How do I set up a basic 3D scene in Clinch?

Load Clinch in your Common Lisp environment, create a window via SDL2, define transforms and nodes for object hierarchy, and use entities with shaders to render meshes. The README highlights using the REPL for live coding to iterate quickly on changes.

Clinch vs other Lisp graphics engines like Sketch or CL-OpenGL?

Clinch focuses on modularity and live coding with a multithreaded REPL, while Sketch is more for 2D creative coding and CL-OpenGL offers lower-level bindings. Clinch is better for rapid 3D/2D prototyping, but may have a steeper learning curve for beginners.

Can Clinch handle 2D games or is it only for 3D?

Yes, Clinch supports 2D graphics through plugins like Cairo for vector graphics and has features for textures and pixel buffers, making it suitable for both 2D and 3D applications, as noted in the README's integration list.

What system requirements are needed to run Clinch?

Clinch requires a Common Lisp implementation, OpenGL support for graphics, and SDL2 libraries for multimedia. Additional dependencies like FreeImage or ODE may be needed for plugins, based on the README's plugin ecosystem.

How does live coding work with multithreading in Clinch?

Clinch runs the window in a separate thread, allowing code modifications in the REPL while the application is active. Changes to objects like shaders or entities can be applied without restarting, facilitating rapid development as described in the README.

Is there good documentation or tutorials for Clinch?

The README provides an overview and architecture, but detailed documentation is limited. Developers often rely on the source code and modular examples, with community resources being sparse due to the niche Common Lisp focus.

CLinch — Common Lisp OpenGL Graphics Engine

What is CLinch?

Clinch is a 3D/2D graphics engine for Common Lisp that leverages modern OpenGL to create games, visualizations, and productivity tools. It emphasizes live coding in a multithreaded environment, allowing developers to modify the engine directly from the REPL for rapid iteration. The engine provides modular components like transforms, nodes, buffers, textures, and shaders that can be used independently or combined.

Target Audience

Common Lisp developers building 3D/2D games, visualizations, or productivity tools who value live coding and REPL-driven development. It suits those familiar with graphics programming who want a flexible, low-abstraction engine they can tailor without imposed design patterns.

Value Proposition

Developers choose Clinch for its live coding capabilities in a multithreaded setup, enabling on-the-fly changes without restarting. Its modular architecture avoids unnecessary abstractions, allowing direct use of OpenGL features and integration with plugins like ODE for physics, Cairo for 2D graphics, and FreeImage for textures.

Common Lisp 3D/2D Graphics Engine for OpenGL

Use Cases

Best For

Rapid prototyping of 3D/2D applications in Common Lisp with live coding from the REPL.
Building modular graphics applications where components like buffers, textures, or shaders need to be used independently.
Developing games or visualizations requiring integration of modern OpenGL features, SDL2 for multimedia, and plugins for physics or asset importing.
Creating productivity tools or graphical shells that combine 3D graphics, 2D vector graphics, text rendering, and shaders.
Projects needing a flexible, low-abstraction engine that avoids wrapping libraries and allows direct customization.
Educational or experimental graphics programming in Lisp with an emphasis on simplicity and intuitive design.

Not Ideal For

Projects requiring stable, production-ready features like complete 3D animation or GUI tools, as these are marked 'Current Development' or 'Experimental' in the README.
Teams working in programming languages other than Common Lisp, since Clinch is built specifically for Lisp and cannot be easily integrated elsewhere.
Developers seeking extensive community support, tutorials, or pre-built assets, due to Common Lisp's smaller graphics ecosystem and niche adoption.

Pros & Cons

Pros

Live REPL Coding

Enables on-the-fly code changes in a multithreaded environment without restarting, as emphasized in the README's features for rapid iteration and debugging.

Modular Architecture

Components like transforms, nodes, buffers, and textures can be used independently, allowing for flexible, tailored graphics pipelines without imposed design patterns.

Modern OpenGL Features

Supports shaders, GPU buffers, and real-time OpenGL object inspection, leveraging up-to-date graphics capabilities for high-performance 3D/2D rendering.

Comprehensive Multimedia Integration

Uses SDL2 for windowing, controller support, sound, and music, providing robust cross-platform multimedia handling as listed in the README's key features.

Cons

Incomplete Core Features

Key functionalities like 3D asset importing, 3D animation, and 3D GUI are labeled 'Current Development' or 'Experimental' in the README, limiting immediate usability for full-scale projects.

Niche Language Dependency

Built exclusively for Common Lisp, it inherits the language's smaller ecosystem, which can result in fewer resources, libraries, and community support compared to engines in more popular languages.

Low-Abstraction Complexity

Avoids wrapping libraries and requires direct OpenGL knowledge, making it less accessible for developers unfamiliar with graphics programming or seeking higher-level abstractions.
