  1. Half Vector & Eye Vector

    What is Eye vector and half vector? // calculate half angle vector float3 eyeVec = float3(0.0, 0.0, 1.0); float3 halfVec = normalize(lightVec + eyeVec);
  2. The data member has its scope, while it must be in the class scope. Unexpectedly, the data member lose its data or value out of the member functions' scope while debugging. I wonder the cause of it. Thanks in advance.
  3. Array Question

    how to determine which row and column is 14 in in the m x n 2D-Array?
  4. I want to determine which UI_Scheme is in use. Because the winXP window height of caption bar is very different form win2000/win9x window, in detail it is a little larger.
  5. I'm in search of a website on 2D Effects, such as sine curve dithering effect. But after a few hours, I have nothing. Thanks in advance.
  6. Thanks everybody. But these are usage! I wonder the implementation related to the compiler.
  7. Encapsulating WinAPI in a class

    I think Message Cracker and Control Macro is very good.
  8. In fact, I meant the problem as follow: #define _WIN32_WINNT 0x0500 // (1) #include <windows.h> // (2) if I eliminate the (1), the information "e:\MS Net Station\Jeffery Win\TimedMsgBox\TimedMsgBox.cpp(174): error C2065: 'CreateTimerQueueTimer' : undeclared identifier " occurs. The explaination of it is not detail, I wonder more. I'm interested in the concept fo processor macro. Is any description on it?
  9. I wonder the concept of macro, would you like to give me any materails, information or resource?
