Cube Map Generator CLI

Overview

This CLI tool generates cube map images from a panorama image folder. It provides functionalities to specify the size of each face of the cube map and the quality of the generated images.

Installation

1. Download the Executable

   • Go to the Releases page of this repository.
   • Download the latest version of the executable file for your operating system (Windows, macOS, or Linux).

2. Install ImageMagick

   • This tool requires ImageMagick to be installed on your system. On Windows, it's advisable to add ImageMagick to the PATH for ease of use.

3. Run the Executable

   • You can run it from the command line by navigating to the directory where the executable is located and executing the file.

Folder Structure

The input panorama folder should have the following structure:

input
├── folder_1
│ ├── panorama.jpg
│ └── panorama_low.jpg
├── folder_2
│ ├── panorama.jpg
│ └── panorama_low.jpg
└── ...

The input panorama quality folder should have the following structure:

input-quality
├── panorama-1.jpg
├── panorama-1.jpg
└── ...

The input panorama low folder should have the following structure:

Note: The low-quality image file name must contain the name of the high-quality image.

input-low
├── panorama-1_low.jpg
├── panorama-1_abc.jpg
└── ...

The output panorama folder has the following structure:

output
├── folder_1
│   ├── tile
│   │   └── ...
│   └── tile_low
│       └── ...
├── folder_2
│   ├── tile
│   │   └── ...
│   └── tile_low
│       └── ...
└── ...

Usage

The CLI tool accepts the following arguments and options:

$ cubemap-generator [options]

Options:

• ``-ig, --input-generate `: Generate data panoramas.
• '-g, --generate: If you use this flag when the --input-generate flag is present, it will both cut panorama and generate, otherwise it will only generate panorama data.
• -i, --input <input>: Specify the path to the input panorama image folder. Example: --input /path/to/input/folder.
• -iq, --input-quality <inputQuality>: Specify the path to the low-quality input panorama image quality folder. Example: --input-quality /path/to/input_quality/folder.
• -il, --input-low <inputLow>: Specify the path to the low-quality input panorama image folder. Example: --input-low /path/to/input_low/folder.
• -o, --output <output>: Specify the path to the output panorama image folder. Example: --output /path/to/output/folder.
• -s, --size <size>: Specify the size (width and height) of each face of the cube map. Must be divisible by 2, 4, 8, or 16. Example: --size 375 (e.g., if each cube map face is 1500, then the size when divided by 4 is 375).
• -q, --quality <quality>: Specify the quality of the image as a number from 0 to 100. Higher values indicate better quality. Default is 90. Example: --quality 80.
• -p, --panorama <panoramaName>: Specify the name of the panorama file. Example: --panorama panorama.jpg. If the panorama image name is in the format [name].[type], the low-quality image name will be "[name]_low.[type]". The low-quality image name must follow this format. Default value is panorama.jpg.

Note: Either -i (input) option must be provided, or both -iq (input-quality) and -il (input-low) options must be provided.

Example:

$ cubemap-generator \
    --input /path/to/input/folder \
    --input-quality /path/to/input_quality/folder \
    --input-low /path/to/input_low/folder \
    --output /path/to/output/folder \
    --size 375 \
    --quality 80 \
    --panorama panorama.jpg

The command will generate cube map images from the panoramic images located in the input folder, using the file panorama.jpg as the source panorama. Each face of the cube map will have a size of 1500 pixels, where 375 represents the cropped images from the 1500-pixel faces of the cube. The resulting cube map images will be saved in the output folder with a quality setting of 80.
