A bounding box-based method for reducing the number of samples tested for rendering a screen space region of an image includes determining a trajectory of a primitive in screen space for an image which is to be rendered and constructing an axis-aligned bounding box for the screen space region. The axis-aligned bounding box includes a bound in a non-screen dimension that is defined as a function of the screen space trajectory of the primitive, and overlaps a portion of the screen space region. One or more sample points which are located within the screen space region, and which are not overlapped by the axis-aligned bounding box are excluded from testing.
