Perspective-Correct Normal for Equal Angle Interpolation

By applying the result of perspective correction for bilinear interpolation to equal angle interpolation and using geometric relations of line segments, a correct equation of equal angle interpolation is obtained. Moreover, the corrected normal vector obtained from our correct equation still being a...

Zusammenfassung:By applying the result of perspective correction for bilinear interpolation to equal angle interpolation and using geometric relations of line segments, a correct equation of equal angle interpolation is obtained. Moreover, the corrected normal vector obtained from our correct equation still being a unit normal vector is proved by using the method of vector algebra; Experiment results show that the vision difference between having and not having perspective correction of equal angle interpolation could be noticed clearly
