Experience of learning VTK

Now start to learn VTK, what can not yet.

simple view, learning VTK is far more promising than learning OpenGL.

main is feeling VTK is open source packages, which have written a lot of the underlying function, data structure and data organization and relative to our own writing function rich and robust.

On Windows, VTK installation is complicated. Because at present is not very familiar with, will not write temporarily. I haven’t learned how to set the right variables.

I’m sorry.

VTK, possibly the Visualization Toolkit If you want to learn it well, consult two books

VTK User’s Guide and VTK tool kit. It’s available on its official website.

Open source stuff is really good.

Or, an application log on a machine running Windows Vista or Windows Server 2008 records an error similar to the following:
Log name: application

why
The above error occurred because the Microsoft Certificate Trust List publisher certificate has expired. A copy of the CTL whose signature certificate has expired exists in the CryptnetUrlCache folder.
In addition, the event ID 4107 May be logged as a “data invalid” error rather than a “Certificate that is not valid when verified against the current system clock or timestamp in the signature file” error.
