I use Blender about once a year, and I use the API even less frequently. Recently, I wanted to create an animation of a hardware stack on a computer I used decades ago. Bing Chat was very helpful in getting me started. There are some formatting errors in this transcript, but you get the idea. Write me a blender script that displays a computer's stack as a series of boxes, with pointers to the base of the stack and the top of the stack. Sure, here’s a simple script that creates a stack visualization in Blender using boxes. This script doesn’t actually represent the computer’s memory stack, but it gives a visual representation of a stack data structure. import bpy # Clear all mesh objectsbpy.ops.object.select_all(action='DESELECT') bpy.ops.object.select_by_type(type='MESH') bpy.ops.object.delete() # Parameters for stack visualizationstack_size = 10box_size = 1box_distance = 1.2# Create stack boxesfori inrange(stack_size): bpy.ops.mesh.primitive_cube_add( size=box_size, location=(0, 0, i * box_distance) ) # Create pointersbpy.ops.mesh.primitive_cone_add( vertices=4, radius1=0.2, depth=1, location=(2, 0, 0) # Base pointer) bpy.ops.mesh.primitive_cone_add( vertices=4, radius1=0.2, depth=1, location=(2, 0, (stack_size - 1) * box_distance) # Top pointer) This script first clears all existing mesh objects in the scene. Then it creates a series of boxes stacked on top of each other to represent the stack. Finally, it adds two cones to represent pointers to the base and top of the stack. Please note that you need to have Blender’s Python API (bpy) installed and this script should be run in Blender’s scripting environment. Also remember that this is a very basic representation and doesn’t interact with an actual computer’s memory stack. Thanks. Improve the script by turning it into a function called setup_stack() and call the function. Scale the blocks by (1.0,3.0, 1.0) and orient the camera to view the entire stack. Sure, here’s the improved script: import bpy def setup_stack(): # Clear all mesh objectsbpy.ops.object.select_all(action='DESELECT') bpy.ops.object.select_by_type(type='MESH') bpy.ops.object.delete() # Parameters for stack visualizationstack_size = 10box_size = 1box_distance = 1.2# Create stack boxesfori inrange(stack_size): bpy.ops.mesh.primitive_cube_add( size=box_size, location=(0, 0, i * box_distance) ) bpy.context.object.scale = (1.0, 3.0, 1.0) # Create pointersbpy.ops.mesh.primitive_cone_add( vertices=4, radius1=0.2, depth=1, location=(2, 0, 0) # Base pointer) bpy.ops.mesh.primitive_cone_add( vertices=4, radius1=0.2, depth=1, location=(2, 0, (stack_size - 1) * box_distance) # Top pointer) # Orient the camera to view the complete stackcam = bpy.data.cameras.new("Camera") cam_obj = bpy.data.objects.new("Camera", cam) bpy.context.collection.objects.link(cam_obj) cam_obj.location = (10.0, -10.0, (stack_size / 2) * box_distance) cam_obj.rotation_euler = (1.0472, 0, 0.785398) # 60 degrees pitch, 45 degrees yawbpy.context.scene.camera = cam_obj # Call the function to setup the stacksetup_stack() This script now includes a function setup_stack() that sets up the stack visualization. The blocks are scaled by (1.0, 3.0, 1.0) as per your request. The camera is also oriented to view the complete stack. Thanks. Improve the script further by coloring the blocks light blue and giving them a matt texture. Sure, here’s the updated script: import bpy def setup_stack(): # Clear all mesh objectsbpy.ops.object.select_all(action='DESELECT') bpy.ops.object.select_by_type(type='MESH') bpy.ops.object.delete() # Parameters for stack visualizationstack_size = 10box_size = 1box_distance = 1.2# Create stack boxesfori inrange(stack_size): bpy.ops.mesh.primitive_cube_add( size=box_size, location=(0, 0, i * box_distance) ) bpy.context.object.scale = (3.0, 1.0, 0.5) # Set the color to a light blue with a matt texturemat = bpy.data.materials.new(name="Mat") mat.diffuse_color = (0.5, 0.5, 1.0, 1) # Light bluemat.use_nodes = Truebsdf = mat.node_tree.nodes["Principled BSDF"] bsdf.inputs['Roughness'].default_value = 1# Matt texturebpy.context.object.data.materials.append(mat) # Create pointersbpy.ops.mesh.primitive_cone_add( vertices=4, radius1=0.2, depth=1, location=(2, 0, 0) # Base pointer) bpy.ops.mesh.primitive_cone_add( vertices=4, radius1=0.2, depth=1, location=(2, 0, (stack_size - 1) * box_distance) # Top pointer) # Orient the camera to view the complete stackcam = bpy.data.cameras.new("Camera") cam_obj = bpy.data.objects.new("Camera", cam) bpy.context.collection.objects.link(cam_obj) cam_obj.location = (10.0, -10.0, (stack_size / 2) * box_distance) cam_obj.rotation_euler = (1.0472, 0, 0.785398) # 60 degrees pitch, 45 degrees yawbpy.context.scene.camera = cam_obj # Call the function to setup the stacksetup_stack() This script now includes a function setup_stack() that sets up the stack visualization.

The marketing pressure you feel fromTelcos to drop your landline, and buy smartphones, tablets and 4G modems for your laptop is a result of the FCC's decision to encourage innovation by not regulating the technology and services (beyond requiring some basic 911 services.) The market is a potential goldmine compared to landline services. You can't complain about companies selling you service or bandwidth that isn't available because there's no one regulating the offerings. Market mechanisms don't work either, since none of the carriers have the capacity to offer quality service and broad coverage, and they've forced punitive contracts on us to prevent market mechanisms from working.
