New stereoscopic display mode
We have just added a new stereoscopic display mode in Digi3D.NET that will allow you to work with 3D monitors or TVs that implement the Side-by-Side mode 3D. This mode does not require having a stereoscopic graphics card (i.e., of the Quadro family) and is useful to be able to view stereoscopic with a laptop computer. Basically, when activating the mode on the monitor, it expands the left half of the monitor over its entire surface and shows it to the left eye and immediately after expands the right part of the monitor over its entire surface and shows it to the right eye and so on. You can get the idea with the image that heads this blog post. As the monitor expands horizontally the images pixels are displayed twice as wide as high, so to avoid this distortion, Digi3D.NET displays pixels twice as high as wide, so that when the monitor expands in width the aspect ratio of the pixels is correct. Below I show you a screenshot of a model with a large Zoom and with the bilinear interpolation option disabled so you can see how the pixels are displayed in this mode without activating stereoscopic on the monitor: No You can see that the pixels are twice as high as they are wide. A problem that has this is that the monitor performs the operation with the whole screen, so if you have visible the Windows taskbar, it will also expand (you will see the left half with the left eye and the right part with the right eye), and the toolbars and menu bar of Digi3D.NET, so my recommendation is that if you have no choice but to view stereoscopic with a computer that does not have a Quadro graphics card and the only option is to use a monitor like this, that you maximize the photogrammetric window by pressing the combination of keys Ctrl + Alt + Enter in Digi3D.NET. So now the program supports the following stereoscopic modes:
| Mode | Requires Quadro card | Monitor or TV type | Use |
|---|---|---|---|
| Controlled by driver | Yes | Monitor compatible with NVidia 3D Vision | Professional |
| Stereoscope | No | On any monitor | Professional |
| 3D | No | Monitor or TV 3D that implements this stereoscopic mode. | To make a demonstration and little more. The whole monitor is shown in stereo and in the parts that there is no image are shown parts of windows that can confuse or dizziness |
| 3D-Side-by-side | No | A 3D monitor or television that supports this stereoscopic mode. | Suitable for a demonstration and little else. The entire monitor is displayed in stereo, and areas without an image show parts of windows that can be confusing or cause dizziness |
| Horizontal interlacing | No | 3D Passive Monitors | It could be used for professional use but I personally would not. This system has the problem that with the left eye even lines of the monitor appear black and with the right eye odd lines. The texts appear as cut with this system. |
| Vertical interlacing | No | Auto-stereoscopic monitors | It could be used for professional use but I personally would not. This system has the problem that with the left eye even columns of the monitor look black and with the right eye odd columns. The texts appear as cut with this system. |
| Anaglyph | No | On any monitor | To make a demonstration and little more.Having color filters in the eyes for a long time can cause visual fatigue |
