Please test VulkanSceneGraph, vsgXchange and vsgExamples master in prep for dev releases!

[robertosfield]

Hi All,

I have completed a big round of bug fixes, optimizations, reviewed and merged submissions and introduced some new capabilities to better support mesh shaders into the VSG, vsgXchange and vsgExamples. Now it's time to wrap this work all up in a nice dev release bow :-)

Before I can do that I'd love some community testing of the respective VSG, vsgXchange and vsgExamples masters to see how well they all work across a range of OS, dev tools and application types.

So please test and let me know of success or failures that you encounter so I know how close we are to converging towards a solid set of dev releases.

Thanks your help.
Robert.

Hi Robert,

I pulled all the latest VSG masters. They all build on Kubuntu and Windows 11. I also tried vsgExamples on Kubuntu and it built without problem. I only ran vsgdraw and vsgviewer.

There are a couple of patches I need to apply to get Spatial Integration to build and work properly. SI uses texture arrays, so the assumption that VkDescriptorSetLayoutBinding.descriptorCount in vsg::Descriptors is always 1 isn't valid. PR #1737 proposes a fix and has more explanation.

I've also been running a patch for handling modifier keys in Linux when used in ImGui. They can have unpredictable consequences if you get the combination wrong, which is easy to do. While tidying vsg-dev/vsgImGui#82 I found out that it can also cause a problem in Windows. More info in the PR.

PR #1738 adds functionality, so is not needed for the developer release. It provides the VSG back end for drag and drop from the operating system (Linux and Windows).

Looking forward to getting back on the master branch.

Regards,
Roland

I mage reviewed and merged Roland's changes, and have update vsgImGui to pull in the latest imgui and implot releases. Changes are: vsg-dev/vsgImGui@7b4c10a

I am ready to tag dev releases, I'll now do another round of testing at my end and if everything goes fine will go ahead with tagging the various VSG projects for their dev releases.

Hi Robert,

I got errors when compiling vsgExamples:

vsgExamples\examples\meshshaders\vsgmeshshaderset\../../../data/shaders/mesh_common.h(35,10): error C3646: vertex_offset: unknown override specifier
vsgExamples\examples\meshshaders\vsgmeshshaderset\../../../data/shaders/mesh_common.h(36,10): error C3646: triangle_offset: unknown override specifier

vsgExamples\examples\meshshaders\vsgmeshshaderset\../../../data/shaders/mesh_common.h(43,10): error C3646: count: unknown override specifier

Replacing uint with uint32_t in mesh_common.h helped me.

Win10, VS2022

To address this I have added a C++ specific define of uint to the mesh_common.h, I'm working on Linux right now so will need to boot up my Windows 11 system to double check it works. Change is checked into vsgExamples master:

Yes, it works for me.
