#hlsl — Public Fediverse posts

Can any #shader guru explain why the first statement gives weird artifacts, and the second one doesn't? Why are they not equivalent?

lut_index_a is indirectly derived from a varying float that comes in from the vertex shader.

The artifacts seem to be occurring in 8x8 pixel blocks which are tied to the viewport, not the geometry.

Using an AMD Radeon RX 7600 on Arch Linux, I think with the Mesa driver.

Рендеринг миллионов динамических связей: O(1) вместо O(N²) (но это не точно)

Привет, Хабр! В предыдущей публикации про рендеринг космического окружения в игре The 13th Sign, я обещал рассказать про то, как мы рисуем частицами персонажей. Задача уже решена и статья скоро будет, но в процессе разработки я наткнулся на кое-что не менее интересное. Под катом, конечно же, трюк – бесплатных пирожных в математике не бывает.

The Khronos Group is running a survey on the broader shader ecosystem — languages, tools, pain points, and where standardization is needed most. If you write shading code in any language (Slang, HLSL, GLSL, WGSL, etc.), your input helps shape where Khronos focuses next.

Results will be shared at the SIGGRAPH Real-Time Shading BOF this year.

Deadline: July 10

Take the survey: https://www.surveymonkey.com/r/LKWFQ3M

It's anonymous and only takes a few minutes.

Идеальный Outline в Unity 6: Пишем эффект обводки под новый URP Render Graph

Если вы недавно обновились до Unity 6 (или URP 17+) и попытались перенести свои старые пост-эффекты, то наверняка столкнулись с красной консолью и предупреждениями об устаревших методах. Старые туториалы по созданию эффекта обводки (Outline) через ScriptableRendererFeature больше не работают "из коробки". Unity полностью изменила архитектуру рендера, внедрив Render Graph . Старый добрый метод Execute канул в Лету, а fullscreenMesh заменили на Blitter . В этой статье мы не просто перепишем классический эффект Outline под новые реалии Unity 6. Мы решим две главные проблемы подобных шейдеров, о которых часто умалчивают в гайдах.

Sooo, I want to sample mipmaps in a compute shader via "sampleGrad".

Does anyone know what the state-of-the-art is for deriving ddx and ddy for uv-coords in a compute shader?

I don't want to store the UV's derivatives in a G-buffer if possible.

Oriol Engine: как мы решили проблему кросс-компиляции шейдеров

${habrauser} , Привет! При разработке игрового фреймворка Oriol Engine (которая, к слову, до сих пор ведётся) мы столкнулись с проблемой написания шейдеров для Cross-API рендеринга. В RHI-слой данного фреймворка было запланировано добавить поддержку таких графических API , как DX11/DX12 , OpenGL и Vulkan . И вот тут возникает вопрос: как же писать шейдеры на одном языке и обеспечить их поддержку на других графических API ?

Khronos announced the inaugural Shading Languages Symposium, that will take place on February 12-13, 2026, in San Diego, California. The symposium will bring together developers, implementors, researchers, and technical artists to explore the current state and future development of #shading languages and real-time #rendering technologies. The open call for submissions for the symposium closes on October 12, 2025.
