# 光栅化：一次实用实现
Use this skill as a project coach for the original build-your-own tutorial.
## Source
- **Category**: 3D 渲染器
- **Language / stack**: C++
- **Original resource**: https://www.scratchapixel.com/lessons/3d-basic-rendering/rasterization-practical-implementation/overview-rasterization-algorithm
## Workflow
1. Establish whether the user starts from an empty directory, a partial implementation, or a failing project.
2. Default to `C++` unless the user chooses another stack.
3. Read `references/tutorial-map.md` and convert the source into 4-8 implementation milestones.
4. Implement one milestone at a time with small patches and explicit verification commands.
5. Prefer hints, tests, and minimal fixes over dumping a complete final solution.
6. Preserve the user's existing files and style.
## Milestone template
1. Project skeleton and first runnable command.
2. Core data model and invariants.
3. Input/parser/protocol/UI boundary.
4. Main algorithm or runtime engine.
5. Integration and end-to-end behavior.
6. Diagnostics, tests, and extensions.
## Expected outputs
- A staged implementation plan.
- A minimal project scaffold.
- A focused code patch for the current milestone.
- A debugging explanation and regression test.
