Version 3.0 introduced true if-else logic and loops, enabling shaders to skip unnecessary calculations and handle complex animation logic.
Passes transformed data (and any extra attributes like interpolated colors) to the fragment/pixel shader. Shader model 3 (HLSL reference) - Win32 apps Vertex Shaders Version 3
This allowed developers to control how often vertex data was fetched, making instancing (rendering many identical objects with one call) much more efficient. The Standard Vertex Shader Pipeline Version 3
Vertex Shader Model 3.0 (vs_3_0), introduced with DirectX 9.0c, was a major milestone in graphics programming. It transitioned vertex shaders from basic coordinate transformers into high-performance, programmable processors capable of complex logic and texture sampling.

Converts coordinates from Object Space (mesh origin) →right arrow World Space →right arrow View Space (camera) →right arrow Clip Space (screen).
