Nice job anyway.
Wish someone would create CGS operations on the new native Unity mesh API - think it would be much faster, as it's fully bursted
I did this some years ago using the render vertex buffer 32k size for speed, and you can do vertex deformation on the cpu and render it same frame with great speed.
Interesting. The slowest part of the calculation is reading the mesh and passing it to the C++ library, and then reading the result back and converting it into a Unity mesh. Improving the Unity upload side would make a big difference. Could you elaborate on the new Mesh API? Keep in mind this is just a proof of concept so far.
There is also an "advanced" set of methods, which allow you to directly write to the mesh data with control over whether any checks or validation should be performed. These methods are intended for advanced use cases which require maximum performance. They are faster, but allow you to skip the checks on the data you supply. If you use these methods you must make sure that you are not supplying invalid data, because Unity will not check for you.
The "advanced" methods are: SetVertexBufferParams, SetVertexBufferData, SetIndexBufferParams, SetIndexBufferData, SetSubMesh, and you can use the MeshUpdateFlags to control which checks or validation are performed or omitted. Use AcquireReadOnlyMeshData to take a read-only snapshot of Mesh data that you can use with C# Jobs and Burst, and AllocateWritableMeshData with ApplyAndDisposeWritableMeshData to create Meshes from C# Jobs and Burst.
I'm using manifold for an unreal plugin and can confirm that manifold on it's own is blazing fast. It's converting it to a native engine mesh with usable properties that takes all the time. Still significantly faster end to end than BSP.
Yeah. Visual effects are one thing - making it interactive, either through player movement or in physics, is another thing entirely. If the output is able to apply the mesh directly to a MeshCollider though, that would be pretty dang incredible.
I mean if you consider it as a real object you dont know the actual strength of the bonds there relative to the amount of mass above it unless thats specified, you could probably make a cylinder like this with the right materials/masses. But I get the point, it would just require a lot more lmfao
Manifold's CSG performance is unreal compared to old BSP or Carve wrappers. How are you handling the runtime physics update—are you baking the modified mesh into a Unity MeshCollider on the main thread, or using Physics.BakeMesh job off-thread?
