What Is Real World?
Flat plane mapping is used for desktop applications by taking an image and projecting it onto a planar surface. However, it doesn’t support viewing the image in 180 or more degrees. In actuality, viewing the image in 160 degrees begins to look stretched. This is due to the fact that once the image is wrapped around the viewer, what is now located perpendicular to the eye is not a true representation of what would be on the viewer’s side in the real world.
Traditionally, to project a true representation of an image in 180 degrees or more, a complete alternative set of mappings would need to be configured. These spherical or cylindrical mappings involved using specially crafted test patterns to align the display, multiple camera angles to capture the image, followed by masking off the areas of the projected image that spilled over. It was an entirely parallel configuration to flat plane mapping and was often a lengthy and tedious process.
SimVisuals introduces Real World Mapping™, which automatically maps a spherical or cylindrical image at the click of a button. It uses the information from flat plane mapping, along with additional software, to perform the necessary calculations so you don’t have to. As with the historic method of spherical or cylindrical mapping, Real World Mapping uses multiple cameras with different headings and merges these into a single image to create a seamless surround display.
Using Real World
Real World Mapping can be spherical or cylindrical, depending on the shape of the screen. For dome, spherical, or toroidal screen shapes, ‘Spherical’ mode is needed. For cylindrical screens, use ‘Cylindrical’ mode. Real World Mapping can be toggled using the Enable Real World Mapping checkbox on the Real World tab of the SimVisuals Web UI.
