(IShockwaveFlash是一个IViewObject) 把DC的像素数据拷贝到D3D的Texture上...中间涉及像素格式的内存操作, 需要明白图像数据的内存格式. 半透明支持(可选): 如果不需要半透明支持的话, 其实可以直接OleDraw到Texture的DC上, 不用再多一次拷贝...但是有时候不得不用(像UI), 可以这参考Transparent Flash Control in ...

rayshader is an open source package for producing 2D and 3D data visualizations in R. rayshader uses elevation data in a base R matrix and a combination of raytracing, spherical texture mapping, overlays, and ambient occlusion to generate beautiful topographic 2D and 3D maps. In addition to map...
opengl、framebuffer、render-to-texture、depth-buffer、deferred-rendering 我在我的游戏中使用了延迟的渲染器。因此,第一个渲染过程是创建反照率和正常缓冲区,使用多个渲染目标并填充深度缓冲区。所有这些缓冲区实际上都是纹理。 现在我想从其他渲染过程访问深度缓冲区,从而访问其他帧缓冲区,而不改变深度纹理。我只想...
