Hi there!

This article is the third in a series on running large language models (LLMs) locally. In the previous two articles, we introduced how to run Ollama locally and how to fine-tune the model’s answers by providing an external database. This article will continue to explore how to use the function-calling feature to extend the model’s capabilities and make it go further on the road to “intelligence”. Function-calling According to the OpenAI official documentation, function-calling is a way for large language models to connect to external tools....

In the previous article, we demonstrated how to run large language models (LLMs) locally using Ollama. This article focuses on enhancing LLM accuracy by allowing them to retrieve custom data from external knowledge bases, making them appear “smarter.” This article involves the concepts of LangChain and RAG, which will not be explained in detail here. Prepare the Model Visit Ollama’s model page, search for qwen, and this time we will...

With the rise of ChatGPT, LLMs (Large Language Models) have become a hot topic in the field of artificial intelligence and natural language processing. In this article, I will walk you through the process of running a large language model on your own personal computer. Pros and Cons There are many advantages to running a large language model locally: Privacy protection No expensive costs Ignore network problems Try out various open source models I think the first two advantages are enough for everyone to try....

Remember three months ago I open-sourced the ps2mc-browser project on GitHub, a magical little tool that can view and render 3D icons of PS2 archives. Occasionally pushing code, adding features, and now finally releasing its first stable version. Then I turned my attention to JetBrains’ “Open Source Development Licenses”. JetBrains Licenses for Open Source Development JetBrains is a company dedicated to building the most intelligent and efficient development tools. They...

How do we render the vertices and textures of polygons into a colorful scene? This is where OpenGL shaders come into play. Today, we’ll discuss the shaders of ps2mc-browser. To briefly introduce, ps2mc-browser is a PS2 memory card viewer capable of parsing vertex and texture data from 3D icons within PS2 memory card files and rendering them using OpenGL. In the following content, I’ll dissect the six OpenGL shaders used...

ps2mc-browser is a PS2 memory card file viewer that utilizes an OpenGL canvas to display 3D dynamic icons from the memory card. It relies on the following dependencies: Python3 WxPython Numpy ModernGL PyGlm You can find the GitHub repository here. New Features Some PS2 game memory card files contain three sets of different animated icons, corresponding to three different operations: “browse,” “copy,” and “delete.” The newly released feature allows the ps2mc-browser interface not only to display animated icons but also to interact with users and respond to mouse operations....

In the previous article, we discussed the RLE image compression algorithm used in PS2. This time, let’s delve into its texture mapping encoding algorithm—A1B5G5R5. Introduction For textures, common image encoding formats like jpg or png are not suitable. This is because images are read and rendered by the GPU. You wouldn’t want to send a jpg image over and have the GPU decode the entire image just to read one pixel, right?...

Introduction to RLE Algorithm The RLE (Run Length Encoding) algorithm is a compression method that represents file content in the form of “number of repetitions x data.” For example: given the data AAAAAABBCDDEEEEEF, by appending the number of consecutive occurrences after each character, it can be represented as 6A2B1C2D5E1F. It can be observed that the original data is 17 bytes, while the encoded data is 12 bytes, thus achieving successful compression....

After a series of previous articles laying the groundwork, the files for PS2 savegame 3D icons have all been parsed. In this article, we will begin to explore how to render the 3D icons using the following tools, aiming to achieve a rendering as close as possible to the original effect on the PS2 console. Python3 PyGame Numpy ModernGL PyGLM 01 Initialize PyGame and ModernGL The first step is to initialize PyGame, setting the window size to 640x480 and the FPS to 60....

Seeing this image, it shouldn’t be unfamiliar to seasoned players familiar with PS2. It’s the 3D icon of a game save file from the PS2 memory card management interface. In this article, we will introduce how to extract the character model from the save file. 01 Parsing Objectives A: What can we parse from the save file? All vertices and normals of the icon model Animation frames of the icon model Lighting information Textures and texture coordinates Background color and transparency B: What do we need to do?...
