You need to build a system three times

• the first time you don't know what you actually need, it's an exploration, plan to throw it away
• the second time you think you know what you need so you over-architect, it'll be too restrictive, plan to throw it away
• the third time you build what actually works

I like to think I came up with it at LucasArts twenty years ago, but at this point I don't know if it was generally in the zeitgeist.

class PBRMesh {
    var mtkMesh : MTKMesh?

    var submeshes = [PBRSubmesh?]()
    // create an array with 3 entries initialized to nil
    //   swift doesn't have fixed size object arrays
    var pipeline = [PBRModel_Pipeline?](repeating: nil, count: 3)

property

face count, integer

the number of faces in a mesh

property

face topology, array of 8 bit unsigned integers

each entry at index i corresponds to face i the value of the entry is the arity of the face; i.e. a triangle is 3 and a quad is 4

Windows tooling

Windows c/c++ tooling (in general) causes unnecessary pain, from dllimport/export to debug vs release crt we can establish expected practices eg aswf projects have a common pattern on how to do the adornment we can try to engage microsoft i understand they won't listen or respond in general we can explore solutions. We could bypass the CRT entirely by investigating a move to musl. There are many possibilities.

build systems

build systems as commonly practiced are slow
