The Case for Graphics Programming Using the D Language

on YouTube ↗01h 22m

" summary

Examples include a D-written ray tracer from "Ray Tracing in One Weekend" that compiles and renders images, shaders embedded as source, and an OBJ parser built with ranges and slicing; the build uses DMD (LDC/GDC for speed) plus OpenGL and GLFW. Compile-time tricks like compile-time function execution and mixins generate zero-branch math; a parallel foreach cuts a render from 5.9s to 0.76s, and switching a heap-allocated class to a struct roughly halves runtime. Unit tests, profiler and optional GC/betterC control are used.
