Normal Visualizer help

HI,I want to code a normal visualizer using the Geometry shader however I’m not sure if I need a seperate Geometry shader for this or incorporate it into my current one. I don’t think the latter is possible is it? especially if you have already defined the layout i.e. layout(triangle_strip, max_vertices = 3) out.

Does anyone know the best route to take, especially when you are deforming vertices inside the shader. How could you visualize normals with the geom shader?

All the best

From here, it is said that a geometry shader

is designed to accept a specific Primitive type as input and to output a specific primitive type
