[Video about image to 3d-city generator([https://www.youtube.com/watch?v=y0nsXiI\_I9c](https://www.youtube.com/watch?v=y0nsXiI_I9c))  
I am interested in the application, that he shows here and he shares it for free through github (link in video-description).

In his video i saw, he opened the .pde-file from it in processing to manipulate and render the cities.

So i grabbed the latest processing version and tried to run it there.

bot it creates only a white window and this error-log:

What is used instead of  
`void processing.core.PVector.add(processing.core.PVector)`  
now?

Now i found a topic, that says, that a tool called “objloader” is not compatiple with recent processing versions any more and it´s used for the city-renderer, i´m talking about here.

Do you know an alternative tool to plugin for replacing “objloader”?

see [loadShape() / Reference / Processing.org](https://processing.org/reference/loadShape_.html)

also, this is not very advanced for more complex obj’s imho

Here is my version of the city generator:  
[my repository](https://github.com/Drachenbauer/yoyleCityWords-master)

actually i get this error:

can you help me fix that?

Finally seems solved. i see no more error message and a window with green grass and blue sky.

Now i have a screenshot of the city, made from my kite-image:
