[SOLVED] Regarding geometry buffer renderer and gBuffer outputs

How do i do that? which function is to be called?

I have done it in the PG, you need to set the renderList property of the geometry renderer:

geor.renderList = [box];

One last thing though. How do i fix the plane to not move on user input. I want to keep the plane as fullscreen quad but allow the camera transforms to only effect the cube?

The easiest way is probably to create a layer and set its texture to the gbuffer normal texture. That way, you don’t even need a plane:

If you really want to use a plane, see how it is done in this PG (functions makeShadowMapPlane to create the plane and showDepthMap to always have the plane facing the camera):

Change the value 256 line 168 to change the plane size

Another PG where a mesh stays at a fixed position/rotation wrt the camera:

Camera, maintain the meshes at the same position relative to screen during screen resize

You can try to work in NDC space and come back to world coordinates to position your meshes: https://playground.babylonjs.com/#F8PF6Z#2 NDC space is -1 < x < 1, -1 < y < 1, -1 < z < 1. So, (-1, -1, -1) coordinates correspond to the bottom-left pixel on the screen, in the near plane of the camera (z=-1). By calculating the right coordinates in this space for your boxes and projecting back to world space, the boxes will be located where you want. See the setPosition function in the PG. For th…
