base on Optimizes mesh and polygon colliders in Unity # Unity Collider Optimizer Optimizes Mesh & Polygon colliders in Unity.  ## Polygon Collider Optimizer |  |  |  | |:---:|:---:|:---:| | Original Sprite | Unity Polygon Collider | Optimized Polygon Collider | |**Path Count**| *213 paths* | *23 paths* | The tool uses a [C# implementation](https://www.codeproject.com/Articles/18936/A-C-Implementation-of-Douglas-Peucker-Line-Appro) of the Ramer Douglas Peucker Algorithm to smooth the polylines and reduce the number of paths created by a Polygon Collider in Unity. #### Performance Comparison https://github.com/aniketrajnish/Unity-Collider-Optimizer/assets/58925008/e134f0c6-4c08-4552-b69f-22e7f3b61ebe You can run this test on your machine by cloning the project and going to the `Polygon Collider Optimization Test` scene in Unity. #### Usage * Download the `collideroptimizationpackage_2d_v004.unitypackage` package from the [Releases](https://github.com/aniketrajnish/Unity-Collider-Optimizer/releases/). * Import all the assets from the package in your unity project. * Attach the `PolygonColliderOptimizer.cs` script on your 2D sprite. * Adjust the `optimizationFactor` to control the amount of optimzation you need. https://github.com/aniketrajnish/Unity-Collider-Optimizer/assets/58925008/74f5bdd1-f5c8-4c44-b745-78211919aae3 ## Mesh Collider Optimizer |  |  |  | |:---:|:---:|:---:| | Original Mesh | Unity Mesh Collider | Optimized Mesh Collider | |**Triangles Count**| *9132 tris* | *2416 tris* | The tool uses the [Computational Geometry Unity Library](https://github.com/Habrador/Computational-geometry) by Erik Nordeus 🐐 to perfrom the Quadric Error Metrics simplification on the shared mesh of the mesh collider. #### Performance Comparison https://github.com/aniketrajnish/Unity-Collider-Optimizer/assets/58925008/cfba7837-a81e-4891-9594-501fbf31680f You can run this test on your machine by cloning the project and going to the `Mesh Collider Optimization Test` scene in Unity. #### Usage * Download the `collideroptimizationpackage_3d_v004.unitypackage` package from the [Releases](https://github.com/aniketrajnish/Unity-Collider-Optimizer/releases/). * Import all the assets from the package in your unity project. * Attach the `MeshColliderOptimizer.cs` script on your 2D sprite. * Choose the connecting mode between _Fast, Precise, and No._ * Adjust the `optimizationFactor` to control the amount of optimzation you need. * Choose the mesh style to be _Soft, Hard or both_. * **Warning: Choosing the "Fast" mode would likely lead to errors, Precise mode is recommended for most of the meshes.** https://github.com/aniketrajnish/Unity-Collider-Optimizer/assets/58925008/ddb08b48-d241-494c-a6f4-0a822424964a ## Updates #### v004 * Added the functionality to save and load the optimized colliders as assets. * Fixed the refresh bug. https://github.com/aniketrajnish/Unity-Collider-Optimizer/assets/58925008/ba42c61c-4ea1-419d-bf81-324304a218b8 ## Contribution Contributions to the project are welcome. Currently working on converting the QEM algorithm to a coroutine to stop the main Unity thread from freezing. ## Known Bugs * ~~If a prefab is made out of a gameobject having Polygon Collider Optimizer, it keeps refreshing itself.~~ **[FIXED]** * Choosing Hard Edge Mesh Style decreases the number of triangles but induces additional vertices (doesn't affect the performance). ## License MIT License ", Assign "at most 3 tags" to the expected json: {"id":"3238","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
