direction when pointing away from the screen compared to when it is pointing towards the screen .

Here is a small bit of my code

lights();

pushMatrix();

translate(width/2, height/2, 0);

rotateX(PI * longRot);

rotateY(PI * latRot);

rotateZ(PI * normRot);

model.draw();

popMatrix();
