.What will be the position of viewport to maintain same relativeplacement as in window? [5+5=10]

The position of the viewport to maintain the same relative placement as in the window can be achieved by following these steps:

1. Identify the Window: The window is the area in the world coordinate system where the picture is defined.

2. Identify the Viewport: The viewport is the area on the screen where the picture will be displayed.

3. Set the Window and Viewport: To maintain the same relative placement, the window and viewport need to be set to the same position. This means that the lower left corner and the upper right corner of the window should match with the viewport.

4. Transformation: The process of maintaining the same relative placement is called window-to-viewport transformation. This transformation maps a portion of a world window into a viewport.

5. Maintain Aspect Ratio: To avoid distortion, the aspect ratio of the window should be the same as the viewport. The aspect ratio is the ratio of the width to the height.

6. Scaling: If the window and viewport are not the same size, scaling may be necessary. This can be done by multiplying the window coordinates by the ratio of the viewport size to the window size.

7. Translation: After scaling, the lower left corner of the window may not coincide with the lower left corner of the viewport. In this case, translation is necessary. This can be done by subtracting the window coordinates from the viewport coordinates.

By following these steps, the position of the viewport can be set to maintain the same relative placement as in the window.

The question seems to be incomplete. Could you please provide more details or context? The position of the viewport to maintain the same relative placement as in the window depends on several factors such as the size of the window, the size of the viewport, and the specific requirements of the application.

However, in general, to maintain the same relative placement, the viewport should be positioned in the same location as the window. This means that if the window is centered on the screen, the viewport should also be centered. If the window is positioned in the top left corner of the screen, the viewport should also be positioned in the top left corner.

The size of the viewport should also match the size of the window. If the window is larger than the viewport, the viewport will only show a portion of the window's content. If the viewport is larger than the window, some of the viewport's area will be wasted because it won't display any content.

Here are the steps to position the viewport:

1. Determine the position of the window on the screen.
2. Position the viewport in the same location.
3. Adjust the size of the viewport to match the size of the window.
4. Test the application to ensure that the viewport is displaying the window's content correctly.
5. Make any necessary adjustments to the viewport's position or size.

Remember, the exact steps may vary depending on the specific requirements of your application.
