Cubemaps are supported natively in graphics hardware so they're really quick to transform and render, because of this there's a unified method for rendering them in games. The cube is usually centered on the current viewpoint or camera. This means, when used as a backdrop or skybox it always appears infinitely distant. If you turn on wireframe mode in any 3d engine using a cubemap skybox, you'll see the geometry of the box.
In the end it's just a regular mesh object. When used for reflections, the reflection cubemap is usually centered on the mesh object. The viewing angle bounces off the mesh surface at an angle opposite to the surface normals, so it points to particular parts of the cube map.
Cubemaps can also be used for soft ambient-occlusion-like environment lighting, by using a diffusely convolved cubemap. Another method is a Spherical environment mapwhich maps a single image to use as a reflection similar to the behavior of a Billboard.
A cube map has to be created with some angular distortion in order to display a seamless panoramic image. A cube map is always displayed from a viewpoint in the center of a cube mesh. This means the center of each cube face is closer to you than the edges and corners are. To counteract this, a cube map needs angular distortion. This distortion becomes more obvious when you view it at any other angle, other than from the center of a cube.
The bitmaps for each of the six sides need to be square, each needs to be powers-of-two in size,etc. Usually for games you store the bitmaps all in one file using DDS or another compressed format, though some editors prefer them stored as six separate bitmaps then compress them internally.
Warning: The render cannot be canceled once the object is picked, so save your Max file before rendering, in case Max freezes! You can use V-Ray's "Box" camera type to render a cubemap with no lighting seams. Because V-Ray uses Global Illumination, if you try to use six cameras it will add seams between the six separate lighting solutions. Their example panorama avoids the errors because it has a flat-colored floor.
But if there was a pattern there grass, carpet, etc. If you need to convert the vertical cubecross into six cube faces, you can use the Material Editor to do it:. Use the x86 version unless you're running a 64bit OS. The DDS format does not actually store the images in a horizontal layoutFacebook recognizes and processes photos by looking for camera-specific metadata found in photos taken using ready cameras.
This information is embedded in photo's Exif Exchangeable image file format metadata tags, and if you're sharing photos straight from camera, Facebook should automatically process and present them as interactive photos.
However, when metadata has been stripped from pictures or never existed in the first place, Facebook might not be able to tell that your photo is a photo. Sometimes, metadata is stripped during image editing, but other workflows can also strip metadata from pictures.
Here are some common reasons metadata might be missing:. In these cases, the correct metadata must be injected into your photos before they can be shared as photos. To inject metadata, you'll need to edit the XMP tags in the Exif data. Here are options for doing so:.
Most photographer-targeted Exif editors do allow the editing of the Exif XMP tag "ProjectionType," but if you're technical, you can use the popular command-line tool, exiftool. When uploading directly from a mobile device, Facebook first looks for spherical metadata. If, for some reason you have edited or otherwise lost metadata, you have the following options:.
If you want to create an image that has the correct metadata to be interpreted aswe offer the following templates to help you get started. These can be used to create photos and panoramas without injecting metadata, as it is built into the template.
Cylindrical panorama templates are described by horizontal field of view FOV and vertical FOV, and there is also a full spherical equirectangular template available. See a video example of using one of the panorama templates.
If creating your own Photo, using special hardware or cameras, or uploading from 3rd party software, the following resolution, format, and size guidelines apply. Mobile uploads have additional limitations applied during upload. If you want to be closer to the maximum value we recommend you upload from web. Due to bandwidth considerations the maximum resolution for mobile might be closer to 6k-8k for long edge; therefore, you could select a larger image on mobile, but it might be resized to this maximum size during upload to Facebook.
If you'd prefer to use exiftool to inject cylindrical panorama metadata, you can use the following commands:. I made my own photo and followed your instructions. Why does my photo look so strange? Make sure that the FOV is consistent with what you want. Use one of the metadata editors discussed above to check these values. Using a standard image editor to edit equirectangular projections can be extremely challenging. You're editing pixels in a non-linear space that contains a lot of distortion.Python implementation of convertion between equirectangular, cubemap and perspective.
