Hi!

On Intel UHD cards the demo crashes, unless I set the canGenerateDrawCallsViaShader property to false (here). The error message is:

#

I accept if you don't change anything but it might worth a mention in the FAQ section, so others won't debug the same issue for as long as I have.

Thanks

I tried buidling on a linux machine and I end up with errors in SwtHelperWin32 no matter what I do. I've tried specifying the linux maven profiles.

To me it seems like this is caused by 33bd2b1

Hi! I'm new to graphics programming and I am learning OpenGL. Thank you for this repo. I am learning a lot.

For most of the examples I get this error on my MacBook because Apple dropped support for OpenGL 4.3. I'm hoping there is a way around this or do I have to buy a non mac computer?

[LWJGL] GLFW_VERSION_UNAVAILABLE error
Description : Requested OpenGL version 4.3, got version 4.1

I'm slowly going through each example. Tried running examples in raytracing.tutorial package and I get that error.

When I try the demos I get errors like:

They now only show the background color and sometimes even crash when closing the window.
This is likely just because of an API change in BGFX (even though the demos don't seem to be directly affected by it - no compile error).
Tested with JDK 8 b131 on Windows 7 x64.

Example crash log:

Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code)
C  [bgfx.dll+0x6c62]

Everything works fine with 3.1.2-SNAPSHOT.

The vulkan demo collection is pretty thorough with the basic ClearScreenDemo, 3D with depth (TwoRotatingTrianglesInvDepthDemo) and ray tracing.

I'm quite new to vulkan, and would like it if a textured quad demo could be added to the vulkan demos. I might end up writing it myself once I figure out this api in depth.

Hi, thanks for the wonderful introductions to Vulkan in LWJGL.

To prevent the following error when runnning InstancedSpheresDemo.java, I need to put Thread.sleep(40); before vkQueueWaitIdle(queue);:

[mvk-warn] VK_TIMEOUT: vkQueueWaitIdle timed out after 10 frames while awaiting 1 swapchain image presentations to complete.
ERROR OCCURED: VK_TIMEOUT: vkQueueWaitIdle timed out after 10 frames while awaiting 1 swapchain image presentations to complete.
libc++abi: terminating due to uncaught exception of type std::__1::system_error: mutex lock failed: Invalid argument

I don't think it's specific to this demo, this is just an example. I'm only starting to learn the Vulkan API so can't quite work out whether perhaps Host access to queue must be externally synchronised is violated, or there is some other reason for the timeout.

I'm using the JVM flag -XstartOnFirstThread because I'm on macOS; could that be relevant?

Regarding the example at https://github.com/LWJGL/lwjgl3-demos/blob/master/src/org/lwjgl/demo/opengl/swt/SwtDemo.java

The proposed recursive call for
display.asyncExec(new Runnable() {
renderThings();
display.asyncExec( this )
}
means that the async job queue is never empty. When running in Eclipse RCP environment, repositioning parts of RCP application waits until the queue is finished, but since this never happens, an attempt to move parts causes the entire application to stuck forever.

Hi,

Some of your examples, do require a higher OpenGL version. I think it would be handy if you added theese lines of code to support OS X users, and force the OS to run OpenGL 3.0 or higher!

glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3)
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3)
glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE)
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE)

It's really hard to understand this stuff without docs or demo. PointerBuffer causes the process crash and i can't do anything

Hello.

I am encountering an exception access violation when loading image resources with org.lwjgl.stb.STBImage.stbi_load_from_memory. I have copied ioResourceToByteBuffer from lwjgl3-demos/src/org/lwjgl/demo/util/IOUtils.java into my project and am using it as the ByteBuffer input for stbi_load_from_memory. I can supply a crash report upon request.

As far as I can tell, I am using ioResourceToByteBuffer in the same way as demonstrated in the lwjgl3 demos, but I am calling it from multiple threads. There does not seem to be a pattern to when the crash occurs. Are there any synchronization issues or limitations for ioResourceToByteBuffer or stbi_load_from_memory?

I am open to any suggestions on how to debug this issue and willing to supply any information I can gather.

I finished intro1-5 but now don't know which one im supposed to look at next, is there a order im supposed to read through?

I am using the NVIDIA 364.19 driver on an NVIDIA GeForce GT 750M in Ubuntu 16.04 LTS. I was able to build the demo suite just fine:

git clone https://github.com/LWJGL/lwjgl3-demos.git
cd lwjgl3-demos
mvn package

The SpaceGame demo runs without any problems:

java -jar target/lwjgl3-demos.jar

However, when I try to run one of the Vulkan demos:

java -cp target/lwjgl3-demos.jar org.lwjgl.demo.vulkan.ClearScreenDemo

A window titled "GLFW Vulkan Demo" appears for a split second, then the demo crashes with this error:

ERROR OCCURED: vkCreateImage: image creation failed due to invalid parameter
Exception in thread "main" java.lang.AssertionError: Failed to create swap chain: A validation layer found an error.

    at org.lwjgl.demo.vulkan.ClearScreenDemo.main(ClearScreenDemo.java:997)

Is this a bug, or have I just not properly configured my system to use Vulkan?

attempt to remove all external dependencies, some "good" google trash prevent compilation, down-stream

Can we have some tags matching the demos to be compatible with the LWJGL3 release?

Keeping the demos working with the latest and greatest features of LWJGL3 snapshot is great, but sometimes we need to run them against the official (current) release from Maven Central just to see what the demos are all about.

Currently I need to run the demos against the 3.2.3 version from Maven Central, and I'm having big trouble just to compile them. If we have some tag marking them compatible with the 3.2.3 release, it would be a great help.

Unfortunately with both Java 11 and 16 I cannot start the demos.

Without specifying the main class, I get a crash:

I'm not sure what's going wrong here.

Cloned the repo, ran "mvnw package" as indicated in readme, following error produced. Seems to be having issues finding the opengl, par, bgfx and vma natives listed in the pom.xml.

Currently, rotating the camera via the exposed controls results in the camera spinning very fast before slowing down. The issue is visible when pressing either the Q or E button, or by dragging the mouse with the right mouse button pressed.

I'm quite sure that is not intended. However, I could not find the change that "broke" it upon taking a quick glance at the files history.

(A video showcasing the current behavior can be found here: https://youtu.be/fhPqu4c41u0).

When I clone the repo and run mvn clean install the build fails with the following error. Removing the lines referencing the Stdio class allows the build to continue.

eclipse simple java project without any other setup tasks, including maven project setup should not be required.
making the source files compatible with an IDE directly, and not using a script compilation file would be more useful for code exploration. Also any possible dependency to external libraries other than the lwjgl3 library should be removed.

k.i.s.s., just imho. the joml package dependency is not in the repository.

When I try to run some examples (AtomicDemo, for example), I get exceptions like

Message: 0:0(0): error: Compute shaders require GLSL 4.30 or GLSL ES 3.10 

I managed to fix this issues myself with some trivial changes to the code, but I wonder, why am I getting such errors, is it a problem with my setup, or demo code needs some maintenance? I am running ubuntu 22 and use Intel uhd graphics for 10'th gen.

Hi,

I don't know how other people start with lwjgl3 but I certainly start with copy paste from some boilerplate (namely this repository :D)

So far I am assuming something like BSD/Unlicense/Apache but please make it clear by putting a license in the repo.

I can run all Vulkan demos except the NvRayTracing (expected, right?) and ClearScreenDemo. I am on a mobile Intel GPU. I can modify the demo lines 232-233 and get rid of the part requiring VK_PHYSICAL_DEVICE_TYPE_DISCRETE_GPU, and the demo then works fine. The two NvRayTracing demos also have lines requiring VK_PHYSICAL_DEVICE_TYPE_DISCRETE_GPU, and none of the other demos have that.
