What is DOT3 lighting?

http://stackoverflow.com/questions/1894351/what-is-dot3-lighting

if this will be a net win as usual the advice is to try and see. Finally the diffuse lighting intensity in a point is proportional to the cosine of the angle between the surface normal and the direction of the light. For two vector the dot product is..

http://stackoverflow.com/questions/6759028/using-uipinchgesturerecognizer-to-scale-uiviews-in-single-direction

share improve this question If I understand correctly your question you are aiming at having non proportional scaling along the horizontal and vertical axis. In this case the thing comes down to providing your affine transform piece.transform.. the scale factor delta is 1 gestureRecognizer.scale the delta is the multiplied by a factor so that it is somehow proportional to the displacement along the horizontal or vertical axis when the displacement is zero the delta scale is also zero when..
