Understanding BMP better

Wed, 12 Jun 2013 10:42:48 -0700

HI Everyone.
I'm not sure if I have picked the right forum or not, or even the right place to ask this question.
By the way ...
Today I opened a .bmp file for the first time and I saw somethings.
What I understood was that the first (almost) 50 characters consists some things I couldn't understand.
And the remaining consist 3 * pixels characters.
I believe that they determine how the RGB should be mixed.
BUT what made me create this thread was that when I tried to edit it with notepad, neither Paint nor WindowsPhotoViewer couldn't open/read/render it anymore.
I even tried replacing a character like : 'ÿ' with itself, but it couldn't render it anymore.
Is something wrong with notepad (I mean the way it saves the file) or something else.
THNX!
I tried reading BMP in wikipedia, but it didn't help, was hard.

Fri, 22 Feb 2013 05:49:31 -0700

Hello Everyone!!!!

I want to know that which is better Opengl or Directx for game developement and also which api is more powerful, efficient, fast & easy to use with C++.

somebody told me that with directx i ccan also render sound kinda stuff, is it true ?? and what with opengl . If chose opengl how i can render sound ?? which is more suitable for 3d graphics. iknow c++ well but dosent have exp with any api.

thanks in advance.

(sorry for grammar mistakes)

Fractal generation not fitting in expected range

Fri, 11 Jan 2013 21:27:21 -0700

Here's a problem description for generating a fractal:

If anyone has any insight into this problem and what I'm conceptually getting wrong it would be of great help. Thanks!

Fractal generation not fitting in expected range

Fri, 11 Jan 2013 21:03:49 -0700

The program will use the position of the mouse to set the value of a complex number of the form v = (a + bi). The program will then draw a large collection of points (or small circles) that are positioned at the locations given by sums of powers of this value v. In particular, you can calculate truncated sums of an infinite series of powers of v:

1.0 -- 0 ± v -- 0 ± v ± v^2 -- etc. ...

The first term of this series represents the position (0,0), which should appear as a point in the center of the screen. The next term of the series is 0 ± v0, which is the same as the two positions (1,0) and (-1,0). The next term gives four possible values, and you should draw a separate point for each of these values. The next term gives eight points, then 16, 32, 64, and so on. The program should calculate at least the first 10 terms of this series, and plot points for each of these, which corresponds to drawing at least 1023 points.

Calculate powers of v using the standard rules for multiplying complex numbers. For example v^2 = (a + bi) * (a + bi) = (a^2– b^2) + 2abi, where i = sqrt(-1).

The problem is with the sum of complex numbers. If v is larger than 1, which it can be since the range is -3 to 3. The usual behavior is for the numbers to blow up quickly, often reaching infinity. But the problem shows example fractals fitting within the range.

Direct X components "Not Available" on Windows 7 (Boot Camp).

Thu, 10 Jan 2013 04:21:35 -0700

First, here is the basic information about my 2009 MacBook Pro:
OS X 10.8.2 (12C60)
Processor: 2.26 GHz Intel Core 2 Duo
Memory: 4 GB 1067 MHz DDR3
Graphics: NVIDIA GeForce 9400M 256 MB
--
I have used boot camp to create a Windows Partition on my Mac and have installed Windows 7. The main reason I did so was for gaming purposes. When running Windows, when I attempt to run a game (Arma II), I get an error regarding my Display Adapter. Using Device Manager I made sure that the Display Adapter software had been updated, so I'm not sure that's the issue. The main problem is that Direct X Acceleration and Direct X 3D are "Not Available." I'm trying to find some way to enable the Direct X components and I'm not sure what to do. Is this a problem with the graphics card?

Also, I still have roughly 200 free GB on my Windows partition, in case anyone was wondering.

I'm really keen on running games on my Mac as opposed to purchasing a separate PC and if anyone could help me with this problem it would be much appreciated.

Thanks!
