I am working on creating a 360° virtual tour where panoramic images should seamlessly integrated with a 3D model. Here’s the workflow: The user clicks a hotspot.(PRESS m key) The camera moves to the hotspot’s position in the 3D model. The view switches to a spherical panorama view where the user ca…

What are the standard techniques and considerations for accurately aligning 360° panoramic images with a 3D model at specific hotspot locations in a virtual tour? In order to perfectly align a 3d model with a panoramic image you have to know both the position and the orientation of the image in a…

I did also look into this, but didn’t come to a conclusion and hence didn’t post an answer. As an extension to the very good answer from @Antonio , I’d like to add the following: The utmost importance of replicating the exact same viewing position which the camera had when the spherical panorama was…

[image] vielzutun.ch: to use the same focal lens in your virtual Three.s camera as the physical lens Exactly, very good observation! I forgot to mention, I started setting the camera fov as 60°, but then ended up further adjusting it with the mouse scroll and a custom function until I found …

Like these demos? If that’s what you’re after, you’re gonna need a depth map to go along with your images (or if you know exaxctly the location where a photo was taken relative to the 3D models, then you can use that to make a depth map). Once you have a depth map, you can morph the image in a s…

Blockquote in order to perfectly align a 3d model with a panoramic image you have to know both the position and the orientation of the image in a common 3d coordinate space First of all thanks for going through the question and code and giving your input much appreciated. Just to confirm, when y…

Blockquote Like these demos? @trusktr Yes Exactly I want to achieve similar to this !!!

[image] vielzutun.ch: The utmost importance of replicating the exact same viewing position which the camera had when the spherical panorama was taken cannot be overstated. I saw the shadow of the tripod in a certain direction. Maybe you can “carry over” the intersection of two reference lines fr…

[image] any_post: Just to confirm, /…/ I need to position the panorama sphere at the original camera’s location (position) and rotate it to match the camera’s facing direction (orientation). That’s correct [image] any_post: also when you mention a common 3D coordinate space, do you mean …

I’ve ensured that the camera position is exactly the same as when the spherical panorama was taken. You didn’t succeed in that. I uploaded a modified image with vertical lines in it which clearly shows where the nadir of the panoramic image is: at the center of the big black circle Please change…
