Corridor Crawler Outpainting is an innovative extension designed for the automatic1111/stable-diffusion-webui. It is a powerful tool that allows users to generate and animate hallways using the Stable Diffusion model. The primary purpose of this extension is to create intricate and detailed outpaintings of corridors, making it an excellent tool for artists, game developers, and anyone interested in digital art.
The Corridor Crawler Outpainting is designed to work with the depth-to-image model at a resolution of 512. However, it is flexible and can be tweaked to work with other models as well. The depth-to-image model, also known as the Stable Diffusion model, plays a crucial role in the process. Stable Diffusion is a powerful model that uses a unique approach to generate images. It uses a diffusion process to gradually transform a random noise into a coherent image. This model is the backbone of the Corridor Crawler Outpainting, enabling it to generate detailed and realistic images.

2. Select the model: After running the automatic1111/stable-diffusion-webui, you need to select the model you want to use. The recommended model for the Corridor Crawler Outpainting is the 512-depth-ema.ckpt. This model is designed to work well with the extension and produce high-quality images.
3. Go to "img2img" then select the tab "Inpaint upload": Next, navigate to the "img2img" tab and select the "Inpaint upload" sub-tab. This is where you will upload the images you want to transform.
4. Select the mask image: For the mask image, you should select "default-mask.png" from the Corridor Crawler Outpainting repository. This mask image is designed to work well with the extension. The other image can be your choice.
5. Select "Corridor Crawler Outpainting" from the Scripts dropdown menu: Finally, select the "Corridor Crawler Outpainting" from the Scripts dropdown menu. This will activate the extension and allow you to start generating and animating hallways.
6. Configure your chosen prefab image and other settings: After selecting the script, you can configure your chosen prefab image and other settings according to your preferences. This includes specifying the positive and negative prompts, the sampling steps, the CFG scale, and the denoising strength.
Understanding the Python Script
The Corridor Crawler Outpainting extension is powered by a Python script named corridor-crawler-outpainting.py. This script is responsible for the core functionality of the extension, including image processing, animation generation, and UI management. The script is structured as a class named Script, which inherits from the scripts.Script class. This class contains several methods that define the behavior of the extension. The title method returns the title of the script, which is displayed in the dropdown menu of the automatic1111/stable-diffusion-webui. The show method determines when the script should be shown in the dropdown menu. It returns a boolean value that indicates whether the current tab is img2img. The ui method defines the user interface of the script. It uses the Gradio library to create various UI components, such as sliders, checkboxes, and text boxes. These components allow users to configure the settings of the extension. The run method is where the main processing happens. It takes several parameters, including the model object and the values returned by the ui method. It uses these parameters to generate new images and animations. The method includes several helper functions, such as newStep and animation, which are used to generate new steps and animations, respectively. Understanding this script can provide valuable insights into the inner workings of the Corridor Crawler Outpainting. It can help users to better understand how the extension generates and animates hallways, and how they can tweak the settings to achieve their desired results.
The Stable Diffusion Model & Use Cases
The Stable Diffusion model is a key component of the Corridor Crawler Outpainting. It is a type of generative model that uses a diffusion process to transform a random noise into a coherent image. The model starts with a random noise and gradually refines it over several steps, each time making the image more similar to the target image. This process is guided by a learned neural network that predicts the next step in the diffusion process. In the context of the Corridor Crawler Outpainting, the Stable Diffusion model is used to generate the hallways. The model takes the input image and the mask image, and uses them to generate a new image that extends the hallway. This process is repeated several times to create a long, winding hallway.
