DetDgfx

detDgfx is a term used in technical discussions to denote a compact, deterministic digital graphics format and its reference implementation. It is described as a container for vector primitives, materials, transformations, and scene metadata designed to produce bit-for-bit identical output across platforms when provided with the same inputs and environment.

The format organizes data in a binary, chunked layout. A header carries a magic identifier, version, and endianness, followed by a sequence of chunks for scene graph nodes, attributes, and shader instructions. Each node includes a local transform, a material reference, and optional procedural parameters. Shaders are represented in a sandboxed form with a fixed set of operations to ensure portability and determinism. A scene-level random seed and explicit rounding rules aim to eliminate variance from stochastic elements.

DetDgfx supports optional lossless compression and streaming access, enabling archival of render results and progressive decoding for offline or real-time workflows. Determinism is achieved through defined numerical precision, deterministic sampling, and careful handling of floating-point arithmetic across platforms.

Usage and status: detDgfx has seen limited adoption and is primarily discussed in research and experimental tooling. Proponents emphasize reproducibility for scientific visualization, rendering experiments, and cross-compiler interchange. Critics point to limited tooling, evolving specifications, and compatibility challenges with established formats.
