3: Vertex Shaders Version
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
Converts coordinates from Object Space (mesh origin) →right arrow World Space →right arrow View Space (camera) →right arrow Clip Space (screen). Vertex Shaders Version 3
This is where you apply custom effects like waves, grass bending, or character skinning. This allowed developers to control how often vertex
Version 3.0 introduced true if-else logic and loops, enabling shaders to skip unnecessary calculations and handle complex animation logic. Version 3
A vertex shader's primary job is to process each vertex of a 3D mesh before it is rasterized into pixels:
Passes transformed data (and any extra attributes like interpolated colors) to the fragment/pixel shader. Shader model 3 (HLSL reference) - Win32 apps
Reads raw vertex data (Position, Normals, UVs, Color) from memory.
