Is there a way to calculate interior angles of a triangle with side lengths?
|
As the title explains, is there a way to calculate all of the interior angles of a triangle given only, but all, lengths of the sides for a non right and triangle?
Thanks |

Triangle texture coordaintes calculation and other questions

Hey there,
I've recently been working on a ray tracer, and I'm wondering about how texture coordinates would work in a few situations. First of all, how do you calculate the texture coordinates of a triangle, a ray, and the point of intersectio... |

Ray Tracing idea
|
Hey there people, I have an idea that I would like some critique on. This idea is based on Ray Tracing and real time image processing like HLSL, GLSL and Cg. So first thing first, ray tracing is typically quite slow, and hence not real time... |

Hi, I'm in need of a quick square root function. I've looked into using the math.h one, but people seem to bash it for being expensive quite often, so I'm wondering if anyone has links to information on a faster square root function, or can... |

It seems there are a huge number of games just like this (as mentioned above). If you are really worried about it and in serious doubt, your best bet is to contact a lawyer. Although it can be expensive, it could be considerably less expensive than a... |

Hardly a reason to swear repeatedly at me given that first off it didn't take me the trigonometric rules all of which seem to offer no help in non right angle triangles, so cool it down. |

Do you guys use patterns?

I'm not sure if anyone is mentioned this yet because I don't have the time to read all the replies, but there's a reason they are called patterns... It's not like someone sat down one day and said "Ok, I'm going to write a proxy pattern", they c... |

I think the main thing that you should focus on at the moment is classes. They will help you separate things out much better, and encapsulate everything for a particular object. For example, all of the following could be grouped together under &... |

Hi, you may want to place your code between the source tags (http://www.gamedev.net/community/forums/faq.asp#tags). |
