Blender 2.92.0 - Using Blender's filebrowser with Python -

Using Blender’s filebrowser with Python というのを見つけた。

そのままBlenderから実行して、確かにファイル名やフルパスが得られることを確認した。これを、自分のスクリプトに組み込めばファイルの指定が自在にできるようになって便利だ。試しに、今やっている、位置データのCSVファイルを読み込んでObjectにアニメーションをつけるPythonスクリプト、に組み込んでみる。下が組み込む前のスクリプトで、ファイル名を決め打ちしている。

import bpy
from mathutils import *
from math import *
from bpy.props import *
import os
import time

# Init
position_vector = []

# Open file
file = open("D:\\part3-002_Camera_tr_Track_arr1.csv", "r")

obj = bpy.context.object

temporalScale=bpy.context.scene.render.fps

for line in file:
    # Split line at ";"
    line = line.replace("\n","")
    locRotArray = line.split(",")
    #for lrt in locRotArray:
    obj.location = (float(locRotArray[1]), float(locRotArray[2]), float(locRotArray[3]))
    #time = float(locRotArray[0])*temporalScale
    #time = float(locRotArray[0])*0.0166666666666667
    time = float(locRotArray[0])
    obj.keyframe_insert(data_path="location", frame=time)

import bpy

from mathutils import *

from math import *

from bpy.props import *

import os

import time

# Init

position_vector = []

# Open file

file = open("D:\\part3-002_Camera_tr_Track_arr1.csv", "r")

obj = bpy.context.object

temporalScale=bpy.context.scene.render.fps

for line in file:

# Split line at ";"

line = line.replace("\n","")

locRotArray = line.split(",")

#for lrt in locRotArray:

obj.location = (float(locRotArray[1]), float(locRotArray[2]), float(locRotArray[3]))

#time = float(locRotArray[0])*temporalScale

#time = float(locRotArray[0])*0.0166666666666667

time = float(locRotArray[0])

obj.keyframe_insert(data_path="location", frame=time)

これが、組み込んだ後のスクリプトだ。 [crayon-673a7c26ed4
