render state management
|
What I'm concerned about is trying to render the scene with as few state changes as possible. For example, in an RTS with 1000 units of 5 different types, if we render all units of each type in a row we can render all 1000 units with just 5 state ch... |

separating physics and rendering into different threads
|
I've been thinking about splitting up my physics and rendering subsystems into their own separate threads. The idea is that I'll be able to updat my physics objects for the next frame while the current frame is still rendering, instead of letting my... |

development environment

I'm a bit at a loss here as to how I should go about setting up a usable development environment for websites/web applications. Right now I'm doing all my PHP development simply by SSH'ing into my host server and then visiting the script I'm writing... |

Buying a TV
|
My 21 inch CRT from a trillion years ago is just no longer good enough to satisfy my gaming needs. It's heavy, takes up a ton of space relative to the screen size, and is standard definition. So I'm looking into getting an LCD panel TV.
I've got... |

Acrobat Professional: Buggy?
|
I'm not certain there has ever been a time in my life when Acrobat has functioned properly, but now it's just not functioning at all. I can't view PDF files in a web-browser anymore (Firefox hangs if I try). If I try to download the PDF view it out... |

Tracking memory leaks in C++
|
Memory leaks as we all know are an annoying problem. But again I'm sort of hung up trying to think of a way to avoid them. I know how smart/intrusive pointers work and how to use them, but this feels like an incomplete solution. If I forget to use... |

This doesn't look good
|
I think something is wrong with my computer: According to the Windows Task Manager the CPU is always about 30% or 40% in use because of the programs spoolsv.exe, csrss.exe and nvsvc32.exe. I'm not even hooked up to a printer, so I don't know what s... |

Cell phone help

This is probably a fairly obscure problem. I'd ask it on the T-Mobile website, but I don't know the account information since my parents own the account.
So I come to you guys with my question:
I have a Samsung SGN-X475 phone. Tonight I g... |

Gamedev.net's worth

I just realized today that everything I know about game development and programming I have learned either directly or indirectly from Gamedev.net, with the sole exception of the single computer science class I have taken here at the university (thoug... |

College + videogames - tv = ?

So, I'm in college, and my dorm room isn't exactly spacious (obviously, no one has a spacious dorm room) yet I'd like to be able to play videogames. Since I don't have a lot of room for a TV, I was wondering if it'd be possible to use my laptop... |

Lines of code in a lifetime

If x=lines of code and y=lines of productive code, the x-y probably equals about 3.
Heh, you've only written 3 unproductive lines of code in your whole life? |

The best openGL Games EVAAAR!?

How about FreeCiv and Tux Racer.
Also, here's a list of Linux games, most of which are likely opensource and written with OpenGL. |

Does high school really help?
|
Weighted grades are pointless and colleges don't care about how your school weights grades anyway. Colleges have their own means of assessing a students GPA and what that means. So don't worry about that.
As for your classes: if you aced your AP... |

(not)Attending University Lectures

When I was in my first semester of school the thought of missing a lecture was abhorrent to me. But, then I slept through one of my economics lectures and realized it made no difference at all to my education, so since then I've been skipping l... |

Batching! That's the word I was looking for. That should help me find some more resources about this type of thing.

XNA- 2D jumping
|
Two things: 1) you are only doing this jump logic when KeyJustPressed(Key.Space) is true, which should only be for one frame, since after that Key.Space won't have been just pressed anymore. And 2) you are incrementing position.Y by j... |

Calculating the Field Of View
|
Field of view is actually a measure of the vertical field of view. So the y axis would be tan(fov/2) and the x axis would be tan(fov/2) * aspect. |

Perspective Z/W Depth

Can you post your shader code as well as the projection matrix you're using? When done correctly the projection matrix will take a point and project it onto a plane in the z axis, and the w coordinate will have the original z value. Every proj... |

lighting related questions
|
In the shader where you calculate the diffuse lighting, instead of doing
Out.diffuse = dot(lightDir, In.normal) * In.diffuse;
do this:
float sharpness = 0.2;
float4 df = dot(lightDir, In.normal);
Out.diffuse = sign(df) * pow(df, sharpness) * I... |

Go to Project->Properties, then in the side panel click Configuration Properties, then C/C++, and then General. There should be an option to set the warning level. I usually choose the highest level (/W4) and set it to treat warnings as errors,... |
