Triangulation to a shrink wrap?
|
Please see the pic below that is clearly a level from my in-development game.
Apologies this is a bit long, but I want to make sure you understand the problem space.
That mesh is generated purely in code from a hexagonal 2D tile editor. To make... |

Good Explosions?
|
I've spent a day finalising my particle effect editor and am pretty please with it. It can do a lot of things with more fine touches planned.
In fact, it can do everything apart from look good!
Talking mainly about flaming explosions and debris... |

Book Recommendation ?
|
Is there a good book for AI implementation that isn't centered around FPS or RTS games?
I'm looking for something that covers the more basic "old-fashioned" problems like how to actually write a chess/checkers AI or GO or basically any board game.... |

Turn-based RTS AI
|
Hi chaps. Can I beg a little help here? I'm not a newb to general AI programming stuff, but I just can't my head around where to start with putting a decent AI together for my current project.
It's a turn-based strategy game using a hex board and... |

Tracing a contour from hex data?
|
Running into a bit of a problem here, hoping someone can give me a lead.
I'm making a 3D level editor and I need to produce some smooth closed contour lines passing through the centres of the tiles that are on edges of distinct land masses.

Shadowmap Peter Pan Calculation?

I've abandoned my gradient shadows (largely from the ShaderX5 book) on account of ime it doesn't really solve anything - I get no acne but I have other issues that, at least in the sphere of stuff I do, are just as bad and therefore those many g... |

Catmull Rom Tension?
|
Any ideas how I can implement some sort of "Tension" parameter in my evaluator?
I'm getting positions via subdivision. My "GetPoint" routine first works out what segment I'm interested in and how long it is and gets a factor of 0-1 along that part... |

3D position from depth FOV problem
|
I pulled this out of a necroed thread on the topic:
// pnt is still in eye-space
float2 ss = ( newPoint.xy / newPoint.z ) * float2( 0.75, 1.0 );
float2 tx = ss * 0.5 + 0.5;
float depth = tex2D( depthMap, tx );
I'm doing exactly... |

Setting Wrap and Filter modes ?

Got another n00b question here please. When loading my textures, I set these 4 properties as I do the bind:
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
glTexParam... |

Rendering Fancy Vertex Formats?
|
Hi guys.
I've just started porting my DX engine to OGL (v2.0) and I have a core question I can't seem to work out.
I'm using shaders to do everything, (including simple stuff like drawing rectangles for reasons that aren't gonna change)
So I... |

Is "Real-Time Rendering, A.-Moller et. al." a good reference?
|
It's 50 quid on amazon here, which I guess does sound about right. Sorry to derail, I sometimes forget how far apart our currency numbers are. I don't remember paying 50 squids for it though.
Something vaguely useful: I agree it's a good book... |

Fixed angle lookup

Sounds like you're optimising in the wrong place to me. What *exactly* are you doing?
Surely nobody's gonna noticed if you only look at the closest 100? |

Quick and painless FSM techniques in c++?
|
@swift, I think I covered that. I wouldn't use an FSM solely for this task either, but I'd typically move on from there to control the main gameflow logic with it also.
There's also no reversal from me, I'm always advocating keeping it simple... |

No, he is correct. If you're coming from DirectX it's the opposite way, due to hlsl being ba... |

Slow Performance in Direct3D9 [solved]

It might well be your locking method letting you down. DX is very picky about that stuff, but it flies when you get it right.
About how many batches are you drawing per frame? |

It's just a general nebulous term that only takes on more specificity when you are talking about a definite article. "The renderer in this..." One guy could be refering to the specific bit of code that calls drawprimitive, whilst anothe... |
