Yes, positions are relative to parents. I wrote a script for Blender that set object hierarchy and set object positions:
import bpy
scale = 1
file = open("E:\\_Projects\\WebGL\\re\\re1-animaitons-webgl10-ts\\project_files\\CHAR11_01.ANI", "r")
lines = file.readlines() # get all lines
current_file_line = 0;
amount = int(lines[current_file_line]) # get an amount of bones
current_file_line += 1
# Create an array of object, scale and apply rotations
whole_object = []
for i in range(amount):
whole_object.append(bpy.data.objects["Object_" + str(i) + ".002"])
whole_object[i].scale = (scale, scale, scale)
whole_object[i].select = True
bpy.ops.object.transform_apply(location=False, rotation=True, scale=False)
# Set parents
for i in range(amount):
line_parts = lines[current_file_line].split()
current_file_line += 1
bone_amount = int(line_parts[0])
for j in range(bone_amount):
index = int(line_parts[j+1])
whole_object[index].parent = whole_object[i]
# Set positions
start_index = amount+1
for i in range(amount):
coords = lines[start_index + i].split()
x = float(coords[0])
y = float(coords[1])
z = float(coords[2])
print(x, y, z)
whole_object[i].location = (x, y, z)
