Android Example JPCT-AE Polyline Example

Polyline in JPCT-AE is unable for using by standart methods. But, by Ricardossy1, in his post: Ricardossy1 post, was described way for solving problem.
I was needed for Polylines in my project and jpst-ae wrapper and xml-file was edited in Eclipse from alhowiriny's sources.
Was added some next methods to Polyline Class of wrapper:

1. Essai - creating array of JSimpleVector
2. setTransparencyMode - by default=0 (invisible)
3. setWidth - change Width of line
4. setColor - change Color of Polyline
5. setParent - for linking Polyline to some Object3D in World

example of code:
Sub Clobals

Dim Pl_Line As JpctPolyline
Dim Pl_obj() As Object
Dim Pl_point(3) As JpctSimpleVector

Sub JPCT_SurfaceChanged

Dim i As Int
Dim LineColor As JpctRGBColor
    LineColor.Initialize2(50,100,250)

Pl_obj=Pl_Line.essai(Pl_point.Length) 'Create Array of JSimpleVector

'Filling array of Vectors (Points)
   Pl_point(0).Initialize2(0,125,0)
Pl_obj(0)=Pl_point(0)

   Pl_point(1).Initialize2(0,0,0)
Pl_obj(1)=Pl_point(1)

   Pl_point(2).Initialize2(125,0,0)
Pl_obj(2)=Pl_point(2)

Pl_Line.Initialize(Pl_obj,LineColor) 'Initializing Polyline
Pl_Line.setColor(LineColor)          'SetColor for Polylines
Pl_Line.setPercentage(1)             'Show 100% of Polylines Long
Pl_Line.setVisible(True)             'Set Polyline visible'
Pl_Line.setWidth(3)                  'Set Width of polyline=3


Pl_Line.setTransparencyMode(-1)      'Not Transparent Polyline
World.addPolyline(Pl_Line)           'Add Polyline to World
Pl_Line.setParent(curBody)           'Link Polyline to some Object3D

'Logs for controlling Points-Data in Polyline
Log(Pl_Line.Length)
For i=0 To 2
Log(i)
Log("x=" & Pl_point(i).x)
Log("y=" & Pl_point(i).y)
Log("z=" & Pl_point(i).z)
Log("obj(" & i & ")=" & Pl_obj(i))
Next 'i

Polyline will be enable only with last version of JPCT-AE library! (23/03/2021)

I would like to start studying the possibilities of jPCT with B4X environments
Could you describe the essential steps to activate a simple program that uses the jPCT library in B4X environments?

Hi, amorosik! For a first time i looked for jpct-ae examples at this forum. And also i'm learning java-docs for jpct-ae here: https://www.jpct.net/jpct-ae/
I'm not big specialist for jpct-ae, and this engine was used by me only for creating 3D-atlas of acupuncture in my application... If i can help - i will try help...
