livesplit-renderer-glow

A GPU-accelerated renderer for livesplit-core using OpenGL via glow.

Features

• GPU-accelerated rendering of livesplit-core layout scenes via OpenGL.
• 4x MSAA antialiasing on all rendered content.
• Two-layer caching: the bottom layer (backgrounds, static elements) is rendered to an off-screen framebuffer and reused across frames when unchanged.
• Gradient fills: solid, vertical, and horizontal gradients are handled natively in the fragment shader.
• Text rendering via livesplit-core's built-in text engine, with optional text shadows.
• Lazy texture upload: images are decoded on the CPU and uploaded to the GPU only when first drawn.
• Path tessellation via lyon at creation time for efficient per-frame rendering.

Usage

use livesplit_renderer_glow::GlowRenderer;
use std::sync::Arc;

// During setup (with a current GL context):
let mut renderer = unsafe { GlowRenderer::new(gl) }.unwrap();

// Each frame:
let new_size = unsafe { renderer.render(&layout_state, &image_cache, [width, height]) };

// On shutdown:
unsafe { renderer.destroy() };

Requirements

• OpenGL 3.1+ (GLSL 1.40)
• A valid, current OpenGL context wrapped in Arc<glow::Context>
