This is the first time i am rendering to a 3Dtexture, from what i read I can only render to one 2D slice of the 3DTexture with a quad.
I want to render to all the texels so I have to clone those quads and each one renders to a different layer of the 3d texture, so i have this question.
When rendering to all the texels of that texture what is faster
- Using drawIndexedInstanced so every intance draws quad to each layer of the 3Dtexture
-Make the geometry shader clone the quads and each one render to different layer
the 3Dtexture is 100X100X100
