feat: data-driven backgrounds + Balatro shader wallpaper by AndrewAltimit · Pull Request #71 · AndrewAltimit/oasis-os

AndrewAltimit · 2026-03-13T14:20:39Z

Summary

Data-driven background animations: New [[background_layers]] TOML config supporting waves, grids, scanlines, radar sweeps, glass shards, and more via oasis-vector
Balatro shader wallpaper: New oasis-shader crate with CPU software renderer implementing the Balatro card game swirl effect (Shadertoy XXtBRr). Renders at 1/3 internal resolution with nearest-neighbor upscale for performance
Per-backend integration: SDL3 (load_texture/blit), WASM (putImageData on Canvas 2D), UE5/FFI (software blit_rgba), PSP (shader layers filtered out)
Cyberpunk skin: Balatro shader with neon cyan/magenta/dark palette as animated wallpaper

Test plan

cargo build --workspace --release compiles clean
cargo clippy --workspace -- -D warnings passes
cargo test --workspace passes
OASIS_SKIN=cyberpunk cargo run -p oasis-app --release shows animated Balatro shader background with icons/bars visible on top
./scripts/build-wasm.sh builds WASM; shader visible at localhost:8080 with cyberpunk skin
Skins without shader layers render unchanged
PSP EBOOT builds without shader dependency

Add a full data-driven background animation system that makes decorative background effects available to all skins via TOML configuration, replacing the previously hardcoded altimit-only vector overlay. Core infrastructure: - AnimClock: unified animation time source bridging frames and wall-clock - BackgroundLayer/BackgroundScene: composable layer system with 12 layer kinds (grid, dot_grid, wireframe_sphere, radar_sweep, concentric_rings, glass_shard, scanlines, eq_bars, crosshair, floating_polygons, pulsing_core, waves) with anchor positioning and animation params - Factory functions in backgrounds.rs for each layer kind - Waves layer: Vanta.js-inspired undulating surface with filled depth bands, perspective shading, and crest highlights - StrokeRoundedRect VectorOp for neon outline rendering - Entrance animations (fade_in, scale_up, slide_up) with per-icon stagger - Focus glow ring on selected dashboard icon - New icon presets: "geometric" and "hud" Theme integration: - [[background_layers]] TOML array-of-tables schema with per-layer kind, color, position, and animation config - [background_performance] section for complexity_budget / reduced_motion - ActiveTheme derivation from skin TOML and built-in presets - Render gate decoupled from icon_style across all 6 backends Per-skin profiles: - cyberpunk: dual-layer wave interference (cyan swells + magenta ripples) with scanlines - altimit: digital terrain waves + perspective grid floor - retro-cga: CRT scanlines + choppy signal waves + phosphor undertow + pulsing core - vaporwave, xp, macos, paper, solarized: subtle decorative layers - terminal, tactical, corrupted, modern, agent-terminal: built-in layers PSP guardrails: - Filters out expensive layers (FloatingPolygons, EqBars, Waves) - Max 4 layers, complexity budget capped at 100, reduced motion forced Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Add a new `oasis-shader` crate that implements Shadertoy-style fragment shader backgrounds. The first shader is the Balatro card game swirl effect (polar-coordinate twist + 5-iteration distortion + 3-color weighting). The software renderer evaluates the shader math per-pixel in Rust at 1/3 internal resolution with nearest-neighbor upscale for performance. Each backend blits the result as a wallpaper layer: - SDL3: uses backend's own load_texture/blit pipeline - WASM: putImageData on the main 2D canvas - UE5/FFI: software renderer → blit_rgba into shared buffer - PSP: shader layers filtered out (no programmable shaders) Theme integration via `[[background_layers]]` with `kind = "shader"`: ```toml [[background_layers]] kind = "shader" shader = "balatro" [background_layers.shader_params] color_1 = "#00F0FF" color_2 = "#FF2060" color_3 = "#0A0A14" speed = 1.0 contrast = 3.5 ``` Hides wallpaper and content_bg SDI objects when a shader layer is active so the shader renders as the true background behind all UI elements.

Gemini AI Code Review

Issues (if any)

[BUG] crates/oasis-vector/src/backgrounds.rs:178 - Unbounded drift causes glass_shard to permanently leave screen
- drift_x and drift_y grow continuously with time but the mapped coordinates are not wrapped against screen dimensions, so shards drift off-screen and disappear.
- Apply modulo wrapping against w and h for final coordinates, similar to the logic in floating_polygons.
[WARNING] crates/oasis-core/src/vector_overlay.rs:99 - Redundant allocations in hot path
- get_shader_layer clones name and params (containing a HashMap and Vec) on every call, which is called multiple times per frame.
- Return references (Option<(&str, &ShaderParams)>) or cache the active shader layer status to avoid repeated lookups.
[WARNING] crates/oasis-shader/src/software.rs:90 - High-frequency Vec allocation
- SoftwareShaderRenderer::render_balatro allocates a new lo_buf (~58KB for 480x272) every frame.
- Store lo_buf as a struct field and .resize() it alongside the pixel buffer.

Suggestions (if any)

crates/oasis-backend-sdl/src/shader_bridge.rs:53 - Uploading and destroying a static SDL texture every frame via load_texture/destroy_texture is suboptimal; consider caching a streaming SDL texture updated with SDL_UpdateTexture.
www/index.html:43 - Comment  contradicts the WASM implementation, which blits directly to the existing 2D canvas via putImageData with no WebGL2 canvas.

Notes

1 claim(s) were automatically filtered as potential hallucinations (file:line content didn't match claims)
The CPU software renderer fallback correctly mirrors GLSL distortion/lighting logic and uses a 1/3 scale optimization that should keep performance reasonable.
In crates/oasis-ffi/src/lib.rs, software_shader is initialized with the initial viewport dimensions but does not appear to handle resizing if the UE5 viewport changes dimensions mid-session. [UNVERIFIED - file not in PR]

Fixed Issues

BUG: glass_shard unbounded drift (crates/oasis-vector/src/background.rs:277-282) - Applied rem_euclid(w) / rem_euclid(h) wrapping to drift_x and drift_y so shards loop across the viewport instead of drifting off-screen permanently.
WARNING: lo_buf per-frame allocation (crates/oasis-shader/src/software.rs:91) - Moved lo_buf into the SoftwareShaderRenderer struct as a cached field, resized alongside pixel_buf in new() and resize(). Eliminates ~58KB allocation per frame.

Ignored Issues

WARNING: get_shader_layer redundant clones (crates/oasis-core/src/vector_overlay.rs:74) - Verified callsites: 3 of 6 consume info.params.colors/info.params.floats by moving, so returning references would just move cloning to those callsites. The 3 .is_some() checks waste a small clone but the overhead is negligible. Not worth the API complexity change.
Suggestion: SDL texture caching (crates/oasis-backend-sdl/src/shader_bridge.rs:53) - Optimization suggestion, not a bug. Deferred.

Commit: 447a12d

Fixed Issues

BUG: floating_polygons negative drift wrapping (crates/oasis-vector/src/backgrounds.rs:304-307) — Rust's % operator preserves sign of dividend, so negative drift_x/drift_y values produced negative coordinates, sending polygons off-screen. Replaced % with .rem_euclid() to always produce non-negative wrapped coordinates, matching the fix already applied to glass_shard in iteration 1.

Ignored Issues

WARNING: UE5 SoftwareShaderRenderer resize (crates/oasis-ffi/src/lib.rs:406) — The FFI API has no resize mechanism; width/height are fixed at oasis_create time and never change. The renderer is lazily initialized with those same dimensions via get_or_insert_with. No desync is possible.
Suggestion: SDL texture caching (crates/oasis-backend-sdl/src/shader_bridge.rs:53) — Optimization suggestion, not a bug. Already deferred in iteration 1.
Suggestion: HTML comment mismatch (www/index.html:43) — Cosmetic. Already deferred in iteration 1.

Issues (if any)

[BUG] crates/oasis-vector/src/background.rs:309 - GlassShard drift animation snaps visually instead of wrapping seamlessly
- Wrapping drift_x and drift_y before multiplying with point coordinates causes the polygon to jump back to its starting position when drift resets to 0.
- How to fix: Remove .rem_euclid() in background.rs and apply it to the final world-space coordinate inside crates/oasis-vector/src/backgrounds.rs:188 (e.g., ((px * w as f32) as i32 + drift_x as i32).rem_euclid(w as i32)).

Previous Issues

[STILL UNRESOLVED] crates/oasis-vector/src/backgrounds.rs:297 - floating_polygons panics when viewport dimensions are zero (early return for w == 0 || h == 0 is still missing).
[STILL UNRESOLVED] crates/oasis-ffi/src/lib.rs:410 - UE5 software shader is static and never animates (still hardcodes time to 0.0).
[STILL UNRESOLVED] crates/oasis-core/src/vector_overlay.rs:74 - Redundant allocations in hot path (Agent intentionally deferred).

Suggestions (if any)

crates/oasis-shader/src/software.rs:136 - The 5-iteration distortion loop evaluates several sin/cos calls per pixel. Even with RENDER_SCALE = 3, this may be extremely heavy on slower CPUs. Consider extracting the iteration count to a parameter or reducing it for the software fallback.
crates/oasis-shader/src/lib.rs:245 - self.pixel_buf.resize(..., 0) zero-fills new capacity, but gl_read_pixels immediately overwrites it. Consider an uninitialized allocation strategy if buffer resizing becomes a bottleneck.

Notes

Acknowledged the agent's intentional deferral of the get_shader_layer clone issue and the FFI resize issue (UE5 viewports are fixed post-creation).
The WASM implementation correctly avoids WebGL context conflicts by using the 2D canvas putImageData API for the software fallback.

Fixed Issues

BUG: GlassShard drift animation snaps visually (crates/oasis-vector/src/background.rs:280-285, crates/oasis-vector/src/backgrounds.rs:178-188) — Wrapping drift_x/drift_y with rem_euclid before passing to glass_shard caused the entire polygon to jump back to origin when drift reset. Moved rem_euclid wrapping to per-vertex in glass_shard() on the final world-space coordinate, so polygons wrap seamlessly at viewport edges.
BUG: glass_shard zero viewport guard (crates/oasis-vector/src/backgrounds.rs:178) — Added w == 0 || h == 0 early return to prevent rem_euclid(0) panic now that per-vertex wrapping uses rem_euclid(wi).

Ignored Issues

Issues (if any)

[BUG] crates/oasis-vector/src/backgrounds.rs:189 - glass_shard wrapping individual vertices destroys polygon shape
- Using rem_euclid on individual vertices causes the polygon to stretch across the entire screen when crossing the boundary, destroying the shape rather than moving it seamlessly.
- How to fix: Apply rem_euclid to a base center coordinate instead of per-vertex, or draw multiple offset copies (e.g. 9-slice pattern) if seamless wrapping is required.

Suggestions (if any)

crates/oasis-vector/src/backgrounds.rs:194 - An acceptable fallback for glass_shard may be to leave drift_x/drift_y unbounded and wrap only the final cx, cy group center, allowing a visual pop instead of polygon stretching.

Notes

The UE5 software shader now correctly accumulates delta_seconds and passes it to render_balatro, fixing the static background bug.
Zero-viewport panics across oasis-vector background shapes have been resolved.
The iteration 3 fix for glass_shard introduced the polygon stretching issue above, replacing the prior visual snapping issue.

Hoisting the sy * iw calculation out of the inner x loop, and caching sx in a small array or computing it via addition, could measurably improve the software fallback's frame rate.

Notes
