Introduction to raster, how to make raster raster painting

Raster three-dimensional painting is the use of special optical materials (commonly known as grating materials) to display a lifelike three-dimensional world on a flat surface, an incredible three-dimensional effect. The hand is flat to the touch, and the eye looks three-dimensional, with a prominent foreground and a deep background, and the scenery is realistic. All types of images can be made with three-dimensional effects.

It is a combination of digital technology and traditional printing output technology, with a set of sequences of three-dimensional images to form a **, ** surface covered with a layer of grating. Through different processing and material selection, raster painting can also make the effects of two changes, three changes, rotation, scaling, rainbow and other effects mentioned on the Internet, which are actually extensions of the principle of raster imaging. Due to the high cost of raster stereoliths, any lenticular stereoliths that are well stocked are very important.

The principle and production of the raster painting troupe.

Raster painting, also known as "three-dimensional painting" and "panorama painting", three-dimensional painting is a three-dimensional effect that can be seen directly by Minsun.

The special picture is designed by using the principle of optical refraction imaging and the visual difference of the eyes, and is designed by computer simulation.

An art drawing made of optical medium with a three-dimensional dynamic effect. People's eyes are 6-7 cm apart.

The left and right eyes look at objects from two slightly different angles, and the brain compares the two.

Images with parallax are composited to create a three-dimensional feeling. When watching a stereoscopic movie, the audience is required to wear a special pair of eyes.

The function of the glasses is to make the parallax images taken by the two cameras enter separately.

The left and right eyes of a person. Raster-stereo painting, like stereoscopic film, only uses lenticular instead of spectacle lenses, eliminating the need for the audience.

The burden of wearing glasses.

The raster stereoscopic painting is mainly composed of two parts: the raster and the sampling map, and the sampling map is composed of more than two parallaxes.

The image is synthesized according to a certain rule of the special image, the grating can separate the parallax image, and the two are bonded and assembled to form one.

Three-dimensional painting, when people observe this kind of **, they can directly see a three-dimensional three-dimensional picture and painting in a plane.

Things can be presented vividly and vividly like real scenes, and even animations appear, giving people a strong visual impact. It allows the eye to see the up, down, left and right sides of an object.

Three-dimensional relationship between front and back. It is a three-dimensional painting in the true visual sense.

Stereo grating, also known as dot grating, also known as dot grating, holographic grating, array grating, microconvex lens array grating, etc.

The grating is composed of an infinite array of dots, each of which is relatively independent, and the missing dot is a miniature convex magnifying glass.

The 3D stereoscopic painting that facilitates the production of this kind of raster can be 360 degrees**, and the picture can be rotated in any direction, up, down, left and right.

The 3D three-dimensional painting made with the dot grating has two effects: the 3D effect of the realistic pattern Pei Zheng: it is a real pattern, with thickness and continuity.

Generally, it is shot with a matrix stereo camera, such as a 3x x x5 and other arranged stereo cameras, and it can also be artificially simulated with professional stereo technology.

The 3D effect of regular graphic production: generally there are several levels, the foreground and background are regular graphics with a sense of depth of field, and the middle layer is an advertising screen, promotional pattern or text without three-dimensional effect.

Raster stereoscopic painting is the use of 3D printing technology to layer the picture through computer processing, printed on photo paper or printed on specific paper, through the combination of the most early and discreet grating material to present a delicate three-dimensional sense, the use of convex lens refraction to produce image segments, so that the eyes accept different image information, Lu Fujing produced a three-dimensional sense.

It is a naked-eye 3D three-dimensional painting in the true sense.

1. Adjust the image.

1. Open a layered image of the design.

2. "Image" menu - image size, resolution set to pixel centimeters, width and height are set by yourself.

Second, the grating layer production.

1. Create a new layer, hide other layers, and adjust the image to the maximum through the navigator.

2. Select the single-column marquee tool and click on the canvas. Select the Pencil tool (place the pencil tool tip in pixels) and click on the selection.

3. Press Ctrlatt and tap the right arrow key 7 times, release the Ctrlatt key and click the right arrow key again.

4. Select the Rectangular Marquee tool and select 7 black and 1 transparent rectangular area with a width of 8 pixels. Select the definition pattern from the menu and click OK.

5. Clear the current layer: Select All - Delete - Deselect (Ctrld).

3. Get 8 similar images.

1. Select a layer that needs to be three-dimensional (other layers other than the middle ground).

2. Make a copy (Ctrlj), select the Orange Gesture Tool, and press the left arrow key to move 10 times (refer to the number of moves table for specific moves).

3. Copy, re-move (the same number of moves), cycle operation, copy and move a total of 7 images (copy 7, add the original one, a total of 8 images).

4. Divide and arrange images.

1. Select the original layer, hide other layers, load the raster layer selection (press Ctrl to click the raster layer), and select the rectangular marquee tool.

2. Press the delete button to delete, press the left arrow key once, and select the previous layer.

3. Continue to delete, cycle through until you have finished splitting the other copied layers, and then deselect (Ctrld).

5. Flattening Images: Merge visible layers (Ctrlshifte).

Sixth, at this point, the three-dimensional operator of a layer is absolutely complete. For other layers that need to be three-dimensional, follow the steps above. It's just that the number of moves is not the same as the direction.

7. After all the layers are made, delete the raster layer.
