I like to implement some length measurement by selecting 2 points on objects and using raycasting to get the points. The basics are working but i have a annoying offset between real mouseposition and the shown intersection. This picture explain it the best: [Screenshot_20210421_215305] This is m…

hi this is to fix mouse coord when the renderer (and its canvas) has a lower size then fullwidth var rect = renderer.domElement.getBoundingClientRect(); mouse.x = ( ( event.clientX - rect.left ) / ( rect.right - rect.left ) ) * 2 - 1; mouse.y = - ( ( event.clientY - rect.top ) / ( rect.bottom - re…

Have you tried doing a raycast from a dummy object that has a slightly different position relative to the camera?

im not sure what you mean with raycast “from” but it doesnt matter what kind of objects i take: [Screenshot_20210425_175019] [Screenshot_20210425_175045] [Screenshot_20210425_175121]

I have done some testing, and for me the ray cast point is positioned at the point of the mouse cursor. It is however off when the canvas is not completely covering the screen. (in my case the use of the Css3DRenderer caused setting a ‘perspective’ style element, causing some white space next to th…

Have you checked if the values of rect are correct? Which element is triggering the pointermove event? The canvas? As far as I can tell your canvas covers the hole screen right? Then this should actually work mouse.x = ( event.clientX / window.innerWidth ) * 2 - 1; mouse.y = - ( event.clientY / w…

Hi, did you find any solution? I am facing the same issue but in AR, tried all possible methods. Even my canvas is covering the entire screen/camera.
