I am thinking of a small python project, but I’m rusty (haven’t blended in a year or two). Here’s the idea. I start with a square mesh. I subdivide it a few times so there are, lets say 1089 vertices. Now I want to import a text file (using python) in which there is a sequence of numbers indicating how far to extrude these vertices upwards (or downward for negative numbers). The order of these numbers could correspond to the sequence in which the vertices are extruded. Question: does the python interface in Blender have the capacity to access vertices of a mesh like this, and is there a means using python in blender to access an external file. My assumption is yes to both (how else would other python importers work). This task seems really easy, but if anyone has a hint of how to get started, I’d appreciate it.
