Three.js SSAO on a smooth mesh produces flat-shaded results

I am using Three.js r97 and in my scene I have a mesh using BufferGeometry with valid normals. When I am setting material.flatShading = false I see a smooth mesh, but when I apply SSAO postprocessing to this mesh…

Incorrect depthTexture with SSAO

I’ve been puzzled lately as I’ve been attempting to get a THREE.DepthTexture to work with the Ambient Occlusion shader. I’ve had it working before with RGBA unpacking, but after reading about Matt Deslauriers’s project, Audiograph, I decided to…

OpenGL Computing Normals and TBN Matrix from Depth Buffer (SSAO implementation)

I'm implementing SSAO in OpenGL, following this tutorial: Jhon Chapman SSAO Basically the technique described uses an Hemispheric kernel which is oriented along the fragment's normal. The view space z position of the sample is then compared to its…

Calculating view space normal instead of world space

I hope you can help with this. I am currently using a deferred renderer and am trying to implement SSAO but that needs view space normals and I currently have world space normals, I am trying to work out how to convert them but keep getting…

ThreeJS SSAO with SSAA

i'd like to integrate the SSAO-Shader (Screen Space Ambient Occlusion) into my antialiasing render stack (Super Sampling Anti-Aliasing). The AA is necessary for high-quality rendering, the default antialiasing delivered by my gpu isn't always…

Three.js post process: FXAA does not work with SSAO enabled

In this simple test scene, I need SSAO and FXAA effects composed together, but I can't get it work. When SSAO is enabled, if I also enable FXAA the render gets black. In the fiddle, if you uncomment composer.addPass(FXAA_effect); you'll see the…

SSAO incorrect at z = 0 and at distance

So I tried to implement SSAO, but it is not working as intended. It seems to split at Position z=0 (worldspace), there is a white Line at position z=0. Also the Occlusion there doesn't look right. Plus at greater distance, so when moving the…

DirectX 9 HLSL SSAO?

I need a DX9 HLSL SSAO shader, but I have only limited knowledge of shaders. I'm trying to learn so that I can write one, but it's a steep curve. I don't understand most of the theory of SSAO, so any in-depth explanations would be great. While I…
