A NEW AIRCRAFT FUSELAGE CONFIGURATION?

Easy with GEF4!

EclipseCon France 2017 Xavier JACQUES

Ref. presentation : EclipseCon France 2017

AGENDA


1. User interactions

2. Main GEF4 components

3. Geometry 2D/3D calculation

4. Cabin simulator video

2

INTRO


Main Airbus requirements

Easy to use

Allow unconventionnal aircraft configuration

Precise geometry calculation

Graphical Editing Framework (GEF4)

Provide components to create graphical application

Rendered in JAVA FX Scene

Project started mid 2015

GEF4 was only in its first snapshot V0.1.0 (Mars release)

Currently using GEF4 V1.0.0 (Neon release)

MAIN VIEW

Ref. presentation : EclipseCon France 2017 4

DECK VIEWS


Passenger deck

Cargo deck

5


USER INTERACTIONS

ZOOM IN/OUT - PAN


Easy moves

Line thickness adapted to zoom level

Can I navigate

easily on my

layouts?

7

HOVER


Selection hover

Hover menu

How can I

interact with

elements?

8

CLICKABLE AREA


Increase hover trigger area

It’s difficult to

select certain

elements

9

PALETTE


Focusable palette

How can I

interact with

the view?

10

JAVA FX COMPONENT INTEGRATION


Viewer overlay or underlay

Right click palette – JAVA FX Popup

Can I easily

create

elements?

11

JAVA FX COMPONENT INTEGRATION


JAVA FX TableView

Can I have

cabin info on

the view?

12

ELEMENTS CREATION


It should be

very fast to

create seats

13

FRONT VIEW


Height element positioning check

I’d like to see

aircraft section

at location I

want

14

MEASUREMENTS


Measure spacing between every elements

I’d like to

measure

everything in the

cabin

GEOMETRY 2D/3D CALCULATION

GEF4 GEOMETRY


Provided by geometry plug-in

Define 3 main geometry interfaces for visual elements

ICurve

IShape

IMultishape

Provide geometry relationship utilites

Touches

Intersect

Get intersection points

Contains

24

FUSELAGE 3D DEFINITION


Discretized with multiple cross section

A cross section is a fuselage cut at a given position

25

FUSELAGE 3D DEFINITION


User has the possibility to create cross section shape

Then other cross section are automatically computed

26

AIRCRAFT ENVELOPE DEFINITION


360 segments connect each user defined cross sections

Interpolated with splines

27

CROSS SECTION COMPUTATION


Intersections between a plan and all segments

Cross section saved as a Polygon

28

AIRCRAFT GEOMETRY EXAMPLE


With 3 cross sections defined by user

Top View

Side View

29

GEOMETRY ELEMENT COMPUTATION EXAMPLE


Deck floor geometry top view computation

Intersection between Polygon and Line on every cross section

30

GEOMETRY ELEMENT COMPUTATION EXAMPLE


Floor geometry result saved in a Polygon

Floor top view representation

31

COLLISION CHECK ENGINE


Check 2D/3D clash

Help user to validate his aircraft and cabin layouts

Heavy usage of touches() and contains() method

32


CABIN SIMULATOR

Graphical rendering demo

CABIN SIMULATOR


Multi agent simulation

Simulate boarding and deplaning

Multiple parameterizations

‐ Passenger physical characteristics

‐ Passenger behaviors

‐ Doors, seats affectation

Based on passenger deck view

Reuse graphical code

Removal of user interaction

Only addition : Passenger and luggage drawings

34

CABIN SIMULATOR DEMO


CONCLUSION


Hard Start

Long learning curve

Bindings and injections are complicated to understand

Best way to learn: Analyze logo example and other small examples

Good results

Good feedback from users

Nice graphical rendering

Good performance

Special thanks to Alexander Nyssen and Matthias Wienand for their help!
