# RGBD Field of View and mesh intersection surface

I'm trying to get the intersection surface area between an RGBD sensor FOV and a mesh model since I want to use these surfaces to fasten the development of reconstruction algorithm and then use the algorithm and apply it in Gazebo simulation

It is similar to the intersection surface of two models as it is shown in the following image link: image link , but instead of the sphere, I have the FOV (Quadrahedron shape) and instead of the cube model, I have another model shape

The blue part of the cube surface shown in the third part of the image is the intersection surface needed to be found

is there a function in PCL or other libraries that can find the intersection surface between a RGBD camera FOV and a mesh model? Could someone point me towards any related things?

Can you illustrate this in a diagram ? What do you mean ?
