[QUOTE=Richy19;35872991]If in OpenGL(2.1) I have a scene like the left, therefore the user views the right.
Does the cube actually get rendered?[/QUOTE]

The vertex transformations and whatnot will always occur. The GPU will try to create fragments for every polygon, but the actual shading may or may not occur depending on the results of depth testing. This is why a lot of games do early-z passes or render front-to-back; it saves on shading overhead in forward renderers.

Effectively, you may save on some fragment shading, but you still have to actually process the primitives. This is why we have visibility testing and occlusion queries in games.

Hello again folks, I require assistance once again in Visual basic 2010. I wouldn't ask this if I hadn't committed hours trying to solve it myself. But I need to get this nifty little simulation give somewhat logical numbers instead of astronomical coordinates and infinite decimals.

Here's what I have trouble with in my nuclear strike simulator.
There's a certain percentage of people from the total population of the city in certain range, and certain percent of those people in those ranges die.

Public Class Form1
    Dim Oulu As Integer = 150000 ' Population of this city
    Dim Oulun_pinta_ala As Double = (1000 * 1410.17) ^ 2  'Area of whole city turned from square kilometers(1410.17) to meters
    Dim Oulun_asukastiheys As Integer = Oulu / Oulun_pinta_ala 'population density
    Dim Asukkaita_1140m_säteellä As Double = (1140 * 1140) * 3.14 / Oulun_pinta_ala * Oulu 'population in this range in meters
    Dim Asukkaita_3050m_säteellä As Double = (3050 * 3050) * 3.14 / Oulun_pinta_ala * Oulu 'population in this range in meters
    Dim Asukkaita_6200m_säteellä As Double = (6200 * 6200) * 3.14 / Oulun_pinta_ala * Oulu 'population in this range in meters

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        If lblAsukasmaara.Text = "0" Then
            MsgBox("Valitse Kaupunki")
        End If

        If lblAsukasmaara.Text = Oulu Then

            kuollut1 = (100 - 88) / 100.0 * Asukkaita_1140m_säteellä 'death toll in these ranges
            kuollut2 = (100 - 33) / 100.0 * Asukkaita_3050m_säteellä
            kuollut3 = (100 - 11) / 100.0 * Asukkaita_6200m_säteellä
            yht = kuollut1 + kuollut2 + kuollut3
            tulo1 = kuollut1
            tulo2 = kuollut2
            tulo3 = kuollut3

But I get results like this (note that "kuollut", "kuolleita" etc means "dead")

Kuolleita 1140 metrin säteellä: 0,0369376203597919
Kuolleita 3050 metrin säteellä: 1,47622462665414
Kuolleita 6200 metrin säteellä: 8,10310283100606
Kuolleita yhteensä: 9,61626507801999

please forgive my stupidity :c

Hey everyone. I am in c++ programming in college and I could use a little help with a final project.
This is my project;

Your programming assignment is to develop a program to find out the winner of the gymnastics competition.  The winner is the gymnast with the highest score.  Each gymnast will receive a score from seven (7) judges.  The highest and lowest score will be thrown out. The remaining five scores will be averaged to determine the gymnast final score. The output will list each gymnast with their final score followed by the overall winner.

 

Your input will come from a file with the name - OLYMPICS.TXT and have the data listed as follows

OLGA KORBUT 8.8 7.8 3.4 8.9 10.0 6.5 9.9

MARY LOU RETTON 5.6 5.5 6.5 7.5 4.8 2.1 4.5

NADIA COMANECI 9.9 8.9 9.4 9.3 9.6 8.8 9.2

The number of Gymnasts in the file will vary.

 

The results will be written to a file called - FINAL.TXT and have the format of

Gymnast                                    Score

OLGA KORBUT                            8.38

MARY LOU RETTON                    5.38

NADIA COMANECI                       9.28

 

The winner is NADIA COMANECI

I am having trouble with this concept. All we have learned this year is basic stuff. This one has to do with loops and files. I am not sure how to go about this. I have tried doing some code for the past few days and cant figure this out correctly. Any tips or help will be greatly appreciated.
What I know I should do is create a loop that inputs all the values and creates a high low type deal. I am not sure how to go about that correctly.

Use sscanf to parse the data for each line, then loop through the numbers to find the highest and lowest score to discard them. Then get the remaining five scores and average them. It'd look something like this:

std::ifstream File;
File.open("path/to/file.txt");
while (File.good())
{
char FirstName[32];
char LastName[32];
float Scores[7];
char Buffer[256];
File.getline(Buffer,256);
sscanf(Buffer,"%s %s %f %f %f %f %f %f %f",FirstName,LastName,&Scores[0],&Scores[1],&Scores[2],&Scores[3],&Scores[4],&Scores[5],&Scores[6]);
float Min =10;
float Max = 0;
for (unsigned int i=0;i<7;i++)
{
if (Scores[i]>Max)
{
Max = Scores[i];
}
if (Scores[i]<Min)
{
Min = Scores[i];
}
}
float Average = 0;
for (unsigned int i=0;i<7;i++)
{
if (Scores[i] != Min && Scores[i] != Max)
{
Average += Scores[i];
}
}
Average/=5;
std::cout << FirstName << " " << LastName << " average score is " << Average << "\n";
}

Sorry for the lack of formatting, chrome won't let me tab.

Would you be able to do it with like simple looping and basic file i/o? We have not done arrays. I am completely lost. I am very new to this stuff and we only covered basic input, basic control structures, and functions.. lol Basically where I am thrown off in the file is how to get the names first then loop through the 7 numbers, knock off high and low, then move on to the next one infinitely. I'm not sure how to go about that. I understand your code but we are not to that level yet and I need to write it in more simpler terms.. The professor would not like me using arrays when he has not even hit them.

I made myself a basic High Low code but I dont know where to go from here.

 #include <fstream>
using namespace std;

int main()
{
	ifstream scores;
	ofstream winners;
	int number, high, low;

	scores.open("scores.txt");
	winners.open("winners.txt");

	scores >> number;
	low = number;
	high = number;

	while (number >= 0)
	{
		if (number > high)
           high = number;

		if (number < low)
			low = number;

		scores >> number;

	}

	winners << "the highest number in the list is " << high
		    << endl << endl;

	winners << "the lowest number in the list is " << low
		    << endl << endl;

	scores.close();
	winners.close();

	return(0);
} 

I just made the input file a string of numbers.

It seems really pointless to avoid useful tools and abilities of the language. Your teacher shouldn't punish you for going above and beyond

[Protocol7]

Stringstream can help you when you have 3 names. Or one. So instead of parsing a first and last name you can just cin into a string.

Also, write a function to split up a string with space delimiters, and return a string vector full of it. Then use a stringstream to test if the vector index is a string or a double ( istringstream >> int won't do anything if the stringstream can't be converted to int) and then do stuff accordingly.

I keep getting this:

[quote]|36|undefined reference to `SOGLF::Keyboard::IsKeyDown(SOGLF::Keyboard::Keys)'|[/quote]

I have it declared as:
[cpp]
namespace SOGLF
{
class Keyboard
{
enum Keys{...};
static inline bool IsKeyDown(SOGLF::Keyboard::Keys key);
};
}
[/cpp]
and defined in a cpp file as:

bool result = false;

switch (key)

}
return result;

So I needed a position to screen method which is pretty much gluProject, so I wrote that:

[cpp]bool Renderer::Project(const Vector3f& position, const Vector2i& windowSize, Vector2f& result) const
{
Vector4f in(position.x, position.y, position.z, 1.0f);
in = m_projection * (m_modelView * in);

if (in.w == 0.0f)
{
return false;
}

in.x /= in.w;
in.y /= in.w;
in.z /= in.w;

in.x = in.x * 0.5f + 0.5f;
in.y = in.y * 0.5f + 0.5f;
in.z = in.z * 0.5f + 0.5f;

result.x = in.x * windowSize.x;
result.y = windowSize.y - (in.y * windowSize.y);

return true;
} [/cpp]

The only problem is that the screen position is still on the screen when the position I'm projecting is behind the near clipping plane. So in that situation, I either need a way to make it return a position thats outside the screen (so I can clamp sprites to the edge to see what direction something is in) or find out if the point is behind the near clipping plane.

[editline]13th May 2012[/editline]

It seems I can just return out if the w component is less than 0.001, seems to work and that's what the source engine does, so whatever, it's good enough for me.

You should define inline functions within the header file. Also, make sure you actually want/need an inline function.

[url]http://www.parashift.com/c++-faq-lite/inline-functions.html#faq-9.7[/url]
[quote]It's usually imperative that the function's definition (the part between the {...}) be placed in a header file. If you put the inline function's definition into a .cpp file, and if it is called from some other .cpp file, you'll get an "unresolved external" error from the linker.[/quote]

I'm trying make the player collide with the wall. The wall is a 31x31 cube but I can only make the player collide on the left face of the cube. I can't figure out how to add more sides without them overriding each other.[/QUOTE]

You could save the movement direction of the player and move it back with the reversed speed.

Else you do something like this inside the block collision test:

if((playerX+26 >= wallX)and(playerX <= wallX+26)and(playerY+26 >= wallY)and(playerY <= wallY+26))then
    if(playerX+13 <= wallX+13) then
        //Move player to left
    else then
        //Move player to right
    end
end

I could be wrong with those values, I basically are trying to determinate if the player is to the right/left of the block.

[Silverboarder]

I want to make a board game using Java. (to learn it better)
I am a beginner and i was wondering what imports to use and if anyone could point me in the right direction with where to start.
Also tutorials that i should definitely read for this.

I have an image with the board itself.
Things what i want to be able to do:
- i want to be able to specify the amount of players and then have that amount of pawns.
- a dice
- drag and drop the pawns

[marco_q73]

@Silverboarder

The real Drag & Drop interface works easy with components, but as you just
wish to DND with some own images within the scope of your own program
(and just within one JComponent) you can skip DND interface this and just
use the mouse listener for this.

For the easy way (just mouse listener) you just need minimal knowledge of swing.
You only want an initial frame asking how many players (possible board+pawn images)
and reuse this frame to add the a panel as canvas for the drawing.

More interesting is the Graphis2D interface, you will use it for drawing your images.
But in most simple case you will only use the drawImage.
Just make a subclass of JPanel and overwrite the paint. From here you can use the
Graphics2D interface. Add the mouse listener (to either frame or panel) and you're
almost done ;)

It becomes more complicated if you actually want to add game-logic etc.

The metric to get "circles" that look like diamonds is [img]http://latex.codecogs.com/gif.latex?\sum%20_{k=1}%20^n%20|a_k%20-%20b_k|[/img], and it defines taxicab geometry. Yours is just a squished diamond, so one axis gets scaled before summation.

Don't worry if that doesn't make any sense[/QUOTE]

Heh well its alright I got it now... Took me way too long to make this algorithm...

            float min;
            float high;

            if (sp.X > start.X && sp.Y > start.Y && (sp.X < start.X + 64 && sp.Y < start.Y + 32))
            {
                if (nc.X < 32)
                {
                    min = 16 - (nc.X / 2);
                    high = (nc.X / 2) + 16;

                    if (nc.Y > min  && nc.Y < high)
                        return true;
                }
                else if (nc.X >= 32)
                {
                    min = (nc.X / 2) - 16;
                    high = 32 - min;

                    if (nc.Y > min && nc.Y < high)
                        return true;
                }

Math is my weakness... and it really shows in my programming :/

[QUOTE=Richy19;35951387]Can anyone see anything in my shader class that would cause a segfault?

[/QUOTE]

use a debugger

set a breakpoint

and find out yourself

seriously that should be in the OP - "set a breakpoint and step through your code"

then put a breakpoint on the constructor and step through it until you find the offending line

In C#, is it possible to copy entire folders, to another folder, filled with different files that can be images, text, more folders, and files that have unknown file extensions.
