How to do naked-eye 3d?

How to do naked-eye 3d: 1. Drag the original animation into photoshop to open it.

2. Create a new blank layer.

3. Choose a good position in the blank layer, draw two reference lines with a brush, and then copy this layer, the number should be the same as the number of moving pictures and correspond to each other.

4. One-to-one correspondence between the layers with reference lines and the picture layers. Note: The number of frames must correspond to the visible layer, so as not to be confused.

5. Process the reference line layer frame by frame. If there is a reference line blocking the moving object, please erase the extra line.

6. After processing, check the reference lines corresponding to all frames, and then operate the file->; Export->; Save in the format used by the Web, just select the save location and save.

Naked 3D (English: Autostereoscopy) is a general term for the technology of realizing stereoscopic vision effect without using external tools such as polarized glasses. The representatives of this kind of technology mainly include grating technology and cylindrical lens technology.

Function:

The naked-eye 3D vision training system can effectively restore the binocular stereopsis function of amblyopic children, and can obviously improve the vision of school-age children with mild myopia. The younger the child, the smaller the degree of myopia, and the better the effect of improving vision after training.

Mainstream technical means:

The mainstream naked-eye 3D technologies include slit liquid crystal grating, cylindrical lens, pointing light source and active backlight.

1, slit liquid crystal grating. The principle of this technology is that after adding a slit grating in front of the screen, when the image that should be seen by the left eye is displayed on the LCD screen, opaque stripes will block the right eye; Similarly, when the image that should be seen by the right eye is displayed on the LCD screen, the opaque stripes will block the left eye, and the viewer can see the 3D image by separating the visual images of the left eye and the right eye.

2. Cylindrical lens. The principle of this technology is to project the pixels corresponding to the left and right eyes to the left and right eyes respectively through the refraction principle of the lens to realize image separation. Compared with slit grating technology, the biggest advantage is that the lens will not block the light, so the brightness has been greatly improved.

3. Aiming at the light source is simply to accurately control two sets of screens to project images to the left and right eyes respectively.
