Image files are composed of digital data in one of image file format that can be rasterized for use on a computer display or printer. An image file format may store data in uncompressed, compressed, or vector formats. A raster graphics image is a dot matrix data structure, representing a generally rectangular grid of pixels, or points of color.
As opposed to the raster image formats, vector image formats contain a geometric description which can be rendered smoothly at any desired display size. Convert image online.

How can I convert a regular png image into a degree image to add to a scene? Converting a regular png to a degree image for scene in Google Expeditions? Getting StartediOSChrome. Community content may not be verified or up-to-date. Learn more. Recommended Answer Recommended Answers 1. Gold Product Expert Graham Bowman. Recommended Answer. Oh I see what you mean. It's possible in Photoshop if you have Creative Cloud.
I've found that you need to merge your new graphic down onto the layer before moving to a new point in the view, which is a bit of a pain if you want to go back and edit it. I'd be interested to see if anyone knows of a more suitable tool for this job? One where you can import multiple "flat" images and move them around within a sphere.This tutorial explains how to convert still images to degree images.
There are tons of image converter websites and software available, which can be used to convert images from one format to another. But, none of them has the option to convert a still image to a degree image. So, after spending hours on the web, I have come across some solutions to easily convert still images into degree images. You can then save or share the resulting degree images.
Follow the steps below to do the same. Step 2 : When you click the button, it will ask you to choose the still image which you want to convert. Then you can select any image you want from your PC.
Step 3 : As soon as you do that, it will automatically convert the still image into a degree image. You can follow the steps explained below to do so. When you do that, it will instantly convert the still image into a degree image. So, if you have been looking for a way to convert normal images to degree, then using any of these web applications is probably the best option for you. They are super simple to use and you can convert still images to degree images in no time.
Graphic Design Stack Exchange is a question and answer site for Graphic Design professionals, students, and enthusiasts. It only takes a minute to sign up. I have a regular panorama image. This is the image I want to convert HR link. Equirectangular image presents a sphere, it's distorted so that meridians and parallels on the sphere are shown as straight vertical and horizontal lines.
An example from Wikipedia:. In the left there's a spherical map and in the right there's the equivalent plane map, the equirectangular projection from sphere to a rectangle. There's no stretching on the equator, but the the image is stretched horizontally elsewhere. The more stretching the further the point is from the equator. Top and bottom edges contain actually only single points - the poles. That reflects the fact the distance between the poles along the sphere is exactly half of the full round trip along the equator.
You wanted to convert your image to equirectangular. Seemingly the proportions areso it is equirectangular already if the corresponding sphere is this:. Half of the image is hidden behind the sphere, but there it is. As you see, top and bottom edges of your image are pinched to points, the poles.
I think you see this as an useless piece of math sophistry, you expected something else. I guess you want. It shows this:.
Converting a fisheye image into a panoramic, spherical or perspective projection
Curved fence and horizon obviously are unwanted, but the sun is still quite round. That's because it's much smaller and it's near the equator line. One can straighten the original image area with compensating distortion ie.
Affinity Photo allows image edits in live projection mode. The edits are applied to underlying equirectangular image, but one watches the projection on the sphere. Here's a coarse warping attempt:. As well one can paste the original image and merge it to bare background layer, which is under Live projection:.
But this is not a general fix. My opinion is that mapping the environment as a single image onto a sphere and watching it from the midpoint can be plausible virtual reality only if the mapped scene is so far away that it cannot have any perspective.
The distortion should live as the watching direction changes. This answer was totally rewritten after checking this much later case: How can I paint equirectangular degree images?
First your canvas needs to be at one exact proportion. On a cylindrical projection from a sphere you have a specific deformation on the projection due the vertical projected dimension versus the real height of that segment, so you need to compensate that when you draw your cartoon at a flat canvas.VR, stands for virtual reality, has triggered an incredible storm around the world in recent two years.
With a VR headsets, you can interact with a replicated environment. And all sensory experience sight, touch, hearing and smell is created in a virtual world. However, there comes a problem — VR video is still in its infancy by now, which means VR video resource are limited.

Instructions for measuring fisheye center and radius, required if the fisheye is from a real camera sensor Applying correction to convert a real fisheye to an idealised fisheye The following documents various transformations from fisheye into other projection types, specifically standard perspective as per a pinhole camera, panorama and spherical projections.
Fisheye images capture a wide field of view, traditionally one thinks of degrees but the mathematical definition extends past that and indeed there are many physical fisheye lenses that extend past degrees. The general options for the software include the dimensions of the output image as well as the field of view of the output panoramic or perspective frustum. Some other requirements arise from imperfect fisheye capture such as the fisheye not being centered on the input image, the fisheye not be aligned with the intended axis, and the fisheye being of any angle.
Another characteristic of real fisheye images is their lack of linearity with radius on the image, while this is not addressed here as it requires a lens calibration, it is a straightforward correction to make. The usual approach for such image transformations is to perform the inverse mapping.
That is, one needs to consider each pixel in the output image and map backwards to find the closest pixel in the input image fisheye. In this way every pixel in the output image is found compared to a forward mappingit also means that the performance is governed by the resolution of the output image and supersampling irrespective of the size of the input image. A key aspect of these mappings is also to perform some sort of antialiasing, the solutions here use a simple supersampling approach.
This is not meant to be a final application but rather something you integrate into your code base. They all operate on a RGB buffer fisheye image in memory. For each test utility the usage message is provided. The source images for the examples provided are provided along with the command line that generated them. A fisheye like other projections is one of many ways of mapping a 3D world onto a 2D plane, it is no more or less "distorted" than other projections including a rectangular perspective projection A critical consideration is antialiasing, required when sampling any discrete signal.

The approach here is a simple supersampling antialiasing, that is, each pixel in the output image is subdivided into a 2x2, 3x The final value for the output pixel is the weighted average of the inverse mapped subsamples. There is a sense in which the image plane is considered to be a continuous function. Since the number of samples that are inverse mapped is the principle determinant of performance, high levels of antialiasing can be very expensive, typically 2x2 or 3x3 are sufficient especially for images captured from video in which neighbouring pixels are not independent in the first place.
For example a 3x3 antialiasing is 9 times slower than no antialiasing. Default perspective view looking forwards, degrees horizontal field of view. The vertical aperture is automatically adjusted to match the width and height.
Controls are provided for any angle fisheye as well as fisheyes that are not level or tilted, noting that the exact order of the correction rotations may need to be considered for particular cases. Note that a perspective projection is not defined for greater than degrees, indeed it gets increasingly inefficient past around degrees. The field of view can be adjusted as well as the viewing direction.
The following example is a degrees horizontal field of view and looking upwards by 30 degrees.
