How to get projected depth values from camera toolbar while displaying a 3D mesh.

Hi all, Suppose I have a 3D triangular mesh with some 'V' vertices and 'F' faces, 'V' contains 'XYZ' elements of the vertices, now using this 'Toolbox Graph', I am able to view my mesh nicely , by plot_mesh(V,F). https://in.mathworks.com/matlabcentral/fileexchange/5355-toolbox-graph Now I know that it uses camera toolbar of matlab to plot and show things , I can maximize , rotate etc and can set the view matrix manually and get a desired projective or orthographic view of the object.

I am still struggling on how to get the visible projection of the object in form of a depth image, More specifically something like raw depth map of the object (like simulating kinect [do not want actual simulation and noise modelling]), when viewed from an angle.

Any help will be highly appreciated. Thanks :)

Hi @Gaurav. My 3D Rendering Toolbox on File Exchange will easily handle this. For example, you can see the toolbox generating a depth map in the figure below. It does, however, only currently handle perspective projection.
