animation experiment: <\/strong><\/p>\n

Based on the work of Robin Roades<\/a>, make an animation with still images. \u00c2\u00a0If you can, cross fade between them. \u00c2\u00a0Can you tell a story with just a few frames? \u00c2\u00a0Think especially of using people and or mixing scales. \u00c2\u00a0 Don’t doctor the images, and keep the camera stationary.<\/p>\n

code: <\/strong><\/p>\n

a) fastest non moving speed
\n<\/strong>
\nfind the fastest speed for the square to move across the screen and have the motion be imperceptible. Time how long it takes for the square to move across the screen and measure the physical (not pixel) distance. What is this speed in inches\/second ? for kicks, What is it in in mph?<\/p>\n

b) fastest still\u00c2\u00a0perceptible\u00c2\u00a0speed<\/strong><\/p>\n

find the fastest speed for the square to move across the screen and have the motion be still perceived as continuous (not discrete jumps). Time how long it takes for the square to move across the screen and measure the physical (not pixel) distance. What is this speed in inches\/second ? What is this rate in mph?<\/p>\n

c) click to change pta and ptb
\n<\/strong>
\nmake an application where whenever you click, you change either the ptA position or the ptB position to the mouse position, alternating every time you click.<\/p>\n

d) shaper controlls something else besides position<\/strong><\/p>\n

Make the shape code control another property of the object, such as its size or color. \u00c2\u00a0Make the nicest composition that you can. \u00c2\u00a0Try to make it elegant and organic.<\/p>\n

(for the xeno code)<\/p>\n

e) multiple xenos<\/strong><\/p>\n

make a series of xeno objects which follow the mouse, each at different rates. give them slightly different colors so that you can perceive them as independent objects. \u00c2\u00a0\u00c2\u00a0you will have to modify the rectangle object so that they can have unique colors.<\/p>\n

+<\/p>\n

bonus homeworks <\/strong><\/p>\n

f) multiple xenos trail<\/strong><\/p>\n

<\/strong>If you are really feeling like showing off, make an array of xeno objects where the first element follows the mouse, the second element follows the first, the third follows the second, etc.<\/p>\n

g) shapers via penner<\/strong><\/p>\n

in class, we used powf to shape a linear signal. \u00c2\u00a0there are more advanced ways to do this (for easing and out, and for snap to, etc). \u00c2\u00a0Some of these have been collected by robert penner as \u00e2\u20ac\u0153easing equations\u00e2\u20ac\u009d<\/a>. \u00c2\u00a0some folks have ported this from AS to c++, you can find them\u00c2\u00a0here<\/a> &\u00c2\u00a0here<\/a><\/p>\n

try to hook them up and make a compelling composition with linear and nonlinear animating elements.<\/p>\n","protected":false},"excerpt":{"rendered":"
