Sodium
Sodium is a Minecraft performance optimization project that replaces the default rendering engine to increase frame rates and reduce stutter. It functions as a game rendering modification that applies runtime patches to the engine to change how graphics are displayed.
The project provides a customizable settings registry, allowing for the addition of new configuration options to the video menu so other extensions can integrate their own visual settings.
The rendering system implements chunk-based culling logic and buffer-based geometry caching to minimize draw calls and reduce CPU overhead. It utilizes bytecode-level engine patching and direct memory access to manipulate GPU memory and replace default rendering logic.
Features
- Minecraft Optimizations - Optimizing the rendering pipeline in Minecraft to improve frame rates and reduce stutter across hardware.
- Minecraft Client Optimizations - Performance-enhancing Minecraft mod that adds shader pack support and extends graphics settings configuration.
- Graphics Settings Persistence - Component that saves and restores user rendering preferences with automatic default regeneration.
- Draw Call Batching - Combines multiple world sections into a single draw call to reduce GPU overhead.
- Shader Pack Loaders - Runtime engine that loads and runs GLSL-based shader packs for advanced visual effects.
- Visual Effect Shaders - Uses GLSL shaders for programmable vertex and fragment processing, enabling custom visual effects.
- Occlusion Culling - Hides invisible geometry by testing bounding boxes against the view frustum and depth buffer before rendering.
- Configuration Page Hooks - Extend the video settings screen so other modules can add custom configuration pages.
- Frustum Culling Utilities - Skips rendering objects outside the camera's viewing frustum based on spatial hierarchy tests.
- Bytecode Transformers - Injects custom code into precompiled class files at load time using bytecode transformation.
- Maven Artifact Publishing - Maven publication module that distributes API and implementation artifacts for other projects to depend on.
- Video Settings Screen Extensions - Extending the video settings screen so other mods can inject their own configuration pages for graphics options.
- Settings Screen Extensions - Registers custom configuration pages into an existing options screen via a plugin hook.
