The +composite is the one place the range comes down, through ACES. + +**Two UI passes.** `engine.ui` routes every command to a pass. Particle +clouds and filled rectangles default to the world pass, which is painted into +the HDR buffer before post-processing; text, outlines, bars and sprites +default to the HUD pass, painted sharp on top afterwards. A panel splits: fill +to the world, border to the HUD. `ui.begin_world()`, `ui.begin_hud()` and +`ui.end_pass()` override the default for a run of commands. A game that draws +its whole picture as screen-space matter gets bloom, grade, lens and grain on +all of it, and a readable interface over that. + +**What the composite does, in order:** shockwave refraction, heat haze, barrel +lens, chromatic aberration, unsharp mask, floor reflection, exposure, +screen-space indirect light (matter near a lit thing is lit by it), bloom, +halation, light shafts, lens flare, flash, ACES tonemap, lift/gain grade, +tint, contrast, saturation, vignette, shadow-weighted grain, ordered dither, +scanlines. Every standing parameter is a field on `RenderConfig`; the moments +are on `engine.fx`. + +**`engine.fx` (ScreenFx).** Fire-and-forget effects that decay on their own: +`shockwave(x, y, strength)`, `flash(color, strength)`, +`light_shaft_at(x, y, strength)` or `auto_shafts = true` to stream from +whatever is brightest on screen, `reflect_at(y, strength, fade)` for a glossy +floor, and `haze` for heat shimmer. Coordinates are UI pixels. + +**Lights and shadows.** `engine.fx.light(x, y, radius, color, intensity)` +and `engine.fx.ambient`. The glyph pass writes an occluder buffer (matter, +never floors or panel fills); the light pass marches shadows through it +from every light and the composite multiplies the scene by the result. +Emissive matter lights itself. `config.persistence` keeps a decaying copy +of last frame's scene under this one, for motion trails. + +**GPU density entities.** `engine.init_gpu_density(n)` and +`engine.queue_gpu_density_entity(data)`: sixteen bones become millions of +particles derived in the vertex shader from the instance index, with +breathing, jitter and matter that comes loose as `hp` falls. Nothing per +particle ever leaves the GPU. See `examples/colossus.rs`. + +**Sound.** A `MathAudioSource` now carries a pitch envelope, a second +partial, a noise mix, biquad or comb filters, drive, a reverb send, and a +start delay, and the output thread honours all of it, with separate music +and effects buses, ducking, a master reverb and a soft limiter. A blow is a +crack, a thud and a ring; before, it was a sine. + +**Also:** `render_scale` renders the scene at a fraction of the window and +upsamples; `fxaa` runs a real FXAA 3.11 pass between the composite and the +HUD; `shake_pixels` moves the world pass with camera trauma while the HUD +stays put; `vsync` waits for the display. ## Quick start -Requires a Rust toolchain and an OpenGL 3.3 capable GPU. +You need a Rust toolchain (stable) and a GPU with OpenGL 3.3 or newer. + +- **Windows:** nothing else. +- **macOS:** nothing else. macOS stops at OpenGL 4.1, so `apotheosis` (which uses 4.3 compute shaders) will not run there; every other demo does. +- **Linux:** the audio backend needs the ALSA headers: `sudo apt install libasound2-dev pkg-config` (Debian/Ubuntu) or `sudo dnf install alsa-lib-devel` (Fedora). ```bash git clone https://github.com/Mattbusel/proof-engine.git cd proof-engine -cargo run --release --example hello_glyph # smallest possible program -cargo run --release --example galaxy -cargo run --release --example supernova cargo run --release --example convergence # the demo in the screenshots ``` -Other examples: `chaos_field`, `particle_demo`, `force_fields`, `amorphous_entity`, `strange_attractors`, `full_combat`, `math_rain`, `heartbeat`, `showcase`, `playground`, `sculptor`, `apotheosis`, `colossus`.
