In ordinary plane painting, the picture will not shake. Three-dimensional painting is not good, and there are two biggest problems-shaking and fault. Most people don't understand, how can the painting still shake? Jitter is caused by afterimage. Cubic painting is not a painting, but a superposition of several paintings. The human eye sees the same picture with different depth of field, resulting in stereo. Under the refraction of grating, multiple images will produce ghost at a certain angle, and this ghost will keep a certain angle range. People will feel dizzy when standing at this angle. This ghost is also called ghosting. In the viewing angle range of 90 degrees, the afterimage will appear as many as 4 to 12 times depending on the grating material. Frequent ghosting appears, as if the picture is shaking.
The primary problem of three-dimensional painting is not to enhance the three-dimensional sense, but to eliminate the residual image and jitter. It is impossible to say that it is completely eliminated, but we can only try our best to narrow the angle of the afterimage and reduce the jitter amplitude. If the drawing technique is not too hard, it will increase the afterimage and jitter, and the picture will look unsightly. Conventional training institutions and most stereoscopic painting production companies can't reduce this sloshing. This is also one of the fundamental reasons why many people who study acoustics finally give up.
Fault is another thorny problem in three-dimensional painting. Fault is a fracture between three-dimensional planes, and several obvious cracks are exposed in the picture. Most training institutions and most stereoscopic painting production companies can't solve this problem. This is another reason why many people who study acoustics finally give up. After a long and arduous practice and exploration, Shenzhen Company Audio has completely eliminated this problem. The application of interlayer optimization technology and real-life approximation technology makes the picture smooth transition and seamless connection no matter how far the depth of field is, how many objects and how complicated the picture is. Really reproduce the real scene.
In addition to the above two aspects, the conception of the whole picture is the third difficulty. I just started to learn to do three-dimensional, and I often don't know where to start when facing the picture. After long-term practice, the ability to judge the picture will be greatly improved and the drawing speed will be much faster. What makes the depth company different is that the picture conception and hierarchical division follow the law of depth data simulation. This method can accurately control the real displacement of each point and layer on the picture, and then accurately control the three-dimensional strength of the picture.
The last difficulty is the fast and accurate judgment of raster data. Many experienced people in the stereoscopic industry can't come up with a good way to accurately judge raster data, and print a bunch of raster bars invariably. With the increase of grating types, the format of grating becomes larger and larger. The larger the raster format, the worse the data stability. To make a hundred paintings, you have to measure them a hundred times. If you are not sure, you have to measure them several hundred times. Through a large number of tests on various gratings in China, you have summed up a set of unique testing techniques, which can accurately obtain grating data only by measuring for three times.
