Description

Kostas Anagnostou's technical blog on graphics programming experiments and production-adjacent notes. Anagnostou is a lead rendering engineer (formerly at Playground Games on Fable) who uses the site as a scratchpad for techniques he tries outside day-job constraints.

Posts explore hybrid ray-traced shadows and reflections, order-independent transparency (linked lists, per-pixel layers, transmittance functions), image-based lighting occlusion and directionality, shader ISA and micro-optimization tips, API abstraction, and recent neural rendering explorations including MLP signal encoding with DirectX cooperative vectors.

Writing mixes HLSL snippets, performance observations, and honest assessments of when ray tracing complements rather than replaces rasterization. Multi-part series dive deeply into OIT and IBL implementation details with reference images.

Articles are free on WordPress with an RSS feed and social links. The audience is experienced graphics programmers comfortable reading engine-level shader and architecture discussions.

Known among advanced rendering developers for thoughtful production-grade experiments; frequently shared when developers discuss hybrid RT, OIT, or IBL directionality beyond stock engine features.
