The principle of raster painting, how to make a three dimensional raster painting

Principles of optical refractive imaging and visual disparity of the eyes.

Raster painting, also known as "three-dimensional painting" and "panoramic painting", three-dimensional painting is a special picture that can directly see the three-dimensional effect, which is designed by using the principle of optical refraction imaging and the parallax difference of the eyes

The principle of rasterization is a very good principle, and this principle of coronation is a process of being able to look at the principle of his painting by the way of uh resistor, so it is very good-looking.

The principle of drawing this picture means that when you are familiar with the picture, and then you go to the process of painting, you will be able to image it.

The principle of light side There are many principles of light side, and he has learned. Students studying science will definitely understand his reasons at a glance.

The biochemical principle is based on what the words and the sketching program is.

It's still very complicated, and a lot of it is very, very professional and detailed.

Speaking of his principle is still very close, and we all like it very much, and it must not necessarily contribute to our love.

There is a principle, what is this origin cut here? If you look at Du Fu's ability to get here, you will grow up.

I also know about this, if you want to know, you can go to the browser and look for it, you can find this in all cases.

The principle and production of raster painting.

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

The special picture is designed by using the principle of optical refraction imaging and the parallax 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 into a special image of residual excitation according to a certain rule, and the grating can separate the parallax image, and the two are bonded and assembled to form a picture.

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

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.

Now Zhengzhou Huaying digital image output introduces foreign advanced technology to produce three-dimensional three-dimensional map advertising and installation.

Decorative paintings. and answer the incoming call question. Technical training.

Grating is usually used to form step patterns with different heights and widths on the silicon wafer, so as to produce optical effects such as interference, diffraction, and reflection against the light emitted on it, so as to achieve certain optical functions. The conventional grating manufacturing process is to grow a certain thickness of dielectric layer on a silicon wafer, and then go through multiple photolithography and etching to form these step patterns.

a first photoresist and a second photoresist are successively formed on the substrate surface, wherein the second photoresist covers the first photoresist and its minimum apparent energy is less than that of the first photoresist; the first mask plate is used to carry out the first ** treatment on the second photoresist, wherein the second photoresist forms a first photoresist pattern in the first mask area; a second mask is used to carry out a second ** treatment on the second photoresist, wherein the second mask plate at least partially covers the first ** area, and the first photoresist forms a second photoresist pattern in the second ** region; the first photoresist and the second photoresist are developed to form a photoresist step structure with a first photoresist pattern and a second photoresist pattern.

The gate measurement system consists of a grating ruler and a grating digital display. The encoder transmits the collected displacement signal to the encoder digital display to display the measurement results. The displacement signal of the grating ruler is converted into a sine wave signal by the photodiode, and then converted into a square wave signal that can be recognized by a single-chip microcomputer through the subdivision circuit and the shaping circuit.

According to the working principle, gratings can be divided into metering gratings and physical gratings. The metering grating is precisely measured and controlled by the Moiré fringe phenomenon of the grating, and the metering grating is generally relatively thick; Physical gratings are mainly used as scattering elements for the determination of optical wavelength and spectral analysis. A grating ruler is a type of metering grating.

The grating sensor is mainly composed of light source, illumination system, main grating, indication grating, receiving optical system, and photoelectric connection.

Components, etc.

Safety light curtains are used for area protection, such as dangerous areas to prevent people or human fingers from entering, at which time safety light curtains can be installed. There is a self-test function inside the safety light grid, and when the safety light barrier fails, the normally closed output of the safety light grid becomes normally open. When a safety light barrier obscures any one or more light spots, only one switching signal is output.

Mott intelligent measurement grating is used for measurement, there is no self-test function, each optical point corresponds to 1 output, and the output of the measurement grating is a 10-base data packet after signal integration.
