3D Software Renderer, using Xcode to develop

3D Graphics Programming from scratch

This is my learning process of Pikuma's 3D Graphics From Scratch course. ($69.99)

Using only SDL2 and a C compiler. No Graphics API, no GPU, no OpenGL, no Metal, no DirectX!

Implement a software-renderer from scratch, draw every pixel on the screen to render a 3D obj model file.

How to build & run

Xcode press Run button

Development environment: using Xcode.

"Setting up SDL 2 on XCode 13.4.1"

SDL 2 and Xcode trouble shootings:

I cannot build and run, dyld cannot find suitable dynamic library at runtime

• Third-Party framework need to be code signed before running, a strict restriction enforced by Xcode and macOS recently.

• Project settings -> General -> Frameworks and Libraries, SDL2.framework, change 'Embed' from 'Do Not Embed' to 'Embed and Sign'

Why there are no autocomplete or Intellisence, and "cannot find SDL2.h" error?

• you have to clean after every build, see "Weird Problem with XCode, SDL2, and Catalina"

• Press cmd+option+k to clean the project, after every cmd+r

How to set working directory, so program can access the assets folder to fetch images or 3D obj files?
