Walkthrough

This change updates the _drawMask method in the RenderQueue class. It adds functionality by declaring a new constant, primitiveChunkManagerMask, from the engine’s batcher manager. After processing the increment and decrement mask queues, the _drawMask method now calls uploadBuffer() on the primitive chunk manager mask to ensure that the buffer is updated. The structure of the class remains unchanged and no public entities were modified.

Changes

File Change Summary
packages/.../RenderQueue.ts In _drawMask: declared primitiveChunkManagerMask from engine._batcherManager and added calls to primitiveChunkManagerMask.uploadBuffer() after both the increment and decrement mask queue processes.

Poem

I'm a bunny on a code-high hop,
Watching mask uploads never stop.
Increment and decrement, buffers in flight,
My tiny paws write code just right.
Hop along the RenderQueue delight!

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

215-221: LGTM! Important fix for mask buffer synchronization.

The changes correctly ensure that mask buffer data is synchronized with the GPU after batching operations. This fixes the mask chunk upload bug by adding necessary buffer uploads at the appropriate points in the rendering pipeline.

The fix follows good rendering pipeline practices by maintaining proper synchronization between CPU-side changes and GPU-side buffers. This is crucial for ensuring that mask operations are correctly applied during rendering.
