c - SetPixel equivalent on mac? -


I am currently writing a software renderer and found it after working on windows, about starting it Mack started thinking about

My question is: What is the equivalent of Win32 GDI SetPixel function? Plot a pixel on what I should be able to do (x, y).

I'm new to Mac development and the closest thing I got as an answer was to use the OpenLeal texture to attract one.

Is it possible to plot single pixels in OSX is?

short answer

Simply use LibSDL (preferably version 2.0).

Long answer

You have to take your pixel data from system memory to graphics memory. One way to do this is with OpenGL, you can think of OpenGL as a fancy API That lets you push data to system memory from system memory. It's okay to use OpenGL.

But if I want to use OpenGL then the issue of rendering such software is defeated ...

Graphics card Whether you like it or not you can not get any special portability benefits to avoid OpenGL, whether it is composing your pixels on the screen. Back in the 90's you could get a pointer to the framebuffer and push the pixels there, but that day has gone.

LibsdL is good because it gives you an API that lets you drag pixels into buffer, and then takes care of buffer on LibSDL screen.

SetPixel () is very slow, so you should use LibSDL on Windows.

अन्य ऑब्जेक्ट को एक ऑब्जेक्ट प्रकार के रूप में घोषित किया गया है, इसलिए इसमें नहीं है जो भी वर्ग आपने बनाया है, उसके गुणों में से कोई भी। यह उस वस्तु के समान होना चाहिए, जिस वस्तु को आप इसके साथ तुलना करने की कोशिश कर रहे हैं।

I am trying to set the size of nodes in this way: Size = circle, width = .5, label = "controller", style = fill, fillcolor = "# 8EC13A"]; But all three nodes are in different sizes, how can I set a fixed size? From the DOT guide on page 4 it says the following: When drawn, the actual size of a node is the most requested size and the required area for its text label, unless the is fixed = true , then the width and height values ​​are applied. . In this way you need to add fixedsize = true to your code

I am quite new to Unity, but I have created an app that sends a simple TCP message to the click of a button A very simple TCP server console application. This code works perfectly when I run it on my PC, but when I make it for Android and test through my phone the message does not reach the server. Am I doing it wrong? Is ordinary TCP interaction done differently with Android? Here is my Integration Code: Public Texture BTN Detection; Public GUIStyle style; TcpClient mySocket = New TcpClient (); Public Network Stream The Stream; Public string host = "my_ip_address"; Public Int32 port = 8888; Public sent Bull = false; Streamer; TheWriter; Streamer The Reader; Strange (ONGI) (if (GUI button (new rickety (screen.

I am very new to C # so that please stand with me ...

Additional methods for using the above Data Members ...} I would like to introduce both data members: IsSomething to True and SomeList to new list & lt; String & gt; () . Generally I will do it in the constructor, however, because it is a partial square, I do not want to touch the constructor (am I?). What is the best way to achieve this? Thanks PS I am working in ASP.NET MVC, adding functionality to some models, so partial orbit. updated for C # 6 The ability to assign a default value to C # 6 auto-properties added value can be any expression (it does not have to be a constant). Here are some examples: // string literally start with public string SomeProperty {get; Set;} = ...
