The original screen panel period.
(4) matched FBG and frame number, such as the second grating match the second frame.Close other figure layers, leave behind the first grating and
First frame chooses the first grating figure layer at this time.Blank is selected with magic wand menu, and selects selection reversed, establishes the constituency of grating.
Then the figure layer for choosing first frame clicks delete and deletes pattern in constituency.
(5) residue frame is handled with same method, and closes all gratings, open all frames, Flatten Image printing
Grating egative film required for obtaining.
(6) resulting preposition grating and postposition animation pattern are exported as into png format, is printed to by the size requirement of device
On KT plate.
Moire fringe is demonstrated using above-mentioned Moire fringe grid.
The KT plate of above-mentioned printing is inserted into device between longitudinal rail.By hand third pulley, second is driven to slide
Wheel is rotated with first pulley, to keep original screen panel mobile.With the movement of original screen panel, when Chong Die with raster back color picture, change can go out
Now dynamic animation effect realizes the demonstration of Moire fringe phenomenon.
More specific embodiment is as follows: the production program of Moire fringe grid
1, the production of original screen panel: design width of fringe is 0.5mm, and spacing is the grating of 0.1mm, and is printed on transparent sub- gram
On power plate, acrylic board is having a size of length × width x thickness=60cm × 40cm × 5mm.
2, the production that raster back color is drawn:
(1) the GIF format dynamic picture of 6 frame of computer manufacture is utilized.
(2) by above-mentioned GIF format cardon, import Photoshop software, setting dimension of picture for length × wide=60cm ×
50cm。
(3) above-mentioned grating is produced using PS, and copies six grating bottoms, each successively moved right than previous
0.1mm。
(4) matched FBG and frame number, such as the second grating match the second frame.Close other figure layers, leave behind the first grating and
First frame chooses the first grating figure layer at this time.Blank is selected with magic wand menu, and selects selection reversed, establishes the constituency of grating.
Then the figure layer for choosing first frame clicks delete and deletes pattern in constituency.
(5) residue frame is handled with same method, and closes all gratings, open all frames, Flatten Image printing
Grating egative film required for obtaining.
(6) resulting preposition grating and postposition animation pattern are exported as into png format, prints to KT by 1:1 size requirement
On plate.
