Hi,
Awesome work. I really like it. This is a very good way to show your creativity.

Hey Desaxi, I´ve seen you uploaded a new version of your shader. What did you change?

Desaxismundi 07/04/2011 - 15:24

minor changes...as spotted by antokhio.

Adding this to a patch gives me an instant bluescreen, what are the minimal requirements for this?

antokhio 07/04/2012 - 23:39

seems fine here

He milo,
I've been trying to do the same, thanks for the hint towards this Sobel-Filter stuff ... I've been trying to do the calculation in VS.

Small fix though:
Neighbouring-Pixel-Calculation ignores amount-Pin for Displacement.
0 or negative values seemed pretty awkward.

So I changed

float tl = abs(tex2D (SampDisplace, In.TexCddispla +texelSize * float2(-1, -1)).x);

to

float tl = tex2D (SampDisplace, In.TexCddispla +texelSize * float2(-1, -1)).x*amount;

and so on ...

Hope I didn't break anything, but looks good.

Normals were computed for Displacement along Y-Axis, but all helppatches displaced along Z-Axis. Also I changed the float4 normals' w-component to 0 ...

I changed this line:
float4 N = float4(normalize(float3(dX, 1.0f/normalStrength, dY)), 1.0f);

to

float4 N = float4(normalize(float3(dX, dY, 1.0f/normalStrength)), 0);
