I have a quad made up of two triangles rendered using indexed primitives. How can I create a transform where only one corner of the quad is stretched, like the perspective tool in most drawing apps?
For example:
If I want to use SF Symbols 3 in my swift project, do I have to export the symbols from the SF Symbols app and add them to my app's Asset Catalog, or is there a way for Xcode to automatically use those symbols without me having to add them to the Asset Catalog?
