Detailed Description

Display for windows using Direct3D.

Direct3D is part of the DirectX API available under Windows operating systems.

Warning
Requires DirectX9 SDK to compile and DirectX9 DLLs to run.

The example below shows how to display an image with this video device.

#include <visp/vpConfig.h>
#include <visp/vpImageIo.h>
#include <visp/vpDisplayD3D.h>
int main()
{
#if defined(VISP_HAVE_D3D9)
vpImage<unsigned char> I; // Grey level image
// Read an image in PGM P5 format
vpImageIo::read(I, "C:/temp/ViSP-images/Klimt/Klimt.pgm");
// Initialize the display with the image I. Display and image are
// now link together.
d.init(I);
// Specify the window location
// Set the display window title
vpDisplay::setTitle(I, "My Direct 3D display");
// Set the display background with image I content
// Draw a red rectangle in the display overlay (foreground)
vpImagePoint topLeftCorner;
topLeftCorner.set_i(10);
topLeftCorner.set_j(20);
vpDisplay::displayRectangle(I, topLeftCorner, 100, 20, vpColor::red, true);
// Flush the foreground and background display
// Wait for a click in the display window
#endif
}
