Our matrix-fu has really gotten us places. Let's go further.
I want to move the triangle out of the way. We'll do this by setting up another transformation matrix and then using it on the model when it's time to draw.
Add two new matrices named
// Model variables private float triTransform; // Viewing variables private float triView;
Initialize them in
onCreate as well:
triTransform = new float; triView = new float;
Let's set the model matrix that positions the triangle in the
initializeScene method (called by
onSurfaceCreated). We'll offset it by 5 units in X and backwards 5 units in Z. Add the following code to
// Position the triangle Matrix.setIdentityM(triTransform, ...
