B4J Library jPCT3d (partial wrap)

A bit old ,non complete ,not tested and unsupported (sorry for that ) wrap for jPCT3d library

Reference is very long it needs many posts :D you can generate it yourself from here http://b4a.martinpearman.co.uk/xml2bb/

A small sample (library is very huge ) worked for me on Windows 7 64bit
B4X:
Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
    Dim jpct As SMMjPCT3d
    Private world As World
   
    Private boxtex As Texture
'    Private obj As Object3D
    Private buffer As FrameBuffer
    Dim irender As IRenderer
    Private imagebuffer As ImageView
    Private Primitives As Primitives
    Dim yRot As Float = 0
    Dim loader As Loader
    Dim body , rightFront,leftFront,rightRear,leftRear As Object3D
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    'MainForm.RootPane.LoadLayout("Layout1") 'Load the layout file.
    imagebuffer.Initialize("imagebuffer")
   
    MainForm.Show
    MainForm.RootPane.AddNode(imagebuffer,0,0,MainForm.Width,MainForm.Height)
'   

    jpct.Initialize("jpct",File.DirApp&"\lwjgl64.dll")
    world.Initialize("world")
    irender.Initialize("",MainForm.Width,MainForm.Height,32,32,60)
   

   
   
    If Not(File.Exists(File.DirApp,"box.jpg")) Then
        File.Copy(File.DirAssets,"box.jpg",File.DirApp,"box.jpg")
    End If
   
    If Not(File.Exists(File.DirApp,"rocks.jpg")) Then
        File.Copy(File.DirAssets,"rocks.jpg",File.DirApp,"rocks.jpg")
    End If

Loader for 3DS models Body.mergeAll(Loader.load3DS("model.3ds", 2.0)) takes error for Merging:
java.lang.ArrayStoreException: arraycopy: type mismatch: can not copy smm.jpct.Object3DWrapper[] into com.threed.jpct.Object3D[]

Hi, I am very interested in trying the indicated code to test the functionality of the jPCT library
Despite having tried, I still haven't been able to figure out how to make a working basic example using the code you posted
Could you indicate a sequence of steps to complete to make the code work on the first post?
