From 58445e769955575e562d6738333c1f75fc805f0e Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 30 Jan 2026 19:59:47 +0000 Subject: [PATCH 1/2] fix: Deep copy TypedArrays in geometry cloning to prevent WebGPU buffer sharing The previous fix using geometry.clone() + needsUpdate still allowed internal buffer references to be shared between source and cloned geometry. When the source geometry was disposed, the shared GPU buffer references became invalid. This fix creates completely fresh TypedArrays using array.slice(0) for all attributes and index buffers, ensuring zero shared state with the source geometry. This prevents "setIndexBuffer" crashes even when source geometry is disposed while clones are still being rendered. Changes: - UnitRenderer: Deep copy all attributes and index - ResourceRenderer: Deep copy all attributes and index - BuildingRenderer: Deep copy all attributes and index - InstancedDecorations: Deep copy all attributes and index - GPUIndirectRenderer: Deep copy all attributes and index Also copies morph attributes, bounding volumes, and groups for completeness. https://claude.ai/code/session_01RVGDnXRzL5S5tELbcBqYrN --- src/rendering/BuildingRenderer.ts | 57 ++++++++++++++++---- src/rendering/InstancedDecorations.ts | 57 ++++++++++++++++---- src/rendering/ResourceRenderer.ts | 57 ++++++++++++++++---- src/rendering/UnitRenderer.ts | 57 ++++++++++++++++---- src/rendering/compute/GPUIndirectRenderer.ts | 54 ++++++++++++++----- 5 files changed, 225 insertions(+), 57 deletions(-) diff --git a/src/rendering/BuildingRenderer.ts b/src/rendering/BuildingRenderer.ts index d0e8e075..014bad73 100644 --- a/src/rendering/BuildingRenderer.ts +++ b/src/rendering/BuildingRenderer.ts @@ -103,23 +103,58 @@ const MAX_BUILDING_INSTANCES_PER_TYPE = BUILDING_RENDERER.MAX_INSTANCES_PER_TYPE const MAX_SELECTION_RING_INSTANCES = BUILDING_RENDERER.MAX_SELECTION_RING_INSTANCES; /** - * Clone geometry with proper GPU buffer initialization for WebGPU. - * Setting needsUpdate on cloned attributes forces WebGPU to create fresh GPU buffers. - * Without this, WebGPU may lazily share buffers with the source geometry, which - * become invalid when the source is disposed, causing "setIndexBuffer" crashes. + * Clone geometry with completely fresh GPU buffers for WebGPU. + * Creates new TypedArrays for all attributes and index to ensure zero shared state + * with the source geometry.
