The vertex shader is the one of the two original shaders introduced in Direct3D 8, and it is the only shader besides the pixel shader that must be provided before triangles can be rendered. It's kind of a big deal.
Video
The tutorial video is on YouTube here.
- What is a Vertex Shader (vs) and its position in the pipeline 0:20
- A vs takes in vertices of the geometries and applies transformations to them
- Our current pipeline function
ProcessVertices()does this in the most basic form: it applies rotation and translation to move vertices of the mesh from object space to world space - In this video, we will be making the vs configurable
- Code implementation walk-through 1:14

-
- - We apply a
std::transform()on the vertices vector - - We create a new datatype
VSOut, giving the vs the power to change the datatype of the output vertices - - Each vertex shader will define its output type
- - We apply a
