3D Fireworks Glasses - Feel the Joy of 3D Firework Displays

There are four principal forms of 3D being used to-day. Stereoscopic, Pulfrich, Chromadepth, and TV Eyes 3D. Each uses a different type of glasses, and a different facet of view, to create 3D images. Stereoscopic 3D, also known as binocular 3D, is the type many people think of when they think 3D. Stereoscopic 3D is created by filming a scene from two sides and combining the opinions into a single three-dimensional picture. It's this sort of 3D that is employed by 3DTVs and movie theaters. Stereoscopic 3D glasses were created so that only one position of the image is open to each eye, this is done with different colored lenses, just like the red/blue (also known as anaglyph) glasses, by polarized double diffraction glasses, such as those used in Real D theaters, and by shutter glasses such as those used in some 3D theaters and 3DTVs. The restriction of this kind of 3D is that the film itself must be offered in 3D structure, having a separate picture for every eye. This is achieved by shooting the movie in 3D, or get electronically changing it into 3D format. The power is the fact that this type of 3D provides very three-dimensional picture, detailed with 'jump out' effects. Pulfrich 3D can be a kind of pseudo-stereopsis which uses a period delay between eyes to trigger each eye to view a slightly different picture as the video plays across the screen. Pulfrich 3D glasses have one clear lens and one dark lens. The image seen through the lens arrives in the mind a fraction later compared to image from the clear lens, producing a form of stereoscopic vision. The benefit of this sort of 3D is that it can be shot with normal cameras without needing to develop a secondary image in the video itself. The drawback is that in order for the 3D effect to work -- motion within the scenes must advance in the same course constantly. However images or movement in other instructions do not create a 3D effect. ChromaDepth 3D is a kind of 3D that relies upon the different wavelengths of different colors. Red having a longer wavelength and blue faster, making blue appear farther away than red, natural farther away than red and so forth. By using prisms the different shades are translated by your brain to be at different distances, according to the visible wavelength of this color. The bonus is that text and three dimensional pictures can be produced by just mixing reverse shades. The drawback is having a prism over each eye and that pictures have to be particularly created to incorporate the appropriate color combinations. TV Eyes 3D can be a form of 3D that uses 'level of field,' a concentrating impact created by a camera aperture. A camera aperture, the small hole behind the lens of the camera, determines the number of length of which things come in focus. This is often seen as the effect that certain thing will be in sharp focus while some in the front or behind it are confused. Altering the focus of those 'depth of field' tips through another aperture, and offsetting the angle, causes the brain to understand the modifications of sharpness and blur as different miles, making the picture look three dimensional. The issue with this type of 3D is the glasses possess a line of small holes to look through. And that the place of the openings must be adjusted for every individual consumers eyes. The bonus that it could create 3D from TVs. and typical 2D movies More details is found here. All 3D glasses, regardless of what kind, have their drawbacks -- the various shades of anaglyph red/blue glasses, the dark and light lenses of Pulfrich, the prisms of ChromaDepth, the openings of TV best diffraction glasses, or the technology and shuttering motion of shutter glasses, must all be modified to in order to appreciate 3D movies.
