Purpose of a Stomach Access Panel

Post by mister_minations » Fri Oct 07, 2022 8:56 pm

The easiest possible answer: aesthetics
Midriffs are frequently exposed, and the large surface area is a good place to apply manipulations.

Similarly, access panels are usually put on body areas with few moving parts. For example, chest panels (ie above cleavage) are a good place to put status lights, buttons, and display screens. Panels can be put on the back with similar decorations.

For this reason, access panels function as an additional layer over the original subject model. The layer contents in question, in accordance with individual frames, will rotate and move positions slightly over the course of a given motion. Complexities will arise if the model moves in a manner that shifts perspective of the panel, requiring redrafting key elements in the base and custom layers (specifically, panels are depressions, so the edges of skin will appear to bulge outward).

A difficult answer: functionality
The abdomen moves along with the spine. Functionally, it would make little sense to put an a display screen in the middle of a gynoid's stomach; the screen would have to bend and twist. Even small buttons are difficult to justify because there's a chance that certain maneuvers would accidentally trigger some control if preventative measures aren't implement.

What does this mean?
An abdomen panel would most likely contain wires, tubing, pistons, and some spine analogue.
Each element represents a different layer, with each layer moving in accordance with the original model but separately of one another to simulate the effects of an interlinked mechanical assembly.

The torso would house critical computation cores and the hips would contain motor assemblies. Motion would be represented by a number of pistons pumping up and down in response to large movements. Since a torso would likely also contain fluid reservoirs, tubing in the abdomen would move fluids to the hip motor assembly, causing vibrations when a sufficiently high volume of liquids move through the assembly.

The difficulty of replicating the above motion depends on whether or not the subject is bending over. A standing subject would require minimal redrawing of individual frames, accounting only for minimal adjustments of rotation and position. However, if the abdomen bends, tubing and pistons must bend correspondingly, requiring the redrawing of each individual component.
(the issue is further compounded by shadow effects, as the direction of the light source may not necessarily remain constant)

Manipulation did not come out as intended (panel outline at frame 9 does not align with rest of body)

Will attempt to redo at some point
Current version kept for reference

EDIT: 10-9-222, 10:34PM
Updated so that frames after 9 don't "slide" upwards (still vibrates a little)
Reduced size and details to allow for thumbnail animation

Cool using Tocarra as your model to show the access panel! :)

Breakdown of the Stomach Panel Used for Above Image
(note: terminology may be incorrect)

Image

1. Outline
Metal ring used to provide transition between skin and mechanical components
  • Intended Effects: None
  • Actual Effects: None
2. Sheet
Metal components at the bottom of the torso assembly and top of the hip assembly, respectively
  • Intended Effects: None
  • Actual Effects: None
3. Wires * 2
Electrical wires, provide data transfer from torso processing unit and hip assembly
  • Intended Effects: Vibrate with given movement
  • Actual Effects: None
4. Control Panel
Data ports and indicator lights for hip assembly
  • Intended Effects: Blinking lights
  • Actual Effects: Hidden behind tubing, effect not visible
5. Piston Assembly * 3
Three separate layers, consists of a spring on an arm that moves along a metal pole
  • Intended Effects: Spring and arm bounces alongside model's movements
  • Actual Effects: Did not set up a proper idle animation, subsequent motions occur too fast
6. Tubing
Takes fluids from torso assembly and moves them to hip assembly
  • Intended Effects: Moving fluids
  • Actual Effects: Too opaque, effect not visible
7. Spine
Main support structure for endoskeleton
  • Intended Effects: Indicator lights blink, tracing shape of spine
  • Actual Effects: Hidden behind tubing, effect not visible
8. Interior Cavity
Completely concealed by previous elements
  • Intended Effects: None
  • Actual Effects: None
Lessons Learned
  • Need better way to set outlines to avoid inaccurate panel movements
  • Chaining movements, items in stomach panels should move alongside main body
  • Indicator lights need to be more visible against shadows
  • Tubing needs to either be lighter in color or more transparent
  • Even the slightest twist or stretch requires alterations to the torso assembly

When making the animation, I originally wanted the phone connected to a controller in the abdominal cavity via a cable. Whenever the model typed a command on her phone, lights on the controller would flash, and fluids would flow down the tubing. However, due to the low quality of the original image, it was difficult at times to tell the precise location of the phone, which made drawing the cable difficult. In addition, fluid dynamics are at play, so drawing fluids moving across tubing isn't a trivial task.

Alternatively, a cable could've hung from the open access panel. The cable wouldn't have served a practical purpose. However, it would dangle for a bit as the model typed, moving in synchronization with her movements.

In this particular instance, other elements were placed to avoid obscuring the spine (the tubing, of course, is transparent). As a result, it's more visible, allowing for visibility of blinking indicator lights along the assembly. However, the position of the model's hands were not taken into account, obscuring the spring in the piston assembly.
