What Are the Different Uses of 3D Vision?
3D Vision is a 3D stereo display technology for NVIDIA graphics cards. NVIDIA 3D Vision is divided into 3D Vision and 3D Vision Discover technologies. After equipped with corresponding 3D glasses and other equipment, you can enjoy 3D blockbusters and play 3D games.

- 3D Vision is a 3D stereo display technology for NVIDIA graphics cards. NVIDIA 3D Vision is divided into 3D Vision and 3D Vision Discover technologies. After equipped with corresponding 3D glasses and other equipment, you can enjoy 3D blockbusters and play 3D games.
- NVIDIA 3D Vision is divided into 3D Vision and 3D Vision Discover technologies.
- 3D Vision has relatively high hardware requirements. To experience the 3D Vision effect, three conditions must be met:
- 1. Must use NVIDIA Geforce 8 or above graphics products;
- 2. Must have a monitor with a refresh rate of 120Hz;
- 3. NVIDIA's 3D Vision glasses must be purchased; 3D Vision Discover is more popular, with the following requirements:
- At present, there are four common principles of three-dimensional stereo imaging, which are color division method, light division method, time division method, and holography method. Among them, holography is still in the research stage, so there is no actual product. 3D Vision technology is realized through time division. The advantage of time division is that the imaging effect is better, but the cost is higher. 3D Vision Discover uses the imaging principle of color separation method. As long as you wear red and blue glasses, you can see the effect.
- Principle of time division method:
- NVIDIA's 3D Vision technology uses special glasses to adjust the lenses to opaque black after powering on through the LCD under ultra-high-speed conditions, to respectively shield the left and right eyes of the person, and let the two eyes see two different angles. The screen, that is, the right lens becomes black when the left eye picture is played on the screen. After switching once, the left lens becomes black when the right eye picture is played on the screen. In this way, fast switching ensures that the left and right eyes are slightly different. image. The simple understanding is that NVIDIA allows the GeForce graphics card to calculate two different pictures for each frame when calculating the game (the movie effect is realized by dual cameras), and displays them on the monitor. Different images give the human eye an illusion, making our eyes mistakenly seeing a "three-dimensional" object, thereby realizing stereo imaging technology.
- In other words, during the entire display process, the display must transmit left and right eye images at a very high frequency. At the same time, the 3D Vision glasses also switch the left and right eye LCD screens at the same high speed, so that people can see different pictures . Of course, the premise of achieving this function is that your monitor must also be able to support such a high refresh rate, so the higher the refresh rate of your monitor, the better. In general, the minimum must be above 120Hz, so that the refresh rate assigned to each eye can reach 60Hz, so that it is not too dazzling.
- Principle of color separation method:
- The color separation method is to let the audience wear red and blue colored glasses, and then use the color filter function of the red and blue glasses to separate the overlapping images, so that the brain mistakes it as seeing a stereo image. This method does not require changing the projection equipment. It can be implemented directly, and the cost is low, but it is easy to cause visual fatigue to the human eye.
- It is recommended to use WIN7 or VISTA operating system and NVIDIA GeForce 3D Vision driver.
- Take 3D Vision Discover as an example
- After the driver is installed, you can enable 3D Vision Discover in the start menu-NVIDIA Corporation-3D Vision-and then enter the 3D VISION installation wizard. (To turn off the technology, you can choose to disable 3D Vision Discover through this path.)
- After setting, you can see the 3D picture, or watch the 3D picture in the start menu-NVIDIA Corporation-3D Vision-3D Vision Preview Package 1.

- If it is impossible to watch videos with 3D VISION DISCOVER by installing only the driver, you must also use the NVIDIA Stereoscopic 3D Video Player player software to achieve it. While downloading and installing Stereoscopic 3D Video Player, you can download 3D videos from NVIDIA's official website.
- Stereoscopic 3D Video Player only supports files in some formats, but even the corresponding formats are not guaranteed to be converted to viewable 3D effects. It is best to download 3D videos from the NVIDIA official website.
- Many games currently support 3D Vision, such as Half-Life 2, Far Cry 2, and so on. You can view the list of supported games through the "View Game Compatibility" in the NVIDIA control panel.
