digitalmars.D.announce - D and C++ renderer side by side demonstration

I was watching Timur Gafarov’s videos on Dagon Engine and 
stumbled upon a video that demonstrated a C++ Renderer Engine 
using the same Sponza scene. I thought it would be a great idea 
to show them side by side.

This is not a “X vs Y” video! It just demonstrates the 
capabilities of D and C++ side by side.

Sorry, but it just demonstrates the capabilities of 2 seemingly 
totally unrelated rendering engines and might easily mislead 
beginners, not helping D at all. What makes you think the used 
programming language would have any effect on the capabilities of 
a rendering engine? Some old Quake engine was ported from C or 
C++ to Emscripten (JavaScript) via WebGL by Carmack himself IIRC 
some years ago, and the visual results were unsurprisingly 
identical. There might be differences in efficiency, especially 
for JavaScript vs. a system programming language, but most modern 
graphics are GPU-bound anyway.

Relax, not sure where you are drawing this conclusion from. You 
probably are overthinking this. Any content that shows what D can 
do or mentions D is a plus IMO.

You can do rendering engines in D, nice example. Next questions 
would be

1. Is GC being used or is custom memory management being used?
2. How much is D and how much are library calls (to OpenGl, 
DirectX whatever which presumably are done in C++)?
