I'm trying the examples of the book (on my Windows 7 64bit Laptop with nVidia
graphic) but block_redux does not work.
Even the svn version does not.
The window was just white:
SwapBuffers does not "paint" into the window.
Reading "http://www.opengl.org/pipeline/article/vol003_7/" I found that I need
a "glFlush" before the SwapBuffers():
There I found this explanation:
Windowed applications that use frontbuffer rendering without ever calling
glFlush or glFinish (as they should) are likely to appear completely black,
because the rendering will sit forever in the offscreen frontbuffer. Not even
switching the DWM off is likely to fix these, given that the offscreen
frontbuffer is a requirement of the driver model itself.
Additional note:
Neither the zip file nor the SVN version did come so far.
I had to replace the value "1" for
WGL_ACCELERATION_ARB to WGL_FULL_ACCELERATION_ARB
with "1" I didn't get the pixel format error message.
