### *Example Input Text:*

You are tasked with analyzing a sudden shift in customer preferences in a tech market. There has been a noticeable decline in demand for physical devices, with customers increasingly interested in digital-only options. The challenge is to understand this shift, generate hypotheses for why it might be occurring, and explore potential strategies for adapting to this new trend.

---

### *Processed Output with System 1 and System 2 Thinking:*

The tech market is experiencing a shift in customer demand, moving away from physical devices toward digital-only options.

[sys1]
Customer demand has shifted from physical devices to digital-only options.
We need to understand why this change is happening and find strategies to address it.
Key factors may include cost, convenience, and technological trends.
[end sys1]

[sys2]
**2.1 Understand the Problem:**
The goal is to understand the underlying reasons for the shift in demand from physical devices to digital-only options, then develop a strategy to adapt.

*Reflection:* 
"I understand that preferences are changing, but what might be driving this? Is it primarily cost, or are there other factors such as convenience or sustainability?"

*Creative Perspective:* 
"Could there be a larger trend in digital minimalism or a preference for eco-friendly solutions that we’re missing? What unseen motivations might explain this shift?"

**2.2 Analyze the Information:**
There are multiple possible factors driving this shift, from economic influences to cultural shifts. It’s essential to isolate each factor and understand its impact.

*Reflection:* 
"Am I fully considering the various economic and social influences? Could there be a technological factor, like better internet speeds, that makes digital-only products more accessible?"

*Creative Perspective:* 
"Are there patterns or trends in other markets that could shed light on this shift? Could this be part of a larger trend toward virtual experiences?"

**2.3 Generate Hypotheses:**
1. Customers prefer digital options due to lower costs. (Confidence: 0.8, Creative: 0.4)
2. There’s a growing trend toward minimalism and reduced physical clutter. (Confidence: 0.7, Creative: 0.7)
3. Digital products offer greater flexibility and ease of use. (Confidence: 0.6, Creative: 0.6)
4. Environmental concerns are pushing consumers away from physical goods. (Confidence: 0.6, Creative: 0.8)
5. Advances in tech make digital-only options more functional. (Confidence: 0.8, Creative: 0.5)
6. Pandemic-era remote work increased demand for digital solutions. (Confidence: 0.7, Creative: 0.6)
7. Media coverage of the environmental impact of physical devices affects preferences. (Confidence: 0.5, Creative: 0.7)
8. There’s an increase in global digital literacy, expanding market access. (Confidence: 0.6, Creative: 0.6)
9. Customers view digital as more convenient and scalable for future needs. (Confidence: 0.7, Creative: 0.5)
10. Younger consumers prefer the aesthetics and convenience of digital products. (Confidence: 0.6, Creative: 0.6)

*Reflection:* 
"Have I considered all possible influences? Are there any surprising factors that could explain this shift?"

*Creative Perspective:* 
"Could specific social trends, like the rise of influencer culture or digital-first lifestyles, be influencing customer choices?"

**2.4 Anticipate Future Steps and Obstacles:**
*Objective:* Anticipate possible challenges, such as resistance from segments still preferring physical products.

*Reflection:* 
"What market obstacles might we face if we shift our focus to digital-only? Are there sub-segments that still prioritize physical products?"

*Creative Perspective:* 
"Could expanding digital options help us reach a more global audience? Are there emerging trends that we could leverage in our strategy?"

[end sys2]

[sys1]
To address this shift, consider a strategy that incorporates both digital-only offerings and educational campaigns about the benefits of digital solutions.
Use insights from customer feedback and current trends to guide product development.
Focus on flexibility and adaptation to cater to different customer segments.

Q:

Exporting (bullet) collision shapes

I'm writing a scene exporter from blender to a format to be used by a game. I need to be able to export physics information the game needs, mainly the collision shape of every object (either the one set in Blender Render or Blender Game but the latter is better).
I cannot seem to find anywhere that the collision shape is available to python. I've seen references to PhysicsConstraints.exportBulletFile() but this appears to be under the bge module, which as far as I can tell, is not accessible by exporter scripts. Is there any way to determine the details of a shape (rotation and scale, width, height, depth for box or radius and height for cylinder, vertices for convex hull, etc...)?

A:

Finding the parameters necessary to generate such a shape should be possible with python.
From the wiki:

The Shape setting determines the collision shape of the object. The
  following shapes are available:
Primitive shapes - these are best in terms of memory/performance but don't necessarily reflect the actual shape of the object. They're
  calculated based on the object's bounding box. The center of gravity
  is always in the middle for now.

Box: The size per axis is calculated from the bounding box
Sphere: The radius is the largest axis of the bounding box
Capsule: This points up the Z-Axis.
Cylinder: This points up the Z-Axis. The height is taken from the z-axis, while the radius is the larger of the x/y-axes.
Cone: This points up the Z-Axis. The height is taken from the z-axis, while the radius is the larger of the x/y-axes. 

'Mesh based shapes' - these are calculated based on the geometry
  of the object so they are a better representation of the object. The
  center of gravity for these shapes is the object origin.

Convex Hull: Convex approximation of the object, has good performance and stability.
Mesh: Allows to simulate concave objects, but is rather slow and unstable.

To build these shapes using the UI:
Box:

Select the target object and press CtrlShiftAltC > Origin to goemetry, and then press F6 and select bounds center.
With the target object selected, press ShiftS> Cursor to selected to move the cursor to the objects origin.
Add a cube to be the bounding box. It will automatically be centered at the 3D cursor, which is snapped to the target object's origin point.
Copy the Dimension and Rotation values from the target object to the bounding cube. These values are located on the Properties region (N in the 3D view):

You can quickly copy and paste values by hovering over the number field and pressing CtrlC/CtrlV accordingly.
Since this process of copying and pasting the values of each channel can be a bit tedious, you can use a quick bit of python to do this for you:
import bpy

active = bpy.context.active_object
selected = bpy.context.selected_objects

for obj in selected:
    obj.dimensions = active.dimensions

This copies the dimensions from the active object to the selected objects.
Parent the bounding box to the target object so the relative location, rotation, and scale is kept the same. You can also set the bounding cube's Draw type to Wire in Properties > Object > Display > Maximum Draw Type.

Sphere

Do steps 1 to 3  from the Box instructions, adding a sphere instead of a cube. 
Copy only the largest dimension value from the target into all three dimensions of the sphere.
Do step 3 of the instructions for Box (Parent the bounding mesh and set the draw type to wire)

Cylinder

Do steps 1 to 3  from the Box instructions, adding a cylinder instead of a cube.
Copy the largest dimension value of the target excluding the Z axis, so the value of either X or Y into both the X and Y dimensions of the Cylinder.
Copy the Z dimension value of the target to the Cylinder.
Do step 3 of the instructions for Box (Parent the bounding mesh and set the draw type to wire).

Cone

Do the same as for Sphere.

Convex Hull
This is more complex. you could try to generate your own using python, or you could try one of these existing options:

The Convex Hull operator built into blender. 

Duplicate target object (ShiftD)
With the duplicate selected, enter edit mode (Tab) and select all (A)
Run the convex hull operator (Space> Search > Convex Hull)

This Convex Hull generator written in python.

Existing addons
I also found a couple existing scripts/addons from a quick google search:

One for exporting to YAML
