Unity submeshdescriptor. 9f1です。 まず、C#のスクリプトです。 MeshFilter からメッシュを取得して参照用のメッシュ originalMesh と変更用のメッシュ displacedMesh をそれぞれ作成します。. SetSubMesh So loop for each submesh in your original, creating new meshes that contain only the data required by that mesh. 4k次。本文介绍如何在Unity3D中使用高级API创建带有多种材质的Mesh，并通过划分SubMesh实现不同材质区域的渲染。文章详细展示了创建Mesh、设置顶点属性、使用SubMeshDescriptor划分子Mesh的过程。 "Unity"、Unity 徽标及其他 Unity 商标是 Unity Technologies 或其附属机构在美国及其他地区的商标或注册商标。其他名称或品牌是其各自所有者的商标。 Aug 28, 2022 · The SubMeshDescriptor that is passed into the Mesh. 概述 在文章Unity3D学习笔记4——创建Mesh高级接口通过高级API的方式创建了一个Mesh，里面还提到了一个SubMesh的概念。Mesh是对于三维物体对象的封装概念，一个很容易的需求是，有的地方我希望用到材质A，有的地方我希望用到材质B，我不想把这个Mesh进行拆分，那么很简单，就在 Note that SetSubMesh, SubMeshDescriptor, and SetIndexBufferData are designed for advanced users aiming for maximum performance, because they operate on the underlying mesh data structures that primarily work on raw index buffers, vertex buffers and mesh subset data. Using these methods, Unity performs very little data validation, so you must ensure your data is valid. SetSubMesh, Mesh. However, I am using this function along with a compute shader writing Jul 3, 2022 · 1. DontRecalculateBounds flag is passed. SetIndexBufferParams, and Mesh. Declaration public SubMeshDescriptor (int indexStart, int indexCount, MeshTopology topology); Jul 3, 2022 · 文章浏览阅读1. SetIndexBufferData. Simple usage of Mesh scripting API involves using functions like Mesh. This advanced API gives access to the underlying mesh data structures that primarily work on raw index Apr 18, 2024 · Each submesh has a SubMeshDescriptor, which consists of identifying the first triangle of that submesh, the number of triangles in that submesh, and some other data. I want to then extract one mesh from these uber-arrays, so I’m using SubMeshDescriptor. Unity - Scripting API: Mesh. Thing is, despite the extracted mesh having correct triangle indices, I get this error: This is the code I’m using: mesh The SubMeshDescriptor-bounds, SubMeshDescriptor-firstVertex and SubMeshDescriptor-vertexCount values of SubMeshDescriptor are calculated automatically by SetSubMeshes, unless MeshUpdateFlags. baseVertex with a negative value to offset the indices in the triangles array. 2. vertices and so on. Note that SetSubMesh, SubMeshDescriptor, and SetIndexBufferData are designed for advanced users aiming for maximum performance, because they operate on the underlying mesh data structures that primarily work on raw index buffers, vertex buffers and mesh subset data. firstVertex These values are important for any CPU-based mesh processing that would be done, for example dynamic batching or CPU skinning. For advanced use cases that require maximum performance, you can use the advanced API, which has functions like Mesh. MeshUpdateFlags. May 23, 2023 · Hi! I’ve got a triangles and a vertices array, result of combining multiple meshes together. In particular, you must Sep 1, 2022 · Unity - Scripting API: Rendering. DontRecalculateBounds is also passed as an argument as well. Mar 3, 2022 · 結果はこのようになります。 検証で使用しているUnityのバージョンは2021. I assume that the vertexCount is still calculated from the index buffer. SubMeshDescriptor. In particular, you must Nov 6, 2023 · You can also read about that in the documentation: Note that SetSubMesh, SubMeshDescriptor, and SetIndexBufferData are designed for advanced users aiming for maximum performance, because they operate on the underlying mesh data structures that primarily work on raw index buffers, vertex buffers and mesh subset data. Note that this only applies to the bounds of the SubMesh. triangles, Mesh. SetSubMeshes has a vertexCount, but this field is changed to something else when accessing after the function is called. moaxahdv3wpot881gmb1euk9c8dadq3kwoj7ce0tgbf4efernuhoxndhy1deqclhvxrw2xrflowgcsrlq9ddboitg2qfdhlbhqnrukoil4t
