#c_sharp #directx
Написал программу на C# (квадрат из 8 точек, повороты, масштабирование, сброс). Теперь нужно переделать её под DirectX, о котором я вообще ничего не знаю... Я даже не знаю как его подключать, могли бы вы посоветовать очень простую лекцию для выполнения этого простого задания...

Подключить DX функции для создания графики можно установив пакет DirectX SDK который можно скачать с оффсайта Microsoft. А переделать под него - означает использовать в качестве функции рисования API DX'а(DirectDraw), самый банальный способ на мой взгляд и простой это написать ту же программу юзая Microsoft Visual C++, там вывод графики осуществляется по средствам DirectDraw. Это довольно обширная тема чтобы описать все этапы тут, ведь нам потребуется написать процедуру вызова окна, инициализации палитры и много чего другого, поэтому поделюсь ссылкой на ресурс который помог мне в этом разобраться. http://www.helloworld.ru/texts/comp/games/directx/ddraw/directx.htmОтвет 2
раз на С# то может надо переделать на Direct2D, а не DirectX? вот библиотека а если все таки на DirectX, то есть смысл скачать себе XNA Game Studio, там все можно сделать в 10 строчекОтвет 3
На С# есть замечательная библиотека SharpDX Основной код(Код шейдера ниже) // Copyright (c) 2010-2013 SharpDX - Alexandre Mutel // // Permission is hereby granted, free of charge, to any person obtaining a copy // of this software and associated documentation files (the "Software"), to deal // in the Software without restriction, including without limitation the rights // to use, copy, modify, merge, publish, distribute, sublicense, and/or sell // copies of the Software, and to permit persons to whom the Software is // furnished to do so, subject to the following conditions: // // The above copyright notice and this permission notice shall be included in // all copies or substantial portions of the Software. // // THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR // IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, // FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
