opengl - How to create textures within GPU -

-

Can anyone tell me how to use hardware memory to make texture in OpenLL? I am currently running my game window mode, do I need to switch to fullscreen to use the hardware?

If I can make texture in hardware, then what kind of texture (except hardware memory) have no limit? And then how can I cache my texture in hardware? Thank you.

It should be covered by almost all texture tutorials of OpenGL. For example, and.

For every makeup you first need the texture name. The name of a texture is like a unique index for a single texture. Every name indicates a textured object whose own parameters, data, etc. are used to get new names. I do not know there is a limit other than the UIT category (2 ^ 32). If there is, you will probably get 0 for all the new textured names (and a mistake error).

The next step is your texture (see) after all the operations that use or affect textures will use the texture specified by the texture name which you used as the parameter of glBindTexture. You can now set the parameters for texture () and upload texture data (for 2D texture), after calling GlTexImage you can also freeze system memory with your textual data.

For static texture, all this has to be done once only if you want to use texture, then you need to re-pair it and enable texting (glEnable (GL_TEXTURE_2D)).

Size (width / height) for single texture is limited GL_MAX_TEXTURE_SIZE This is usually 4096, 8192 or 16384. It is also limited by the available graphics memory because it should fit in with some other resources like framebuffer or top buffer. All textures can have large available memory simultaneously, but then they will be swapped.

In most cases, the graphics driver should decide which structures are stored in the system memory and in graphics memory you can however give some texture either with a high priority with the glTexParameter .

Edit: I will not be worried too much, where the textures have been stored because the driver normally does a lot of things with that good job usually used Graphics is more likely to be stored in memory. If you set a preference that is just a "signal" for the driver, then how important it is to stay on the graphics card for texture, it is also possible that the priority is completely ignored. You can also see where the texture is currently.

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...
