Planetary Orbits, using Matrix Library

[Bert Mariani]

Hello Mahmoud et ALL

Planetary-Orbits-1.ring

This is another contribution to the Orbital Mechanics section

It uses the Matrix Library for the Transforms of the view display

Attached is: 

     Planetary-Orbits-ZIP.zip

          - Planetary-Orbits-1.rin

          - Planet images are in the zip file

                 - Icarus-Asteroid , and Halley-Comet, Ceres-Asteroid-Belt

Basic instructions:

 - Select a Planet to display in the drop-down menu at the top-left

 - Click on Start/Calc to calculate the orbit points into a matrix array

 - Click on DrawMatrix to draw the planetary orbit.

 - There are 2 check-boxes

        - OneDraw:  on => one orbit only,   off => multiple orbits,  

                                        Fixed Size to show Eccentricity

         - MultiOrbits: on => log scaled display of multiple planets

 - View

        - Top down view of orbits when "RotationAngle" X = 0 degrees

        -  Tilted view of orbits when "RotationAngle" X = 60 degrees

        -  X, Y, Z angle can be used to vary the display

======================================

Screen Captures 

Note the Eccentricity of Mercury compared to Earth

Icarus is an Asteroid that gets closer to the Sun than Mercury and beyond Mars

Foci (Focus) of the Elliptical orbit are drawn in Red

Top-Down view from North of the entire Solar System

View is tilted 60 degrees in X-Axis for another perspective

Pluto get closed than Neptune for part of its eccentric orbit

Halley's Comet travels Way beyond Pluto.

Halley's orbital period has varied between 74 and 79 years since 240 BC

Last seen in 1986

Hello Bert

Very nice work, Thanks for sharing :D

Suggestion: Adding a button called (Play) or (Animation)

Once we click on this button

The application adds the planets one by one (Setting values, Calc., & Drawing)

So, we can see the great results (screen shots) that you shared automatically without setting parameters.

Greetings,

Mahmoud

Hello Mahmoud et ALL

Updated version 2      Planetary-Orbits-2.ring

Attached is:                 Planetary-Orbits-ZIP.zip

It can draw Single Planet and Overlay other planets to compare orbit eccentricity

    - Select Planet,  Start/Calc, DrawOrbit

    - OneDraw checkbox controls how may planets are overladed

It can draw the Inner Planets, Outer Planets or ALL Planets using the checkboxes

    -  DrawALLOrbits will draw multiple orbits    ( OneDraw = off )

It now includes Animation.

    - Animation  button will start the planet/s  moving through their orbits at proper relative speed.

It can Tilt the View Angle for 3D using the X-Axes  or Rotate the display using the Z-axis around the center point

=============================

Inner Planets + Animation

InnerPlanets = on,  OuterPlanets = off,  DrawALLOrbits,  Animation

Outer Planets + Animation

InnerPlanets = off   OuterPlanets = on,  DrawALLOrbits,  Animation

View angle  X=60  Z=10

ALL Planets + Animation

InnerPlanets = on,  OuterPlanets = on,  DrawALLOrbits,  Animation

Single Planet - Overlay  ---  OneDraw = off

Select Planet, StartCalc, DrawOrbit

X Axis = 0,  Z-Axis = 0  for top-down view of orbit eccentricity

Hello Bert

The simulation looks beautiful :D

Thank you very much for the update.

Hello Mahmoud et ALL

Sorry ... forgot to attach. Mea culpa !

Here it is.

Hello Bert

The file: SolarSystem3.jpg is missing

Hello Mahmoud,

you need to extract new archive over old one. New archive doesn't contain images.

New version is much faster, making orbit calculation instantly. Excellent work Bert.

Hello Mahmoud, Illir et ALL

"You need to extract new archive over old one"

All the images were updated to "png" which can be made transparent using Paint 3D
