![]() You can undo changes after validation using the history.Ĭlick this button to ignore the changes and return to the previous state. The preview of the panorama then adjusts according to the constraints you have to define. The panorama’s central point is indicated by the intersection of the two grey lines of the grid, one is horizontal and the other is vertical.Ĭlick on this button to confirm the modifications or push the enter button. Rotation around a central point (clockwise for a positive value). Vertical shift (towards the bottom for a positive value). Horizontal shift (towards the right for a positive value). The angle of rotation must be expressed in degrees the successive changes are added to each other (a rotation of -10° is cancelled when it follows a 10° rotation). This tool lets you make changes to the panorama with the 90° right rotation, 90° left rotation, positioning of the viewpoint, Automatic Level and vertical lines tools. Therefore, we strongly advise you to click on the Auto Level tool after rotation Note that even if the panorama seems too aligned, rotating it 90 degrees can cause a misalignment in the pictures. These buttons let you switch a panorama when the corresponding group pictures do not have a good landscape/portrait orientation. ROTATION 90° rotation to the left or right When the vertical viewing angle is large, the stretching effect at the top of the image (near the zenith) and at the bottom of the image (near the nadir) varies from unusual to very unusual. Spherical or equirectangular projection Advantages:Īuthorizes the assembly of all panoramas.įor the direct display (without a viewer) of a panorama on the screen and for feel we need to ensure that the curvature of parallel straight lines on the horizon is still acceptable (there is no rule, you need to be the judge). The vertical angle is limited, it is imperative that it is less than 160 ° since the stretching begins to slightly deform at the top and bottom of the image when it exceeds 55 degrees above or below the skyline. The effect of stretching up and down the image is attenuated compared to the spherical projection. The vertical angle is limited, it is imperative that it is less than 160 ° but the stretching begins to slightly deform at the top and bottom of the image when it exceeds 45 degrees above or below the skyline.Ĭan be used up to 360° (horizontally). The lines parallel to the horizon (curbs, tops of buildings) are still more or less curved. Good choice if the angle is low, recommended for architectural shots because it is the only mode that does not curve lines that are deemed to be straight lines.Ĭan be used only if the view angle is less than 180 degrees along the diagonal of the image, practice shows that beyond 90 degrees the stretching of the image is already visible along the edges and in the corners.īeyond 120 degrees, the result is no longer acceptable, because the stretching of the image causes an unpleasant loss of sharpness. PROJECTION Planar or rectilinear projection Advantages: The following tools are used to correct the geometry: 3 POINT OF VIEW, HORIZON AND VERTICAL LINES.1.4 Spherical or equirectangular projection.
