Blender programmatic/declarative proof of concept

[afomi]

Goal:

Create a basic example of scripting a Blender app.

[afomi]

import bpy
from random import randint


for x in range(0, 11): # X 
    for y in range(0, 11): # Y
        for z in range(0, 11): # Z
            i = randint(0, 40)
            bpy.ops.mesh.primitive_cube_add(location=(i, y * 4, z * 4))

@afomi

Bingo!

Makes me want to go back to Blender. Almost.

@theo-armour - the following .py imports the coordinates from the jsonlines file, as boxes.

next step, render lines - though was thinking about rendering them as planes instead. any thoughts?

import json
import bpy

with open("/Users/ryan/Desktop/london-office.xml.jsonl", "r") as read_file:
    for line in read_file:
        data = json.loads(line)
        # process coordinates in triplets x,y,z,x2,y2,z2,etc.
        i = 0
        coords = data["coordinates"]
        while i < len(coords):
            x = float(coords[i])
            y = float(coords[i + 1])
            z = float(coords[i + 2])
            i = i + 3
            bpy.ops.mesh.primitive_cube_add(location=(x, y, z), size=0.3)

@theo-armour - here is an early pass at lines. Some are not getting interpreted, but its a start.

[afomi]

@theo-armour - here are the lines, loaded into blender. had to iron out some array issues to connect the last coordinate and the first again.

What's next?

[theo-armour]

turning the lines into polygons https://github.com/zeffii/BlenderPythonRecipes/wiki/BMesh

@theo-armour - polygons!

[theo-armour]

@afomi

Very nice - and quickly done

I am currently working on the various attributes of a building - lat/lon etc - probably not relevant to you unless you want to to Sun and shadows.

Will have my polygons in Three.js by tomorrow. Not trivial in Three.js

BTW, I had a day-trip to Mount Diablo then ate at Momo's in Walnut Creek

[afomi]

@theo - here are the polygons split out into individual panels. (the previous one was just one large, gnarly polygon)

[theo-armour]

@afomi

Enhancing already!

Can you add a light?

Or can you show who the author of the surface is or any of its other attributes?

[afomi]

@theo-armour - anything is possible 😉

I'd prefer not to continue to expand the scope of this issue.
I did however, split out these tasks as Issues of their own.

• add a light - Render a scene that has light and shadows #15
• show the author - Display author data in Blender scene #16
