Moving from OpenGL Fixed Functions

pmvMatrix

com.jogamp.opengl.util.PMVMatrix

pmvMatrix can make a matrix by using glTranslate/glRotate etc. FFP instructions. Example: 

   pmvMatrix.glMatrixMode(GLMatrixFunc.GL_PROJECTION);
   pmvMatrix.glLoadIdentity();
   pmvMatrix.gluPerspective(fov, aspect, zNear, zFar);
   pmvMatrix.glMatrixMode(GLMatrixFunc.GL_MODELVIEW);
   pmvMatrix.glLoadIdentity();
   pmvMatrix.glRotatef(360 - pitch, 1, 0, 0);
   pmvMatrix.glRotatef(360 - yaw, 0, 1, 0);
   pmvMatrix.glRotatef(360 - roll, 0, 0, 1);
   pmvMatrix.glTranslatef(-position.x, -position.y, -position.z);
   pmvMatrix.update();
