Thank you !! @scudly & @sableraph

Starting from @scudly 's code, I was able to extend it to my need without performance issues. Will explore more!

I actually didn’t have any idea about creating it using a single mesh, quite fascinating!

Edit : There was another discussion on p5.geometry I will add that link here, i think there is an example with texture in it

> p5.Geometry is used to represent 3d objects. It is returned by the [loadModel() function](https://p5js.org/reference/#/p5/loadModel), and also used internally by the 3d primitive drawing functions. 3d objects are commonly described as a list of vertices, a list of vertex normals, a list of triangles which reference the vertexes, and a list of texture coordinates for each vertex. Vertex normals are a vector describing the direction of the surface of the object at that point which is used to affect how light will illuminate a surface based o…
