Blender 3D and python scripting - part 005.

In this tutorial I will recreate the same box but with a more complex source code.

In the previous tutorial I used the same source code several times...

    obj = bpy.ops.mesh.primitive_plane_add(size=2, 
    calc_uvs=True, 
    enter_editmode=False, 
    align='CURSOR', 
    location=location, 
    rotation=(0, 0, 0), 
    scale=(0,0,0)
    )
    
    # rename the object
    bpy.context.object.name = obj_name
    # return the object reference
    return bpy.context.object

It is easier to understand the steps taken and then move on to optimizing them in complex forms.

Obviously a presentation of the source code in this tutorial will show you the differences.

I will add that the source code does not include scalar transformations and is limited to a box with size 1.

import bpy

def create_plane_XYZ(loc, obj_name):
    #define the pi 
    pi = 3.1415926
    # this is a definition like a tuple
    rot = (0,0,0)
    # need to convert it to a list in order to add new values
    rot_list = list(rot)
    # this ang variable will rotate obj to the 90-degree angle 
    ang = -90*(pi/180)
    ang_inc = 45*(pi/180)
    if loc[0] < 0:
        rot_list[1]=ang

    if loc[0] > 0: 
        rot_list[1]=ang

    if loc[1] < 0:
        rot_list[0]=ang
        
    if loc[1] > 0: 
        rot_list[0]=ang
    # this check if the two value from position of plane is not zero
    if loc[1] != loc[2] != 0: 
        rot_list[0]=ang_inc
    # this convert a list back to tuple 
    rot=tuple(rot_list)
    # this create the plane 
    obj = bpy.ops.mesh.primitive_plane_add(size=2, 
    calc_uvs=True, 
    enter_editmode=False, 
    align='CURSOR', 
    location=loc, 
    rotation= rot, 
    scale=(0,0,0)
    )
    # rename the object
    bpy.context.object.name = obj_name
    # return the object reference
    return bpy.context.object

# this will create a plane on X and translate with -1 on Y 
planeX001 = create_plane_XYZ((0,-1,0), "Plane-X")
# this will create a plane on X and translate with 1 on Y 
planeX002 = create_plane_XYZ((0,1,0), "Plane+X")
# this will create a plane on Y and translate with -1 on X 
planeY001 = create_plane_XYZ((-1,0,0), "Plane-Y")
# this will create a plane on X and translate with 1 on Y 
planeY002 = create_plane_XYZ((1,0,0), "Plane+Y")
# this will create a plane with 45 degree because two value on tuple is not zero
planeZ001 = create_plane_XYZ((0,-0.25,1.66), "Plane-Y+Z")
