jogl | Java™ Binding for the OpenGL® API

I am currently writting a game with the JOGL bindings to use OpenGL but I am so struggling on this.

I need to initialize my vaos and vbos (for each component) using the GL2 variable that I collected in the init method in the class that implements GLEventListener. Like so,

I am currently learning jogl so I can make my own 2d game. All the textures for the tiles are stored in a single large tileset. I tried to use Texture.getSubImageTexCoords() to draw a single tile, but the result was weird:

I'm not sure exactly how to describe it, but the upper left triangle that makes up the quad is stretching in a very strange way. I want to display just a section of the tileset. I tried looking for something online but couldn't find anything.

here is my code:

I am using Eclipse and Maven to create a Maven package that is uploaded to MyGet to be consumed by other users. I would like to make it so that when my package is referenced as a dependency and therefore downloaded from MyGet, the source attachment is also downloaded.

I've seen this happen with, for example, the JOGL library - when my Maven project in Eclipse references JOGL, I end up with the following files in the ~/.m2/repository subdirectory associated with JOGL (among others):

• jogl-all-main-2.3.2.jar
• jogl-all-main-2.3.2-sources.jar

And in Eclipse, if I right click on the jogl-all-main-2.3.2.jar library and choose Properties, it shows the source attachment as jogl-all-main-2.3.2-sources.jar located in my .m2 folder. I don't believe that I did anything to select that file as the source attachment; I think it happened automatically.

When I upload my package to MyGet, it allows me to upload one or more jar files, but it expects each jar file to be a Maven package including a pom.xml file, so I can't upload the sources jar file to MyGet directly.

Perhaps this is a limitation of MyGet, in that it doesn't allow me to upload the sources in parallel. I'm not familiar enough with Maven to know if it's something that I need to specify in the pom.xml for my package.

While compiling JOGL code, I am getting following error

class file for com.jogamp.common.type.WriteCloneable not found

I also attached a screenshot of the error:

Here is the code:

I am completely stuck here, so any help would be appreciated :/

I'm trying to learn how to use OpenGL 4.0 using it's Java Bindings, JOGL. It seems like now it's better to use VBO/VAOs as opposed to glBegin/End.

I'm following various sources, but for this specific aspect I used this: https://learnopengl.com/Getting-started/Hello-Triangle (C++)

Unfortunately, when I run my program, it throws the following exception (@ Line 41): "Exception in thread "AWT-EventQueue-0" com.jogamp.opengl.GLException: Caught GLException: GL_INVALID_OPERATION: Buffer for target 0x8892 not bound on thread AWT-EventQueue-0"

Here's my full GLEventListener implementing class (Renderer):

I know there is a way to program with Processing P3D in an external IDE.

I have successfully been able to run 2D and P3D sketches within NetBeans IDE. But if I build the project to a JAR file with Processing P3D in my sketch, and try to run the JAR file, I get this error:

I'm trying to run this example (https://github.com/xinwucwp/mhe) on netbeans 8.2 + jython module (ver. 2.7.2). I created a new jython project and added a start.py file with code from demo2.py (from example), here the full file - https://pastebin.com/DqBrDmnN.

As i understand, i have to add path to java classes - *.jar files.

After that, i tried to run it and got the following error - from edu.mines.jtk.ogl.Gl import * java.lang.NoClassDefFoundError: com/jogamp/opengl/GLArrayData, although i've already added jogl-all.jar, which includes GLArrayData.class.

I have OpenJFX 14 app and I need to create OpenGL surface (where I can use a something like glColor() and other functions, i.e. JOGL). I know that OpenJFX supports an importing of 3D models but I have very difficult dynamic 3D scene with shaders and particles (default 3D features aren't enough).

Is it possible to initialise OpenGL context and show viewport inside OpenJFX app using a some wrapper library for OpenGL API like JOGL or another?

I'm using Java2D in conjunction with apache batik to draw some fairly large svg images.

So far it is working quite nicely, but i am frustrated with the performance of areas. In particular, i have three things i want to accomplish:

1. merge a bunch of colliding shapes to one large area
2. removing a bunch of shapes from one large area
3. checking for colliding shapes

naively, point 1 and 2 can be accomplished with Area.add and Area.subtract. This works, but can easily take up to twenty minutes in an average use case.

Point 3 can be accomplished by subtracting the areas from each other and checking the remaing area. Still slow, but can be sped up to be usable by using some prior spatial hashing or something similar.

Is there a better and faster way to merge/subtract Java2D areas? If not, is there another library which can do this sort of thing faster?

unfortunately, libraries like JOGL or LWJGL do not work on a resolution independent space like svg-paths or the Java2D Paths.
