Hi folks, I'm working on a Tile based Deferred renderer, similar to this Apple example. I'm wondering how to add MSAA to the renderer, and I see two choices: Copy the single-sampled texture at the end of the GBuffer/Lighting render pass to a multi-sampled texture and resolve from that Make all render targets (GBuffer) multi-sampled and deal with sampling/resolving all intermediate textures as well as the final, combined texture. Which is the proper approach, and are there any examples of how to implement it? Thanks!

I'm using the Apple RoomPlan sdk to generate a .usdz file, which works fine, and gives me a 3D scan of my room. But when I try to use Model I/O's MDLAsset to convert that output into an .obj file, it comes out as a completely flat model shaped like a rectangle. Here is my Swift code: let destinationURL = destinationFolderURL.appending(path: "Room.usdz") do { try FileManager.default.createDirectory(at: destinationFolderURL, withIntermediateDirectories: true) try finalResults?.export(to: destinationURL, exportOptions: .model) let newUsdz = destinationURL; let asset = MDLAsset(url: newUsdz); let obj = destinationFolderURL.appending(path: "Room.obj") try asset.export(to: obj) } Not sure what's wrong here. According to MDLAsset documentation, .obj is a supported format and exporting from .usdz to the other formats like .stl and .ply works fine and retains the original 3D shape. Some things I've tried: changing "exportOptions" to parametric, mesh, or model. simply changing the file extension of "destinationURL" (throws error)

Guten Tag, my project is simple, first I want draw wired Hexa,-Tetra- and Octahedrons. I draw a cube with Metal but I didn't found rotation, translation and scale. I have searched help , the examples I found are too complicated for me. Mit freundlichen Grüßen VanceRegnet
