Hello,
As the glPushMatrix() and the glPopMatrix() functions are now deprecated in the OpenGl compatibility profile(confer OpenGL superbible 5th edition), I tried to search equivalent of:
-void GLMatrixStack::PopMatrix(void);
-void GLMatrixStack::PushMatrix(void);
of the C++ GLTOOLs library in LWJGL library, but I didn't find it in the supposed most appropriated location (ie:org.lwjgl.util.vector package).
Could you please help me know how should I do to make matrix stacks? :)
As GLTOOLS isn't part of OpenGL, it has no business being in LWJGL. You are supposed to implement your own matrix stack. LWJGL provides a Matrix4f in its util.vector package, and it's up to you to implement push and pop :)
Here's a basic implementation:
import java.util.Stack;
import org.lwjgl.util.vector.Matrix4f;
public class MatrixStack {
private Stack<Matrix4f> stack;
private Matrix4f current;
public MatrixStack() {
current = new Matrix4f();
stack = new Stack<Matrix4f>();
}
public Matrix4f getTop() {
return current;
}
public void setTop(Matrix4f m) {
current = m;
}
public void pushMatrix() {
stack.push(current);
current = new Matrix4f(current);
}
public void popMatrix() {
current = stack.pop();
}
}
Okay, thanks a lot , I'll do that! :)
