1. Warping o COM amp Warpalizer tutorial How to set up your visuals to perfection using the 3D view setup Revision 1 1 Copyright Author Ivar Hestnes www univisual se What is the point with the 3D setup function Most simulations on the market today is 3D visualisations of the simulation you are running But our monitors projectors will show this as an physical 2D image on your screen monitor When you are warping your image on a curved screen using a regular checkerboard 2D warping the warping does not correct for the radius of a curved screen even if your checkerboard is perfectly aligned This will result in image distortion on screens with a large FOV Specially noticeable on your sideviews as your runway horizon can be noticed as slightly curved The greater the field of view the worse the distortion will appear The 3D setup is a calibration tool that calculates exactly how your View should be based on your physical screen measurements This is done by entering the Vertical and horisontal screen degrees into the warpalizer 2D warping is best suitable for flat screens and screens with very small curvature For example a home theatre or a control room installation 3D warping is best suitable for visuals with a larger curvature Single curved screens double curved screens and domes Copyright Author Ivar Hestnes www univisual se Notice The 3D setup is an advanced feature that req2. 77cm Proceed with the following calculation to find the correct angle Total overlap 77cm 38 5cm per overlap 2 overlap sections Total FOV 738cm 38 5cm per overlap 699 5 cm 699 5cm 233 2cm per channel 3 channels 233 2cm per channel 4 1cm per degree of a circle This means that your FSX windows must be angled to 56 9 degrees Copyright Author Ivar Hestnes www univisual se 6 Colour calibration The colour calibration is important to achieve a best possible result from the edge blending so do this as good as you can Start your DirectXtest application and hit Setup version 1 6 7 no dongle x l Prev Nm of channels 3 7_ Next F2 You will see the menu with the controls channei1 Channel2 Channel 3 for colour calibration Use the colour sliders to adjust the RGB colours Use the projector with the lowest brightness as your visual Connect sliders colour template Try to make all three as Overlap 1 Overlap 2 identical as possible Use the connect Test image 0 A WV Edit Calib 7 Sliders to move all sliders for one channel ey ome at the same time Check the square box next to Test image and use the arrows to swap between different images for colour calibration When you are satisfied with the colours click the Save button Copyright Author Ivar Hestnes www univisual se Quick setup will recommend to use the quick setup to set the points for edge

4. blending in an easy way This is not really necessary as the basic blending points is present anyway but it will save you some blending work at a later stage if you are accurate when you set the points Click on the Calib button on the warpalizer menu and select if you are using single curved or double curved screen Set the points as described on the picture When you are done with the first channel you will automatically be transferred to the next Number 3 4 and 7 8 on the first channel set the overlap and blend points for the first projector overlap The same with 1 2 and 6 7 on the center channel Set the control points horisontally A laser is recommended to make sure all the points will be level Please have a look at the picture on the next page for a more visual explanation of how to set the control points Hopefully you have a much bigger overlap than on my reference picture Copyright Author Ivar Hestnes www univisual se 7 6 8 7 When you are done with all your control points the settings will be saved automatically and we are ready to start with the next step We have now defined both the blend area and the overlap zone But we only want to keep the blend area so open the F2 menu again and pull both overlap sliders all the way to the left Then save Setup version 1 6 7 no dongle 3 Prev Num of channels 3 7_ Next Channel 1 Channel 2 Channel 3 l y VA Connect sliders Overlap Over

7. olour graphs by clicking on the X and press F2 to save your setup Same procedure for the right edge blend Dont forget to save your setup Copyright Author Ivar Hestnes www univisual se Notice regarding view settings It is very important that the view settings in your applications is set identically in the application you are running and in the 3D setup configuration on the Adv menu The 3D warping will not be correct if this is ignored Zoom setting There is a difference between a professional simulation application and a entertainment application such as FSX Most professional applications do not have need a zoom setting FSX users do need to adjust the zoom setting for each view so they are identical on all views There is no recipe for calculating this at the moment so trial and error is the solution More about FSX zoom and view settings in the Visual tutorial that can be downloaded from www ivarhestnes com FSX window borders When using the 3D setup feature these borders will normally not be visible as they are hidden in the blending If for some reason you get these borders visible please refer to the Warpalizer user manual Copyright Author Ivar Hestnes www univisual se Advanced edge blending This is neccessary if you have any bright areas in the blendzone areas in the blend zone that does not look good or if you skipped the quick setup Copyright Author Ivar Hestnes www univisual se
8. ple here is with a screen that has a radius of 235cm Use a measuring tape to measure the total horisontal view area by following the curvature of the screen measured 738cm on my screen The outline of our screen is calculated with PI x Diameter 3 14 x 4 70 which result in a outline of 1476cm on my screen First we want to find the measure per degree of a circle using the following formula Outline 1476cm circle 360 degrees 4 1 cm per degree To find our actual FOV use the following formula Measured screen distance 738cm Screen per degree 4 1cm correct FOV 180 degrees Then we simply divide the total FOV into our number of channels Total FOV 180 degrees Channels 3 Copyright Author Ivar Hestnes www univisual se Now we want to find our vertical FOV Since our projectors have a 16 10 aspect ration and we have three of them our true screen format is 48 10 16x3 48 Then calculate the Vertical FOV by using this formula Horisontal FOV 180 degrees Horisontal aspect ratio 48 Multiplier 3 75 Multiplier 3 75 X Vertical aspect ratio 10 Vertical FOV 37 5 degrees Next step is to find how much view angle to apply for each channel and for our FSX views First you need to measure the actual overlap on your screen Follow the curvature On my screen the overlap between the left and center channel is 37cm And my overlap between the center and right channel is 40cm This give a total overlap width of
