Drawing more than a certain number of triangles at one time/method/stack crash

I have a GLJPanel with swing components (JInternalPane renders beautifully on top). On render, the parent container/gl event listener (JDesktopPane) calls the game's render, which calls the level's render. Inside the level's render, I have about 24,000 float vertices waiting to be drawn. Cutting the for loop short by a few thousand vertices seems to not crash, but rendering all of them does. Other than that, everything seems to work.

SO.. when I go over, I get spammed with this crap (again, Swing DispatchThread woes -.-):

Here's the code:

This doesn't work:

                gl2.glBegin(GL2.GL_TRIANGLES);
                for (int i = 0; i < terrainTris.length-6; i+=6) {

                        gl2.glVertex3f(terrainTris[i].x, terrainTris[i].y, terrainTris[i].z);
                        gl2.glVertex3f(terrainTris[i+1].x, terrainTris[i+1].y, terrainTris[i+1].z);
                        gl2.glVertex3f(terrainTris[i+2].x, terrainTris[i+2].y, terrainTris[i+2].z);

                        gl2.glVertex3f(terrainTris[i+5].x, terrainTris[i+5].y, terrainTris[i+5].z);

                       
                }
                gl2.glEnd();

This doesn't work:
                for (int i = 0; i < terrainTris.length-200; i+=6) {

This, however, DOES work:
                for (int i = 0; i < terrainTris.length-2000; i+=6) {


What gives? I tried calling the GLJPanel's paint, repaint and display; in many ways: separate thread, separate thread with sleep, same thread with FPSAnimator, different thread with FPSAnimator, etc, etc.
Am I running out of memory? If so, how can I avoid this? Would VBOs help in any way?

Unless explicitely needed, you should avoid deprecated OpenGL, loremipsum

It might not be releated to the EDT at all
but to available GPU memory?
We would expect a failure while creating the vertices buffers,
but since you utilize the fixed function pipeline (FFP)
these might get aggregated 'on the fly'.

Try using VBOs and glDraw* commands (as elect recommended)
as see how the memory allocation goes ..

Hi

You can use com.jogamp.opengl.util.ImmModeSink in order to minimize the changes in your code and still benefit of retained mode instead of using immediate mode. By the way, immediate mode shouldn't be used even for compatibility reasons (it's badly supported in numerous drivers like the display lists, you might get a large performance penalty when using them with shaders or during the picking). The vertex buffer objects are in the core of OpenGL since its version 1.4 and the vertex arrays are in its core with its version 1.2.

I draw about ten times more triangles in my game and it works flawlessly even in immediate mode. Please give us a SSCCE if you want to get some help.

Well, I got it to work by switching to GL_QUADS. Maybe I had an array improperly initialized... don't know.

However, now I have a next issue:
I can only load textures with AWTTextureIO using a buffered image. TextureIO using a file crashes. Maybe it's meant to be that way. Who knows. GLJPanel issues.

BUT, when I draw, for example, green to the texure, the resulting color is always white. I tried making only a quarter of the texture green, and the rest black. I get a quarter white and the rest black. COLORS AREN'T WORKING!!

I already have GL_TEXTURE_2D enabled, obviously. And color material. The texCoord2f's are correct, cause the image is actually drawing as expected. Just no color...

Oh yeah, and I did try to explicitly set the image data type as well. If I'm not mistaken, BufferedImage.TYPE_INT_RGB should go hand and hand with GL2.GL_RGB. Regardless, the result doesn't budge.

More FTRs:

Tried setting GLCapabilities, lighting is always disabled. Grading either color channel has no effect on the seemingly impervious white. It's either black (if the color is exactly 0,0,0) or white (if the color is anything other than black).

Actually, AWTTextureIO also gives me a crash. The key is when I load from a file (or if I provide the FileInputStream myself).
The crash is a juicy one, too:

Please give us a SSCCE if you want to get some help. You seem to call com.jogamp.opengl.util.texture.TextureIO.newTexture() with no current OpenGL context or from the wrong thread. You can create the texture data anywhere but the texture creation requires a current OpenGL context.

Instead of blaming JOGL, show us your own code which is probably responsible for your problems.

Finally, I switched from quads to triangles several years ago without any trouble.

Thank you, that solved it. The GL context existed and I even ensured that it was the same one being used by passing GL gl into the texture manager. It was due to calling from a different thread. Without BufferedImage, using the loader from file, the texture renders fine with all colors 0.0

You're welcome.

You shouldn't pass GL instances, this is a bad practice, it might lead you to use an invalidated instance. I advise you to look at the renderers of the most famous 3D engines (JMonkeyEngine, LibGDX, JogAmp's Ardor3D Continuation, ...), I call GLContext.getCurrentGL() instead of passing GL instances. If you called getCurrentGL() on the wrong thread or at the wrong time, it would throw an exception with an understandable error message instead of causing a crash.

Well, I advise to pass the GL instance, but treat it only transient,
i.e. do not store/cache it (no persistance) - or you really have to
know what you are doing (lifecycle, threading, ..).

From my viewpoint, it is best practice to pass the GL instance
as it is done in most of our framework - and keep it transient.

getCurrentGL() works ofc, assuming operating from the right thread,
which you control.

It uses TLS storage and hence has a [very] little performance footprint.
Dunno which footprint is bigger, i.e. passing the GL instance or
accessing the TLS for the current GL instance.

In the end .. well, it might be just very academic discussion :)
