Android Question JPCT-AE Load3DS on transparent background

[peacemaker]

Is it possible to show .3DS model transparently ?
Over my panel with picture.

 

[DonManfred]

Is it possible to load .3ds at all? I don´t know a way. Even don´t know this Extension....

 

[peacemaker]

Yes, this JPCT-AE lib has a sample "load3ds" that load .3ds file (of 3D-Max editor software) with .jpg texture file and rotating on the screen. But over the blue color.

 

[wonder]

It should be, as the 3D model is totally independent from its background.
You'll have to fiddle with the code to get it find the right option.

For the background color is used

Dim SkyColor As JpctRGBColor
SkyColor.Initialize3(153, 217, 234, 0)

It can be initialized with only exact R, G, B components.
But how to make it transparent ?

 

[DonManfred]

SkyColor.Initialize3(153, 217, 234, 0)

what is the 4rd parameter?

Note i do not know/have the Lib....

Alfa

 

[DonManfred]

a = Alpha? Set here 128 and check if it is 50% transparent
0 = Fully Opaque
255 = Fully transparent

 

[peacemaker]

Sure, checked - no changes.

I have an old project stored somewhere, I'll have a look at it once I get home (10 hours later).

End result:

Manifest:

SetActivityAttribute(main, android:theme, @android:style/Theme.Translucent.NoTitleBar)

Activity_Create:

'Makes Activity transparent
Activity.Color = Colors.Transparent

jPCT Initialization:

'Makes the view transparent
JpctView.Initialize1("Jpct", 1, True, Jpct.RENDER_CONTINUOUSLY, False, Jpct.TRANSLUCENT)

'Makes the sky transparent
SkyColor.Initialize3(0, 0, 0, 0)

'Solves the problem of black being displayed as transparent (see below)
MyTexture.Initialize2(File.OpenInput(File.DirAssets, "my_texture.png"), True)
