Hello,
In geometry shader, a quad is transformed in two triangles.
I can address a particular vertex in each triangle using “gl_in[i].gl_position”
I can address a particular instance using TDInstanceID()
But I dont know how to adress a particular primitive (here a triangle)
Somebody know how to do it?
Thank you in advance,
Jacques

Searching in Kronos website, I found the solution:
gl_PrimitiveIDIn
Sorry!
