GPU Particles (GF6800)
|
Hi there,
I wrote this DX App a while ago after I read Lutz Latta's article about "Building a Million Particle System"... I must admit, I didn't reach 1M particles *g* but 65k is sufficient for a small camp fire I think *g*
The whole update pro... |

Navigation Mesh & Cost Function

Hi there,
I have a problem, finding the "best" path on my navigation mesh (convex polygons of arbitrary size, auto-generated from level geometry).
Here is a picture to illustrate my issue:
The blue polygons (A-J) are my navigation po... |

Artifacts when using XYZRHW vertices
|
Hi,
I ran into a strange problem, while rendering icons and fonts/characters for a GUI. As usually I set up a vertex structure with XYZRHW coordinates, I apply an offset of { 0.5/textureWidth, 0.5/textureHeight } to the UV-coordinates. Then I rend... |

It was nice to find some actual code that isn't written in pseudo-language or described by mathematical equations that I can't understand :)

Problems "solved" ;)
I added an incomplete funnel search into the A* pathfinder for distance calculation and it looks beautiful so far. I took the code from Modified Funnel Algorithm, refactored it a bit to suit my data-structures and needs and it... |

Thanks for your reply. I "played" around with the multiple-nodes per edge solution, but my coworkers were not very pleased with it. There were still situations where the calculated path was a not "realistic enough" (as they say). *AllDesignersShouldB... |

First of all, thanks for the response. The glowing thingy is only called 'Smoker' because it uses a simple smoke update process :)

[SOLVED] Particle System using Hardware Instancing
|
Hmm, afaik there should not be much difference between 6000 or 6500 particles. Can go into details / post some code how you update and render your stuff ?
I did something similar months ago and it worked fine with 1 or 65k particles - but I didn't... |

what's the key to make a forest scene
|
Rendering Instanced geometry is the way to do this. Try to reduce the number of DP calls you have to make. In our current project we make heavy use of this. Nearly every object in the world is rendered with instancing using vs.1.1 / 2.0 shaders - it'... |

one shader to another

...can a vertex shader output (the vertex with light calculated) be the input of another vertex shader??? how do I do that?
You can't. And imho it's not really useful. Why do you want to do the lighting in object-spa... |

Deferred Shading, Can you do Bump mapping?
|
Sorry if I nail you down on this, but I believe that there is no tradeoff in quality. :)
If I sent the LightVector in textureSpace to the pixel shader it will be interpolated (therefore normalize it again). The so called ps.2.0 way will sent... |

In PS2.0 it is common to transform the normal from the tangent space normal map from tangent space into world space, then dot3 the world space light with the world space normal. The dot3 doesn't require... |

I see you use tex2Dproj(...)
I use tex2D... I looked it up in my book and on msdn and it just says its a 2D projective lookup, whats the difference between the two? thanks
