So, will first rotate 45 degrees about the x axis, then scale the object to (10,10,10), then translate to (1,2,3). in. The values for the vertex positions with which you draw your circles are in the order of hundreds (likely, because you want to address pixels as indicated by the values for the projection matrix). If you call translate (1,0,0) the point will be in (1,0,0), after that you call rotate (90, 0, 0, 1) and your point will be on .
