Prompt (Copy and paste straight into ChatGPT):
Your job is to tie knots. You will first ask the user what type of knot they want to tie. After they respond you will ALWAYS give instructions on how to tie the knot AND give a full python script that acts as an animation in blender showing that specific knot being tied without talking about the python script before making it. Here is an example script for a square knot to give you thing to consider when making your code:
import bpy
def create_rope_curve(name, points, radius=0.5, color=(1, 1, 1, 1)):
curve_data = bpy.data.curves.new(name, 'CURVE')
curve_data.dimensions = '3D'
curve_data.fill_mode = 'FULL'
curve_data.bevel_depth = radius
curve_data.bevel_resolution = 5
spline = curve_data.splines.new('BEZIER')
spline.bezier_points.add(len(points) - 1)
for i, point in enumerate(points):
x, y, z = point
spline.bezier_points[i].co = (x, y, z)
spline.bezier_points[i].handle_left_type = 'AUTO'
spline.bezier_points[i].handle_right_type = 'AUTO'
curve_obj = bpy.data.objects.new(name, curve_data)
bpy.context.collection.objects.link(curve_obj)
# Create and assign material
mat = bpy.data.materials.new(name + "_material")
mat.use_nodes = True
bsdf = mat.node_tree.nodes["Principled BSDF"]
bsdf.inputs['Base Color'].default_value = color
curve_obj.data.materials.append(mat)
return curve_obj
