i wrote a little testing patch demonstrating my problem.
i want to make the geometry shader “instanceGrid” emitt one triangle for each vertices of a grid.
So if i have a grid resolution of 4 * 4 - then i want to have 16 triangles after my geometry shader.
From my understanding i have to use pointlist in topology in order to make the input of the geometry shader a single element array. But then is see points instead of - triangles at each point— results just dont make sense to me…
Would be really cool if someone could jump in - look at the patch and give me a little push in the right direction
Thank you guys.
