## What is i3DSteroid360?

Ricoh's Theta and others, spherical panorama cameras became readily available, and by using VR viewer everyone can enjoy full spherical stereoscopic images with immersive feeling.
Unfortunately, even if you view same image on the left and right with the VR viewer, you will not get a stereoscopic effect.
You need two equirectangular images shot at the same distance from the subjects, called "cha-cha shot" for decent stereoscopic effects.

In case of twin spherical shots on THETA for 3D360 photo, special image processing is required for the geometrical alignment, which is different from regular non spherical 3D images such as;
1) No cropping allowed in the equirectangular images and the deformation have to be kept within the equirectangular shape.
2) Pseudo stereoscopic parts exist in parts of the equirectangular pair have to be swapped for decent stereo.

This i3DSteroid360 APP is for 3D360 equirectangular alignment and VR viewing application.

Ver1.60
- Fixed the application crash problem when image file is opened from the folder which have large number files.
- Fixed the portrait image file orientation problem.
- Improved the thumbnails view and the image scrolling performance.

### 5/5 — コレは面白い！神アプリ！

*2025-01-12*

Theta SC2 で、たまたま数歩離れて 2 枚撮影した天球画像があったため、i3DSteroid360 で試してみたが、左右の像が重ならず今ひとつ。

価値を理解できずお蔵入り…だったのだが、
作者様 web サイトの i3DSteroid360  ページに「Theta で撮影の際、離す距離は 2 から 3 センチに留めること」の記載。

コレに従って撮影した 2 枚の天球画像 を i3DSteroid360  へ取り込むとすげ〜臨場感(汗

Theta SC2 の天球画像は、Meta Quest3 へ取り込むよりも 1000 円程度の折りたたみ VR グラス + i3DSteroid360 で体験する方が遥かに良い！

作者様のアプリは、どれもこれも、Theta だったり Looking Glass だったりとマニアックなハードウェアを対象としていて、しかも、技術検証的な使い勝手だったりで、刺さるユーザーがごく少数なはず。

公開してくださり感謝。

### 1/5 — App does not work with iPhone camera. A total waste of money

*2017-12-05*

The iPhone version of this app is horrible it does not work at all with my iphone camera it will only let you try to make 3-D pictures with your library it’s very confusing hard to use And no tech-support at all. avoid at all costs. My partner has the android version which works great but they’ve done at lousy job trying to make it work with Apple
