New Release D3D9Client Development

[SolarLiner]

That, maybe, is why I can't commit to sourceforge anymore: TortoiseSVN 1.8
Meh, if I knew it...

"XML parsing failed: (400 Bad Request)" will be fixed in Subversion 1.8.1:

D3D9 Crashes.

Every time I try to run Orbiter in D3D9 client it says "Critical error has occured. See orbiter.log for details." So I pull up orbiter.log with the notepad and it says:
D3D9Client:WARNING: [Hardware has only a limited non-power of 2 texture support]
D3D9Client:WARNING: [Insufficient Vertex Shader. Attempting software vertex processing...]
D3D9Client:WARNING: [Not a pure device]
D3D9Client:WARNING: [No Hardware T&L]
D3D9Client:WARNING: [No Hardware MipMap auto generation]
I have no clue what this means and how to fix the problem.

I have no clue what this means and how to fix the problem.

What is your graphics card?

 

[Noeyedeer]

What is your graphics card?

I'm not very good at computers so I think by graphics card you mean 3d device as shown in the video section of the launchpad.
If so: Mobile Intel(R) 945 Express Chipset Family
Not the best so I won't be too surprised if d3d9 won't work on my computer.

Mobile Intel(R) 945 Express Chipset Family

Yeah, that isn't compatible with D3D9Client.

 

[Noeyedeer]

Yeah, that isn't compatible with D3D9Client.

:facepalm: Oh well. Didn't need it that much anyway.

Jarmonik,


Yes, the black flickering occurs with the Rendering set to Disable.


Thanks,

I have a little problem with R11: When the spacecraft main engines are on, those faces that are lit by the engine flames, are flickering, (the faces getting inverted, or it's just becomes black, i don't know, i can't really see as it happens fast, and randomly). Why is that?

If I can quote this (because it's a bit old post), I say that this local light sources flickering happens to me, but not for the DG engines (why? I don't know), but for every other types of local lights (example for the PBLights of the Shuttle Fleet)

I have an ATI Radeon HD 5700, and it does happen when I remove every reflections from the ships.

Are you talking about DG-IV? It doesn't have engine lights.
I played with all settings, it's happening always.

 

[SolarLiner]

Nope, the default Delta Glider.

Here is a new build of the client for testing the lighting issue. I have no idea what's wrong with the local lights and I can't reproduce the problem and I can't find anything wrong from the code. So, if you could test the new build and see if it still produces the local lights problem.

If the problem is still present.
1) Then find D3D9Client.fx file from /Modules/D3D9Client/
2) Locate the following code section

void LocalVertexLight(out float4 diff, out float4 spec, out float4 dir, in float3 nrmW, in float3 posW)
{
    float3 diffuse = 0;
    float3 specular = 0;
    float3 direction = 0;

    int i;
    for (i=0;i<gLightCount;i++) 
    {
        float  dist  = distance(posW,gLights[i].position);
        float3 relpW = normalize(posW-gLights[i].position);

        float att    = saturate(1.0f / (gLights[i].attenuation[0] + gLights[i].attenuation[1]*dist + gLights[i].attenuation[2]*dist*dist));
        float spt    = saturate((dot(relpW, gLights[i].direction)-gLights[i].param[Phi]) * gLights[i].param[Theta]);
        
        float d      = saturate(dot(-relpW, nrmW));
        float s      = pow(saturate(dot(reflect(relpW, nrmW), normalize(-posW))), gMtrl.specular.a);

        if (gMtrl.specular.a<2.0 || d==0) s = 0.0f;
        if (gLights[i].type==1) spt = 1.0f;         // Point light -> set spotlight factor to 1

        float dif = (att*spt);

        diffuse   += gLights[i].diffuse.rgb * (dif * d);
        specular  += gLights[i].specular.rgb * (dif * s);
        direction += relpW * (dif * d);
    }  
   
    diff = float4(1.5 - exp(-1.0*diffuse.rgb)*1.5, 0);
    spec = float4(1.5 - exp(-1.0*specular.rgb)*1.5, 0);
    dir  = float4(normalize(direction), 0);
}

and replace it with this one

void LocalVertexLight(out float4 diff, out float4 spec, out float4 dir, in float3 nrmW, in float3 posW)
{
    float3 diffuse = 0;
    float3 specular = 0;
    float3 direction = 0;

    int i;
    for (i=0;i<gLightCount;i++) 
    {
        float  dist  = distance(posW,gLights[i].position);
        float3 relpW = normalize(posW-gLights[i].position);

        float att    = saturate(1.0f / (gLights[i].attenuation[0] + gLights[i].attenuation[1]*dist + gLights[i].attenuation[2]*dist*dist));
        float spt    = saturate((dot(relpW, gLights[i].direction)-gLights[i].param[Phi]) * gLights[i].param[Theta]);
        
        float d      = saturate(dot(-relpW, nrmW));
        float s      = pow(saturate(dot(reflect(relpW, nrmW), normalize(-posW))), gMtrl.specular.a);

        if (gMtrl.specular.a<2.0 || d==0) s = 0.0f;
        if (gLights[i].type==1) spt = 1.0f;         // Point light -> set spotlight factor to 1

        float dif = 1.0;

        diffuse   += float3(1,1,1) * (dif * d);
        specular  += float3(1,1,1) * (dif * s);
        direction += relpW * (dif * d);
    }  
   
    diff = float4(1.5 - exp(-1.0*diffuse.rgb)*1.5, 0);
    spec = float4(1.5 - exp(-1.0*specular.rgb)*1.5, 0);
    dir  = float4(normalize(direction), 0);
}

After making the change, local lights won't work properly. (color and distance attenuation is gone) But does it remove the "black" artifacts from the local lights ?

There is also a frame rate limiter added. The first parameter in D3D9Client.cfg. Zero will disable the limiter, also a low values will produce a lot of tearing so a minimum practical value is about 200. (This is unrelated to the lighting issue)

 

[jarmonik]

Any feedback ?

 

[Cras]

Any feedback ?

I have tried the new build, i cannot speak of the local light issue however, I never saw that myself.

Would it be possible to add like, a trigger for the frame limiter inside the sim? Like as part of the debugger window?

 

[astrosammy]

Oh, sorry jarmonik, I tried it after you posted R11c, just forgot to post my results.

The local lights work perfectly. I did not have to replace the code section you posted above.
Thanks for the fix!

:hesaid:
Works for me too. I can now return to my video capture ... STS-135 video capture

 

[Kendo]

Works fine here, without the code. :hello: :thumbup:

 

[sitha241]

Here to
Tnx

 

[jarmonik]

D3D9Client R12

Here is R12 release. If everything is alright then I'll upload it to CodePlex.

 

[jarmonik]

I'll try to include that in the next release. The status of the debug controls isn't saved anywhere. Therefore, you would need to enable it every time when the simulation is started. I'll try to find some better way to do that.
