Mat, could you explain me how did you dump those images?
I can explain this to you but I use Java and Java Advance imaging for producing the pictures...
For the OpenGL part, You have to use glReadPixel(x,y,width,height,format,type,pixels) function that will read the pixels of the scene and put the result in an array.. After you must use this array for producing the pictures.. I know how to do it in Java but not in C++.. but you can find a lot of examples in the archives of the forum for C++ code.
(x,y) angle inferior left of the area to read
width height the dimsension of the area
format, the element type (GL_RGB, GL_RGBA...)
type the type of data (GL_BYTE,
and pixel a byte array of the pixels read..
the size of this array (for a byte array) will be(width*height*Element type size (3 for RGB 4 for RGBA..))
Now if you work also with Java tell me I will give you the code I used for producing the pictures !!!
