At first, I wasn't sure, and disinclined to find out what kind of relationship is between Noël Danjou's AMCap and the early discontinued, even gone Microsoft's AMCAP (AKA: USB 2.0 Camera). After all, they look exactly the same (includes name, interface, and most features). But gradually I began to realize that, AMCap is just a upgraded/enhanced and commercial edition of the freeware AMCAP.

Thea Render is a light-weight rendering engine combining the physics rendering and non-physics rendering, based on the GPU preview. Especially, it has a good cooperation with the commonly used industry software by architects, like SketchUp.

Lumion is a real-time 3D architecture visualization software, which features the real-time display, can obtain the final effects without having to rending first.

In 2010, I mistakenly chose one of partitions on my mobile hard drive when I was using Ghost backup file (GHO) to recovery the system partition (C volume), which led to a devastating partition-level of data loss. Since then, I have been sealing this entire hard disk all the time. Until 2017's first half, I finally had enough time and patience to restore most of the data inside. And among these recovered files, I accidentally discovered a very handy and practical software - 5D PDF Creator, which was published as early as 2008, and has been discontinued and gone from Internet for many years.

By modifying the environment variables of system or software to save a variety of commonly used temporary folders (Temp, IE Cache, Download folder, for example) to the virtual hard disk (RAM drive), we can effectively improve the file reading/writing speed and software running speed. And in fact, it can also reduce the reading/writing times of physical disk so as to prolong its service life to some extent.
