SDL使用SDL_Surface和SDL_Texture这2种结构绘图到屏幕。SDL_Surface包含了一个像素集合(pixels成员),它使用软件渲染(非GPU);SDL_Textur可使用硬件加速器。使用SDL_Texture的示例程序: #include "SDL.h" class Game2{public: Game2():m_pWindow(NULL),m_pRenderer(NULL), m_bRunning(false){}; ~Game2(){...

这代表GPU上的一种纹理。通过上传像素到这个纹理上来填充每一帧,在窗口上绘制这种纹理,最后翻转这张图片到屏幕上。SDL_TEXTUREACCESS_STREAMING这个值告诉SDL,这个纹理的内容经常会经常发生改变。 在你的程序绘制到屏幕之前你很可能需要一个SDL_Surface,接着调用SDL_Flip()函数来让它在屏幕上显示。现在你可以创建一个...
