And what is supposed to be in visList.vobj[0]? It's become null as I tinkered with the World class.

It does look horizontally flipped, but obviously there's more to it than that. Try ORing the prixel data with the appropriate value (255?) to make sure it's opaque.

Happy 95% of what remains of this year, pal.

What's with WorldProcessor.createWSNormals()? It seems to me to be both a waste of processing time and a waste of memory.

About that, I made a GenericBuffer<T> class to mimic Java's xBuffer classes. But there's a chunk in convertTexture() where you do IntBuffer (GenericBuffer<int> in mine) buf = getSmallBuffer(); GL11.GenTextures(buf) and then you claim that the texture refence is now in buf. But buf is a local variable that's never called again.

I added the test. And then I think I fixed another issue. Now I'm only getting the appropriate background color, and convertTexture(Texture) is printing [ 12/30/2020 3:57:37 AM ] - ERROR: Failed to upload texture! texID, unhelpfully (helplessly?) is always 0.

Tell me if you think that the numbers matching here is sufficient proof that it's the same thing (the ifs are there just in case):

int ALPHA = 255 << 24;
uint r = 1, g = 1, b = 2;
if ((r & 0xffffff00) != 0) {
r = (255u >> (int)(r >> 28 & 8));
}
if ((g & 0xffffff00) != 0) {
g = (255u >> (int)(g >> 28 & 8));
}
if ((b & 0xffffff00) != 0) {
b = (255u >> (int)(b >> 28 & 8));
}
uint fromSigned = (uint)(b | (g << 8) | (r << 16) | ALPHA);
uint fromUnsigned = b | (g << 8) | (r << 16) |4278190080u;
System.Console.WriteLine("OR from Signed: "+fromSigned +", from Unsigned: "+fromUnsigned);


Does it make any difference to bitwise OR 4278190080u and -16777216 (for alpha values) if the result will nevertheless be an unsigned int (I apologize in advance for the C#)?

Other than new Object3D(object3D, true) with true being reuseMesh, I don't think so.

Apparently this caused the following error:

Quote
Unhandled Exception: System.ArgumentException: An item with the same key has already been added.
   at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)

   at Texture.setMarker(Int32 mark)
   at AWTGLRenderer.drawStrip(VisList visList, Int32 ind, Int32 length, FrameBuffer buffer, World world)

Note that I've changed nothing about the setMarker method (though wouldn't the Hashtable class complain about the same problem?).

I hadn't had  need of compiled objects because I was using the software renderer, so I don't have them yet.

What does it mean that only drawVertexArray() is being called (drawStrip() and drawPolygon() aren't)?

Yes, everything looks exactly the same (that screenshot was from the C-sharp software renderer, so there's no question that the loading  is done right).

Hahah, it's supposed to be Vader (at exactly this lighting and distance):

The problem there was that it's not paintGL in OpenTK, it's OnPaint. I solved that one. I'm happy that it now clears to the right color. drawWireframe() tells me the right color for the wireframe, but draws nothing, and draw() makes a mess. Still, I'm very happy to be achieving any kind of drawing. Any insight here would be greatly appreciated (see below video).

Thank you. I manually called init(...), but now I'm getting a black screen.

The following code
System.Console.WriteLine("execute(int, object[]): Parameters null? "+(parameters==null) +" Init? "+isInit +" Mode: "+mode);

prints the following:

Quote
execute(int, object[]): Parameters null? False Init? True Mode: 2
execute(int, object[]): Parameters null? False Init? True Mode: 0
execute(int, object[]): Parameters null? True Init? True Mode: 8
execute(int, object[]): Parameters null? True Init? True Mode: 1
execute(int, object[]): Parameters null? False Init? True Mode: 2
execute(int, object[]): Parameters null? False Init? True Mode: 0
Expanding command queue to 3000 entries!
execute(int, object[]): Parameters null? True Init? True Mode: 8
execute(int, object[]): Parameters null? True Init? True Mode: 1
execute(int, object[]): Parameters null? False Init? True Mode: 2
execute(int, object[]): Parameters null? False Init? True Mode: 0
and so on.

Do you have any useful insight here?

I moved it to AWTGLRenderer! init((int, int, int, int, int) doesn't call it, init() does and I can't see what calls init().
