I'm so terribly sorry to re-re-re open this one, but I never fully succeeded at this one, SSAO.

SSAO Shader:

Texture2D t_depthmap : register(t0);
Texture2D t_normalmap : register(t1);
Texture2D t_random : register(t2);
SamplerState ss;

cbuffer SSAOBuffer : register(c0)
{
	float g_scale;
	float g_bias;
	float g_sample_rad;
	float g_intensity;
	float ssaoIterations;
	float3 pppspace;

	matrix view;
};

struct VS_Output
{  
	float4 Pos : SV_POSITION;              
	float2 Tex : TEXCOORD0;
};
 
VS_Output VShader(uint id : SV_VertexID)
{
	VS_Output Output;
	Output.Tex = float2((id << 1) & 2, id & 2);
	Output.Pos = float4(Output.Tex * float2(2,-2) + float2(-1,1), 0, 1);
	return Output;
}

// Helper for modifying the saturation of a color.
float4 AdjustSaturation(float4 color, float saturation)
{
	// The constants 0.3, 0.59, and 0.11 are chosen because the
	// human eye is more sensitive to green light, and less to blue.
	float grey = dot(color, float3(0.3, 0.59, 0.11));

	return lerp(grey, color, saturation);
}

// Ambient Occlusion Stuff --------------------------------------------------

float3 getPosition(in float2 uv)
{
	return t_depthmap.Sample(ss, uv).xyz;
}

float3 getNormal(in float2 uv)
{
	return normalize(t_normalmap.Sample(ss, uv).xyz * 2.0f - 1.0f);
}

float2 getRandom(in float2 uv)
{
	//return normalize(t_random.Sample(ss, uv ).xy * 2.0f - 1.0f); // ~100FPS
	return normalize(t_random.Sample(ss, float2(600, 800) * uv / float2(60, 60)).xy * 2.0f - 1.0f);
}

float doAmbientOcclusion(in float2 tcoord,in float2 uv, in float3 p, in float3 cnorm)
{
	float3 diff = getPosition(tcoord + uv) - p;
	const float3 v = normalize(diff);
	const float d = length(diff)*g_scale;
	return max(0.0,dot(cnorm,v)-g_bias)*(1.0/(1.0+d))*g_intensity;
}

// End

float4 PShader(VS_Output input) : SV_TARGET
{
	// ADD SSAO ---------------------------------------------------------------
	const float2 vec[4] = {float2(1,0),float2(-1,0),
				float2(0,1),float2(0,-1)};

	float3 p = getPosition(input.Tex);
	float3 n = getNormal(input.Tex);
	float2 rand = getRandom(input.Tex);

	float ao = 0.0f;
	float rad = g_sample_rad/p.z; // g_s_r

	//**SSAO Calculation**//
	int iterations = 4;
	for (int j = 0; j < iterations; ++j)
	{
	  float2 coord1 = reflect(vec[j], rand)*rad;
	  float2 coord2 = float2(coord1.x*0.707 - coord1.y*0.707,
				  coord1.x*0.707 + coord1.y*0.707);
	  
	  ao += doAmbientOcclusion(input.Tex, coord1*0.25, p, n);
	  ao += doAmbientOcclusion(input.Tex, coord2*0.5, p, n);
	  ao += doAmbientOcclusion(input.Tex, coord1*0.75, p, n);
	  ao += doAmbientOcclusion(input.Tex, coord2, p, n);
	}
	ao /= (float)iterations*4.0;

	ao = saturate(ao);

	return float4(ao, ao, ao, 1.0f);
}

How I write my depth map to the ssao:

VS
output.depth = output.position.z / output.position.w;
PS
float depth = input.depth;
output.Depth = float4(depth, depth, depth, 1);

How i write my normal map to the ssao:

VS -- I think this is wrong
output.NormalW = mul(mul(worldMatrix, viewMatrix), float4(normal.xyz,0) );
PS
output.Normals = float4(input.NormalW, 1);

Render Result:

Ehh.

Again, I'm so sorry for re-posting this, it's just, i really want this feature completed (well, working at least).

Thank You, like always...

So how would the depth shader be written correctly to the SSAO shader?

Thank you for your interest by the way, appreciate it!

Ok, it is a bit better now in the sense that it doesn't just become randomly black: (SSAO Map)

But this isn't right yet, well I don't think it is, I mean look at the left of the cube, where the left side is rendered, it's black, why?

Ohh, and belfegor, about the matrices, you were right!

How I write my depth map to the ssao:

VS:

output.position = mul(position, worldMatrix);
output.position = mul(output.position, viewMatrix);
output.position = mul(output.position, projectionMatrix);

output.NormalW = mul(float4(-normal.xyz,0), mul(worldMatrix, viewMatrix));

// Store the position value in a second input value for depth value calculations.
output.depthPosition = output.position;

PS:

// Depth
float depth = 1.0f - (input.depthPosition.z / input.depthPosition.w);
output.Depth = float4(depth, depth, depth, 1.0f);

// Normals
output.Normals = float4(input.NormalW, 1); 

Now, is this the correct way to map the depth and the normal maps?

Sorry about the normals, just testing, and forgot it there...

The result, is this correct?

Now looks like this, look at the variables in the upper left corner:
