Is it possible to overlay a 2D image over a pointcloud in RViz2
Let's say I have a 2D image, taken from a video. Let's say I also have a Pointcloud, generated by a radar sensor. Would it be possible to project this 2D image over the Pointcloud, such that the Pointcloud acts like a 3D model (in which the points are vertices of said model) and the image acts as the texture for the model? If it is possible, is there anything online that could tell me how to do it?
EDIT: I also saw a question ( https://answers.ros.org/question/2185... ) and the top answer said something about being able to use an image to texture a Mesh object. Would it be possible to use the radar information I used to create a Pointcloud in order to create a Mesh? The radar data is represented as polar coordinates, which we then convert to cartesian to generate the Pointcloud)
