glutReshapeFunc(void(*func)(intw,inth))指示在调整窗口大小时应采取的操作。 glutKeyboardFunc(void(*func)(unsigned charkey,intx,inty))和glutMouseFunc(void(*func)(intbutton,intstate,intx,inty))允许您链接键盘键或按下或释放键或鼠标按钮时调用的例程的鼠标按钮。 当鼠标按键被移动时,glutMotionFunc(void...
int state, int x, int y ) { //鼠标按下事件 if( button == GLUT_LEFT_BUTTON && state == GLUT_DOWN ) { numPoints++; if( numPoints == 1 ) { // user is placing the starting point for the ray S = Vector2( x, (600 - y) ); rays.clear(); EndPt = Vector2( x, 600...
voidGLUTBackendInit(intargc,char**argv);boolGLUTBackendCreateWindow(unsignedintWidth,unsignedintHeight,unsignedintbpp,boolisFullScreen,constchar*pTitle); GLUT的很多变量生命的代码全都移到了一个"GLUT backend"组件中,这样就可以用上面的函数更加简单方便的来初始化GLUT以及创建一个窗口。 (glut_backend.h:28)...
The most serious issue that we face when doing ray tracing in its purest form, is that most of the photons emitted by a light source actually never reach our eye. When reflecting a photon on a surface, we must decide where that photon is going to continue its path through the scene. A...

The PFD_DRAW_TO_BITMAP pixel format descriptor flag allows OpenGL™ applications to render on a Microsoft® Windows® device-independent bitmap (DIB). The resulting DIB can be manipulated to the full extent using the commands in the Windows graphics device interface (GDI). This article exp...
After the blurring passes are complete, the blur results are combined with the full color texture of the scene to produce the final results. In Listing 9.28, notice that the final shader samples form two textures: the original full color texture and the blurred version of the bright pass. Th...
5多通道绘制技术 •多通道绘制技术的应用模式 –独立模式：每一通道的绘制都是独立的，后面的绘制不使用前面绘制的结果,各次绘制没有顺序要求.一般是多次绘制的结果按照一定的逻辑叠加或融合形成最后的图像.这是最简单的多通道绘制模式.例如多通道纹理映射就是这种模式.–关联模式：后面的绘制要使用前面的绘制设置的...
Given these limitations, I’ve decided to use Skia as the backend graphics engine in Alcinoe while continuing to use the legacy Delphi canvas (TCanvasGPU) for rendering on the main form surface. The exception is on Windows, where we use Skia for both the backend and the main form surface...
