glslViewer is a console-based OpenGL sandbox designed for visualizing and experimenting with GLSL shaders. It allows users to run shaders without requiring a graphical user interface, making it suitable for quick prototyping, educational purposes, and integration with other tools. glslViewer achieves this by directly interacting with the OpenGL rendering pipeline through standard input/output or OSC, offering a flexible environment for shader development and debugging.
glslViewer stands out with its extensive feature set, supporting a wide array of functionalities such as texture import, geometry loading, uniform control, and interactive commands via console or OSC. Its ability to handle various shader types (fragment and vertex), incorporate external dependencies, and offer hot reloading enhances developer workflow. The integration with WebAssembly allows for cross-platform deployment, further increasing its versatility.
- Shader Support: Supports both fragment and vertex shaders written in GLSL.
- Texture Handling: Handles various texture formats including PNG, BMP, JPG, and audio/video textures.
- Uniform Control: Allows passing custom uniforms (float, int, vec2, vec3, vec4) via console or OSC.
- Geometry Loading: Imports LST, PLY, OBJ, and GLTF files, including dependencies.
- Interactive Commands: Provides interactive commands through POSIX console IN/OUT or OSC.
- Debugging Tools: Offers different debug modes such as histograms, texture display, and bounding box visualization.
- Cross-Platform: Supports compilation and execution on Linux, macOS, Windows, and WebAssembly.
glslViewer is an actively maintained project with a solid track record of updates and bug fixes. Regular commits and a responsive community indicate ongoing development. The comprehensive documentation and wiki pages further enhance usability and ease of integration. The project's maturity is evidenced by its active development, clear documentation, and a growing user base.
glslViewer benefits developers, artists, and researchers seeking a flexible and powerful tool for experimenting with and debugging GLSL shaders. It streamlines the shader development process by eliminating the need for a UI and enabling easy integration with external tools and workflows. It offers a valuable alternative to traditional shader editors and provides a convenient environment for real-time shader testing and visualization.
