I have a very specific retopo-problem.
I have a 3d scaned object and a have an image that is a photo of that object. Both, the mesh and the image is in high resolution. We cant use the mesh for our game becouse it has like 1m vertecies so i have to do a retopo of it.
On Order to do a clean retopo i have to use both, the highpoly mesh and the image as reference.
My Problem now is to figure out how to do the projection of the image to my wip lowpoly object.
I have to somehow set a camera that is the same to the camera when we took the photo.
Since i have the mesh and the image it should theroreticaly be possible to let the programm calculate the camera.
Like i could tell the programm where some points of the mesh are and where the corresponting points in the image are, and then the programm should be able to calculate the camera. (i mean line field of view, distance and so on)
And from that camera i get i could do my projection to my lowpoly model.
I hope i was able to express myself i also dont know if this is the right topic where to post this.
