drilla

Drilla engine for HPC and visualization

develop

requirements:

• Node.js and pnpm
• dotnet 8.0

run dev environment

onetime

• Deprecated Add DUALDRILLFFMPEGPATH environment variable, value should be bin folder of ffmpeg (with shared libraries) directory. On windows, it could be installed using winget install "FFmpeg (Shared)" --version "6.1.1"

dev loop

• Open Drilla.sln, run DualDrill.Server project to start a backend server

• optional In DualDrill.JS directory, run node .\esbuild.mjs --watch so ts code gets rebuilt automaticall on change

• Open browser, visit https://localhost:7117/desktop for basic rendering.

• visit https://localhost:7117/ilsl for basic C# IL to shader translation development

• optional add DUALDRILL_DATA_ROOT to environment variable for mesh/texture data

NOTE when runtime identifier is required to build/run, i.e. we need use x64 runtime identifier, Any CPU will not work

ILSL

ILSL is a C# embeedded language which could (planning) be compiled to multiple shader language runnning on GPU.

ILSL code is a subset of valid C# code, with custom attribute to extend its semantic for shaders.

ILSL's compiler currently support runtime compilation of dotnet's bytecode CIL(MSIL) to WGSL source text.

Features:

• WGSL backend
• control flow: if/loop
• function scope variable declaration
• priitive arithmetic/bitwise/logical/relational operation
• basic primitive type mapping
• vector type mapping
• some vector based intrinsic functions
• matrix type
• array type
• texture type/sampler type
• read/write buffers
• auto detect custom helper functions without additional attributes
• shader stage attributes
• group/binding attributes
• custom struct declaration
• shader relfection for uniform/vertex buffer layouts
• C# getter/setters
• CUDA backend
