Also modern C++ has constructs such as templates and ranges, which are not simple 1:1 operations. The language has constructs that are inherently slow to compile. Many of them could be designed slightly differently and/or by making them language features instead of library features to make them significantly faster to compile. C++20 std library headers for example are significantly slower to compile vs C++17. Language isn't slower to compile, but the standard library is. It's such a massive template clusterfuck. So it's not just a compiler problem, it's also a standard library problem.

Local lights are now live in HypeHype! 🎉
I developed a new stochastic lighting algorithm — from concept to prototype to production — in just 6 months. Super proud of this one! [Details in thread 🧵]
Here's a walkthrough of a game I relit with local lights

meshoptimizer 0.23 is out! Featuring vertex codec v1 (increased compression ratio, faster decompression), even faster decompression on Apple Silicon, improvements to meshlet builder with fewer disconnected clusters and more options for clustered raytracing and hierarchical clusterization, new algorithms for hierarchical clusterization, simplification quality improvements and more.
Thanks to Valve for sponsoring most of the work on the core library in this release!

Introducing Glove Sculpts.
Created from high-quality 3D scans, carefully cleaned, retopologized, and precision-sculpted to ensure exceptional detail. This library includes tactical, work, casual, winter, sports, and more glove styles. triplegangers.com
These models are perfect for adding realistic detail to your characters.
Glove Sculpts collection features 10 tactical, 6 sport, 19 casual and 30 work gloves, varying in their use case.
Glove Sculpts are delivered as:
- Zbrush *.ztl format file (Subtool) with an average of 7 subdivision levels.
- 8192x8192 pixels uncompressed *.tif texture in Linear Color.
- 4096x4096 specular map.

Tiny Glade's rendering started simple, but now we have real-time global illumination, GPU-driven rendering, novel DoF, ray tracing, and entirely too much ray marching :D
Wanna know more? Come see my GPC talk!

Performance comes from architecture. It’s not a thing you can bolt on at the last minute. It dies by a thousand small cuts, and thats not something you can fix a month before shipping. We’re no longer in the age of Icer Addis commenting out a PS2 syscall to get Madden to 16.666ms

Daily #Blender Tip: With this technique you can even use a mouse to draw perfectly tapered curves, creating ornament details easily. Last day to take advantage of my summer sale!

Quick and dirty, low accuracy approximation to elementary functions, new-ish from J.Muller (who wrote the book on elementary functions). Bipartite tables, bit tricks for logs and simple approximations of Sin and Cos without range reduction.

Famously, you can turn any mesh into a "nice" (Delaunay) triangulation by just greedily flipping edges.
We show that you can likewise turn any path into a straight (geodesic) path… by just greedily flipping edges!
Even works on curved surfaces:

Finding geodesics on triangle meshes is a classically tricky problem. In new work with @keenanisalive at SIGGRAPH Asia, we discovered that a simple policy of greedily flipping edges provably generates a geodesic path! (1/N)

You know what, IDE, I think you've kind of missed the point here.
