360-converter

Overview

Input one of the following type 360 image and convert it to another one.

Faces	Cubemap	Equirectangular	Stereographic

This project has been tested on:

The only thing you need is a C/C++ compiler, no other package do you need to install.

git clone https://github.com/chinhsuanwu/360-converter.git
cd 360-converter
make
make run

Just directly include the converter.hpp in folder src.

#include "src/converter.hpp"

For example, the conversion from Face to Cube, Equi and Stereo can be shown as below, other conversions can be deduced:

To convert from Face to Equi
```
Converter::Equi equi = face.toEqui();
```
To get image
```
Converter::Image img = equi.getEqui();
```
For Stereo images, you can assign TOP or DOWN, while the default will be DOWN
```
Converter::Image img = cube.toStereo(Converter::TOP).getStereo();
```
TOP DOWN

To load image

img.img = stbi_load("assets/equi.png", &w, &h, &bpp, CHANNEL_NUM);
img.w = w, img.h = h;

To write image

stbi_write_png("out/equi.png", img.w, img.h, CHANNEL_NUM, img.img, img.w*CHANNEL_NUM);

This project is using stb library for image I/O in example.cpp, great thanks to their excellent work.
