mesh shaders

A Remedy engineer explains how Alan Wake 2 moved to a GPU-driven rendering pipeline built on mesh shaders, culling and rendering meshlets for dense vegetation on PS5 and Xbox Series consoles.

John Oliver's Last Week Tonight segment on timeshares covers how people get sold into them, why they are so hard to leave, and the exit-company scams that target owners trying to get out.

Emery Berger's CppCon 2019 talk introducing Mesh, a drop-in malloc replacement that compacts memory in unmodified C and C++ programs. It tackles fragmentation by merging pages without changing pointers.

The first part of Freya Holmer's three-part, nearly four-hour lecture on shader coding for game devs in Unity. It covers what shaders are, vertex and fragment shaders, interpolators, data types, blending and textures.

Peter Pringle sings the opening of the Epic of Gilgamesh in Sumerian, accompanied by a reconstructed ancient instrument. The description gives background on Sumer, cuneiform and how little is known about the language's pronunciation.

Sebastian Lague explores an ant-inspired algorithm and simulates ant and slime mold behavior, using compute shaders. Source code for both simulations is available.

Joe Armstrong, creator of Erlang, and Jeremy Ruston, creator of TiddlyWiki, discuss hypertext, Ted Nelson's idea of intertwingled knowledge, and a way to combine TiddlyWiki with Erlang. It is a Code Mesh LDN 2018 talk.

Ramesh Raskar presents femto-photography, a technique that captures a trillion frames per second, fast enough to show light itself moving through a scene. He discusses possible uses such as cameras that see around corners or inside the body.

Acerola explores building a shader that turns games into ASCII art, walking through techniques such as brightness mapping and edge detection to see whether it looks good.

Edwin Brady presents Idris 2, a rewrite of the Idris dependently typed language, and shows type-driven development in practice. The demos show the compiler filling in whole functions from their types.

Noodle explores how retro pixel art was designed for CRT displays and why games look different on LCDs, with input from pixel artists and CRT researchers.

Bobby Powers presents Mesh, a drop-in malloc replacement that eliminates memory fragmentation in unmodified C/C++ programs by compacting memory. The talk covers how it works despite C's fixed object addresses, and its benefits for programs like Redis.

Inigo Quilez shows step by step how to build a simple heart shape from mathematics and shaders, with code on Shadertoy. It is an introduction to procedural graphics and signed distance functions.

A one-minute demo comparing RetroArch shaders on the Sonic the Hedgehog waterfall, where Sega Genesis dithering creates a transparency effect. It shows how different shaders emulate the CRT look.

Inigo Quilez live-codes a cartoon character painting entirely from math, using signed distance fields in a Shadertoy shader. He explains each step of building the image from formulas.

Inigo Quilez live-paints a mountain landscape using only math in a shader, building up from a basic polynomial noise surface through fractal terrain, lighting and atmosphere. The code runs in real time on Shadertoy so viewers can edit it as they follow along.

Intrinsic Gravity is a real-time demoscene production by Still, made with the Tooll tool for Under Construction 2014. It is a black-and-white op-art animation with a soundtrack by hoffman.

Rune Skovbo Johansen explains Surface-Stable Fractal Dithering, a technique he invented and released as open source. It makes dithering stick to 3D surfaces and covers the experiments and shortcomings along the way, inspired by Return of the Obra Dinn.

Johann Korndorfer's NVScene 2015 talk on building content with signed distance functions. It focuses on patterns that make SDF modelling more structured, arguing that SDFs capture a shape's essence like vector graphics do compared with polygons or voxels.

Inigo Quilez live-codes the "Happy Jumping" animated scene in a Shadertoy GLSL shader over about six hours. He builds the raymarched character step by step, explaining the math and procedural techniques, with checkpoints linked for each stage.

Cloth Map documents Havana's SNET, a community-built private network that Cubans created because internet prices were high. It is used for gaming and sharing.

A short clip from HBO's Silicon Valley in which a focus group savages a product by calling it as bad as Apple Maps. It satirizes tech product launches.

Brian Karis's SIGGRAPH 2021 talk explains how Unreal Engine 5's Nanite virtualized geometry works. It covers mesh import, the data structures, streaming, decompression, culling, software and hardware rasterization, and shading.

Joe Armstrong, creator of Erlang, interviews Alan Kay at Code Mesh. They discuss the meaning of object orientation, message passing, the META II paper, and the state of computer science.

Brian Troutwine's Code Mesh 2015 talk on the Apollo Guidance Computer. It covers the AGC's design, core rope memory, its interrupt and software behavior, and the pioneering engineering effort behind it.

Lex Fridman interviews Brian Kernighan, co-author of The C Programming Language and co-creator of AWK and AMPL. They discuss Unix, C, Go and his memoir on the history of Unix.
