Remark for Perspective projection - Transformation
A Perspective projection can have at most three Principle Vanishing points and at any rate one Principle vanishing point. To know the consequences of a perspective transformation, identify the figure.
The figure demonstrates the perspective transformation on z=0 plane of a specified line AB that is parallel to the z-axis. The A*B* is the projected line of the specified line AB in the z=0 plane. Assume here that a centre of projection be at (0,0,-d) on the z-axis. The Figure (A) demonstrates that the line A'B' intersects the z=0 plane at the similar point as the line AB. This also intersects the z-axis at z=+d. This means the perspective transformation has transformed the intersection point.
What is the use of Projection reference point? In Perspective projection, the object positions are transformed to the view plane with these converged projection line and the p
