SDSL Shaders for vvvv gamma / Stride

What Is SDSL

SDSL (Stride Shading Language) is Stride's shader language — a superset of HLSL with four key additions: shader classes with inheritance, multiple inheritance (mixins), the streams system for automatic inter-stage data flow, and override for clean method replacement. Shaders are defined in .sdsl files.

Streams System

Streams replace manual VS_INPUT/VS_OUTPUT structs. Declare once, access everywhere:

stream float4 MyData : TEXCOORD5;      // Declare a custom stream variable

// In vertex shader:
streams.MyData = float4(1, 0, 0, 1);   // Write

// In pixel shader:
float4 d = streams.MyData;             // Read (auto-interpolated)
