3D File Formats for Games -

-

I'm starting up and trying to get good quality, up to date information on various 3D file formats The game is used in the development.

Clearly many games have been developed with many more custom 3D file formats, but I'm more interested in choosing a better solution using the more commonly supported format.

What are the most popular formats and what separates them?

Note Ideally, they should support animation, but I would also be interested in other formats which can be used to create maps or static objects.

In XNA, try to do something on your own (especially load data format)) Living with the flaws directly supported by the shelf is much more than living, at least it is how the document looks, and what I heard from a person bending the content pipeline (Runtime geometry generation) is needed And whom I know what he's doing, I think that x and FBX is going to be very much. Both of them support skeletal animation, and I think pay attention to the top too. I'm not sure exactly what Blender is capable of exporting those features, but if you want I can see it.

Blender 2.5 is finally supporting Good Collada (the current is not one and broken in many ways), and Autodsk Collada & Lt; -> FBX provides a good tool for conversion.

If you look at the hobby development community, you will see that id software data formats are very popular on one hand MD2 and MD3 vertex morphing character animation format, MD5 skeleton animation format, whose needs are clearly visible. Above, and on the other hand the BSP file format, which describes the game level.

One thing to speak for the BSP is that there is a good editor available (GTKRD and derivatives). This is an efficient format that can erase hidden geometry. However, the runtime cost of custom geometry creation is important in XNA, and the limitations of these formats are quite common on 64k upper and 64k polygons in the entire game level, which you can now dump onto the graphics card, display drop notable Will happen. So you do not get any benefit from supporting it.

I suspect that there are powerful, modern, available formats and tools for the colon-optimized level design, whose performance gains will translate into XNA.

If you are not already, you can see some links:

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
