You can export Blender files as ".obj" and then utilize the Wavefront OBJ Toolbox for fetching the vertices of your Blender object: https://www.mathworks.com/matlabcentral/fileexchange/27982-wavefront-obj-toolbox
% I used this free Blender object: https://free3d.com/3d-model/low-poly-racing-car-22092.html
obj = read_wobj(<filename>);
% Vertices are stored as a matrix of doubles in the obj struct
vertices = obj.vertices;
You can then use these vertices in the meshgrid after converting them to vectors.
