Interactive Animation and complementary Animation

These two words are the inevitable result of the development of flash to today. In our concept, animation is a piece of film that can be enjoyed by others. Today, we can use the scripting language of flash to write for people to use.Program. Supplementary Animation: a film made for people to enjoy. Interactive Animation: Uses Flash technology to make programs available to people. Radians and angle conversion: Radian (radians) = angle (degrees) × math. PI/180 Angle (degrees) = radians (radians) × 180/Math. Pi In animation production, the corners we use must be converted to radians before calculation. Otherwise, the wrong answer will be calculated. The sine and Cosine values are used to give an angle and calculate a proportional value, that is, the ratio of the opposite side, adjacent side, and oblique side. The arcsin and arccosine give a proportional value to calculate the angle. Tangent value: returns the angle to calculate the ratio of the edge to the adjacent edge. Arc tangent value: returns the ratio of the Peer edge to the adjacent edge, and calculates the angle value.
