To achieve the transformative effect on elements, I utilize rotateX, rotateY, and perspective properties.
By using getBoundingClientRect(), I am able to retrieve details such as top, left, bottom, right, width, and height of an element.
Is there a method to calculate the four vertices coordinate of a (DOM element) once the image has been transformed?
Apologies for any errors in my language.

Check out image demos here:
When using Element.getBoundingClientRect, keep in mind the impact of CSS/SVG transform.If you need to determine the screen position of a transformed element's 4 corners, simply add measurer child elements to the element. Then, adjust the style of these measurer children as outlined below:
.measurer {
display: block;
width: 0;
height: 0;
position: absolute;
}
.measurer.top {
top: 0;
}
.measurer.bottom {
bottom: 0;
}
.measurer.left {
left: 0;
}
.measurer.right {
right: 0;
}
Once this is done, you can use getBoundingClientRect on the 4 measurer elements to determine their position.
