I can't seem to figure out the pattern of ortho size in relation to desired height though. Now, setup input configurations including projector model type, model name, lens, aspect ratio, and projected image size. Some written examples of aspect ratio size differences, and the effect on the projection:Īspect ratio 1 and ortho size 2: 4x4 areaĪspect ratio 2 and ortho size 2: 8x4 areaĪspect ratio 2 and ortho size 1.5: 6x3 areaĪspect ratio 1.5 and ortho size 1: 3x2 areaĪspect ratio 0.25 and ortho size 4: 2x8 area As such, it is not as simple as just calculating aspect ratio for the width, and setting orthographic size as the height. However, orthographic size expands in all directions. how do I convert 5x7 into aspect ratio AND orthographic size such that a 5x7 grid area is shown as selected.Īspect ratio is easy just width / height.
PROJECTION ASPECT RATIO CALCULATOR HOW TO
It looks nice, but I am confused by how to adjust the width/height (or depth, depending on how you look at it).Īdjusting the aspect ratio, and the orthographic size gives me what I need to map the selection area to a width/height, but I do not know how to do the conversion.įor instance, lets say the player selects a 5x7 area on the play grid (all grid points are a size of 1).

For additional help in selecting materials, or projector screens in general, feel free to give us a call. (7 2 and 7 2.4 14-16.8) Example 2: Maybe you don’t know which screen size want, but you do. Well use our custom Viewing Distance Calculator. To do this, I have added a game object with an orthographic projector to my scene. If the screen width is 7 feet and the projector’s throw ratio is 2.0 2.4:1 (because projectors have zoom lenses, they also have a range of throw ratios) then you can place your projector anywhere from 14 to 16.8 feet away from the screen. 16 / 9 1.78 (rounded) If you know your projector screens diagonal size: Projector. Tip: Check out Epsons web-based distance calculator. With this calculator you can quickly and easily calculate any type of aspect ratio, saving time and effort If you need to change the size of an image to a specific aspect ratio, this tool will help you a lot. screen size, aspect ratio, shift range and floor or ceiling installation. Simply put, a 16:9 projection screen is 1.78 times as wide as it is high. Keep in mind your environment setup, any installation limitations, and your potential projected image size. Aspect ratio calculator, calculate the sizes of your photos or videos, for example 16:9 aspect ratio.
