Could you build this?
No Building a 3D software renderer in C from scratch with zero third-party libraries requires deep low-level computer graphics math, rasterization algorithms, clipping, and memory management.
What it would actually take: The architecture requires pure C with custom linear algebra routines (matrix/vector math, quaternions, perspective projection), custom triangle rasterizers, depth-buffering (z-buffer), and manual frame/color buffer output (e.g., raw PPM/BMP or bare OS windowing framebuffers). The hard parts are writing efficient sub-pixel triangle rasterization, perspective-correct barycentric interpolation, clipping algorithms (Sutherland-Hodgman), and lighting shaders without GPU acceleration or external math libraries. This requires a graphics programmer with deep foundations in computer graphics theory and low-level C systems programming.
