From fca95ad07e80e26b91b74b27667afb09c3addbbd Mon Sep 17 00:00:00 2001 From: bymyself Date: Sun, 14 Sep 2025 18:09:46 -0700 Subject: [PATCH] [perf] Remove legacy Float32Array usage from LiteGraph Removes Float32Array usage throughout LiteGraph codebase, eliminating type conversion overhead for Canvas 2D rendering operations. ## Changes Made ### Core Data Structures - **LGraphNode**: Convert position/size arrays from Float32Array to regular arrays - **LLink**: Convert coordinate storage from Float32Array to regular arrays - **Reroute**: Replace malloc pattern with standard properties - **LGraphGroup**: Convert boundary arrays from Float32Array to regular arrays ### Rendering Optimizations - **LGraphCanvas**: Convert static rendering buffers to regular arrays - **Drawing Functions**: Replace .set() method calls with direct array assignment - **Measurement**: Update bounds calculation to use regular arrays ### Type System Updates - **Interfaces**: Update Point/Size/Rect types to support both regular arrays and typed arrays - **API Compatibility**: Maintain all existing property names and method signatures ## Performance Benefits - Eliminates Float32Array conversion overhead in Canvas 2D operations - Reduces memory allocation complexity (removed malloc patterns) - Improves TypeScript integration with native array support - Maintains full API compatibility with zero breaking changes ## Background Float32Array usage was originally designed for WebGL integration, but the current Canvas 2D rendering pipeline doesn't use WebGL, making the typed arrays an unnecessary performance overhead. Every Canvas 2D operation that reads coordinates from Float32Array incurs type conversion costs. --- src/lib/litegraph/src/LGraphCanvas.ts | 30 ++++++++++++------- src/lib/litegraph/src/LGraphGroup.ts | 29 ++++++++++-------- src/lib/litegraph/src/LGraphNode.ts | 21 +++++++------ src/lib/litegraph/src/LLink.ts | 4 +-- src/lib/litegraph/src/Reroute.ts | 8 ++--- src/lib/litegraph/src/interfaces.ts | 19 +++++++++--- src/lib/litegraph/src/measure.ts | 7 ++++- .../src/subgraph/SubgraphSlotBase.ts | 2 +- 8 files changed, 76 insertions(+), 44 deletions(-) diff --git a/src/lib/litegraph/src/LGraphCanvas.ts b/src/lib/litegraph/src/LGraphCanvas.ts index 83ce47660..3c59b2773 100644 --- a/src/lib/litegraph/src/LGraphCanvas.ts +++ b/src/lib/litegraph/src/LGraphCanvas.ts @@ -236,11 +236,11 @@ export class LGraphCanvas implements CustomEventDispatcher { // Optimised buffers used during rendering -
