Normal maps

Hello,

I’m trying to render the scene normals as post effect. Is possible to achieve something like this with post processing?

1024×578

Or any ideas how to achieve something like that? Thanks.

as material

gl_FragColor = vec4(vNormal.x, vNormal.y, vNormal.z, diffColor.a);

U can create custom pass, save normals to texture and use as postpocess

EDIT: with considering a normal map:

gl_FragColor = vec4(normal.x, normal.y, normal.z, diffColor.a);

By creating custom pass do you mean doing it in a technique? Can you make a longer example? thanks. I’m very very new to CG and I’m trying to learn it with Urho3D.
I saw normals are very important to achieve different effects and I simply got stuck

By creating custom pass do you mean doing it in a technique?

in a technique and in renderpath

Can you make a longer example? thanks. I’m very very new to CG and I’m trying to learn it with Urho3D.

renerpath Deffered.xml writes normals to texture
for custom passes u can see also github.com/1vanK/Urho3DOutlineSelectionExample
