How to determine the distance between two computers by their IP adress
|
Hi all,
I'm a newbie in network. I'd like to know if it's far or near between two computers, by their IP adress or by their ping value( the latency between them)?
Can anyone tell me these in detail?
Thanks in advance! |

Hi all,
I want to use NV_vertex_program3 in GLSL. The spec says that one should add
OPTION NV_vertex_program3;
at the begin of the vertex program. But when I added it to my GLSL vertex shader code, the program generated errors as foll... |

Realtime Subsurface Scattering Skin Rendering

Hi,
This is my Realtime SSS skin Demo. It is using Translucent Shadow Maps(TSM) to calculate the Subsurface Scattering for every vertex, via the Vertex Texture Fetch(VTF) technology of Shader Model 3.0. VTF allows sampling textures at the vertex pro... |

How to use noise() in HLSL

hi all,
I use it this way:
fragout Out;
float4 color=tex2D(TextureSampler, TexCoord);
float cc=noise(color);
Out.color=float4(cc,0.0,0.0,1.0);
Then it prompts this error:"error X4532: cannot map expression to pixel shader instruction set."... |

A Question about Texture Coordinate Generation

Hi all,
When I using Cg to sample a texture whose texture coordinate is generated using glTexGeni() automatically, I come across an odd question. Let's look at follows:

Is there f4tex2D() funtion in HLSL?
|
Hi all,
There are some functions such as f4tex2D() and f4texRECT() funciton in Cg, then are there such functions in HLSL?
It seems that i cannot find them in HLSL.
If not, how do i simulate these functions in HLSL?
Thanks in advance! |

Thank you very much, hplus0603,UltimaX,Ezbez,Antheus.
Ask another question, how to select the nearest node in the P2P network? Which is the criterion? the latency?
Thanks. |

How to Use NV_vertex_program3 in GLSL

Quote:Original post by V-man
Gf 7300 is a SM 3 GPU and the VS instruction limit is 512.
Gf 8 is 64K
There is no !!ARBvp2.0 so NV uses ARBvp1.0 and inserts their custom instructions that's why there is a OPTION NV_vertex_program3; in there.
Oh... |

Thanks. I'll see the movie at my leisure. |

Yeah, it's a bit dark, because I modulate the base texture and the SSS result. Maybe I'd magnify the modulation, moreover add specular light.
