Cannot add 'custom' model with addMesh() as the only two options are 'polygon' and 'cylinder'

Hi,

for my dissertation I need to place custom models in a uav scenario to collect LIDAR data. In the documentation it says that it is possible to add custom models by supplying the vertice list and the vertice connectivity list using addMesh(scene,'custom',{vertices,faces}) but when running the code an error pops up saying

Expected type to match one of these values:

'polygon', 'cylinder'

The input, 'custom', did not match any of the valid values.

Does the package not support custom models anymore? I checked the code and it only includes the two options mentioned above, is there a way to get an older version of the code that allows custom models?

Thank you.

Hi, Gianluca,

What MATLAB version are you using? "custom" option is added in R2021a.

Thanks,

Hi Jianxin,

Thanks for the speedy reply, issue solved. I would like to suggest adding support to simply provide a .stl file in the addMesh() instead of having to extract the vertices and connectivity list for easier use using custom models. I am assuming this is easier when using the Simulink Unreal Engine simulation but for mac users unfortunately this is not an option.

Thank you,

Gianluca

Starting from R2021a, user can use stlread to import stl files into MATLAB and use addMesh custom option to add the model into uavScenario. See code sample below:

scene = uavScenario;
stltri = stlread("multirotor.stl");
addMesh(scene, "custom", {stltri.Points, stltri.ConnectivityList}, [1, 0, 0]);
show3D(scene)
