Orbitting Point Error?
|
In essence I am trying to orbit a point around another point at a fixed distance. For some reason however, when I calculate the distance(or display the line) the orbitted point is much 'further' away from the 'origin'(point it is orbitting around). I... |

Nevermind I trashed my code
|
So I'm making a quad-tree. So essentially I am flattening the Camera Frustum(to the X/Z axis), and testing to see if it holds a bunch of squares or intersects them. The faster the routine the better.
If it helps at all my square is a true square(... |

I'm losing my mind here. I'm working on a segment to AABB intersection script. This has cost me 12 hours of my life I can never have back. The Line segment verse Line segment, I've been using apparently only works under certain conditions a... |

[solved](XNA) 3-D HUD? Overall confusion.
|
So doing 2-D HUDS is exceptionally easy in XNA. I'm grateful for that!
However I'm confused how to do a 3-D HUD and am at a lack for resources referring to such. By 3-D HUD I'm referring to say, a rifle model(Ex: "CoolGunD00d.X") glued/stuck to th... |

Get angle of intersecting line-segments?

How do I get the angle of two intersecting line segments?
I'm trying to make a script so that when a segment intersects with another it reflects back(like bouncing a ball against a wall). This is a 2-D problem.
I already have the point of inter... |

[solved]Line Line Intersection
|
All I have to do is:
- Make sure they aren't parallel
- Calculate Point of Intersection
- Check to make sure point is on both lines?
Anything else I should be worried about?

[solved]Find Y on 3-D Line
|
Okay so I have a 3-D line. I have the two end points.
Which means I can calculate the slope.
I want to find out what the Y is on the line using the X and Z locations. How do I go about doing this?

Happy New Years!!
Hahaha, I have to say thank you so much my friend. That was the problem entirely.
edit: now it's time to refine that ugly and abstract code. |

Is it going to be significantly slow to test every single point? With a method such as:

float Orientation1 = Orientation(A, B, Point),

Thanks for that link. However, I've already seen it. My problem with it is it has to be done at compilation(Custom Content Processor). Does this idea only work at compilation time, or is it feasible to accomplish this just during run time?

if your camera hit's a wall it's supposed to just keep sliding but not go through the wall. I figured it out now though. Thanks a bunch! |
