MATLAB: How to create a volume using x,y,z co-ordinates for use in isosurface & isocaps function

Question

Hi I have x,y,z co-ordinates – which you can visualise with " figure, stem3(xI, yI, zI, 'MarkerFaceColor', 'g'); " , if you open my attached .mat file

I want to create a volume from this, compatible with the the matlab functions isosurface and isocaps

https://uk.mathworks.com/help/matlab/visualize/visualizing-volume-data.html#responsive_offcanvas

the eventual aim is to build a wavefront object (using this function https://uk.mathworks.com/matlabcentral/fileexchange/27982-wavefront-obj-toolbox

How would I go about making (interpolating?) this volume matrix, assuming that the volume starts from z=0 to z=n ?

Answer 1

Already you have a surface there......

surf(xI, yI, zI) 
shading interp 
colorbar
