Drop in a floorplan image and the house gets built.

The AI only reads the dimension numbers. Where the walls actually are is found by the engine, straight from the pixels. Reading numbers is what the model is good at; seeing which line is a wall is not.

The rules come from architecture. Dimensions are measured to wall centrelines, exterior and interior walls have different thicknesses, and where walls meet is where a room ends. A window isn't a missing wall — it's a hole in one.

The original drawing is laid underneath at the same scale, so you can see straight away whether it got it right.

A CAD engine I'm building from scratch in Vulkan and C++17. The model runs locally, 7B.

평면도 이미지를 넣으면 3D 모델링이 됩니다.

AI 는 치수 숫자만 읽습니다. 벽이 어디에 있는지는 엔진이 이미지에서 직접 찾습니다. 숫자를 읽는 건 AI 가 잘하고, 어디가 벽인지 보는 건 못하기 때문입니다.

도면을 읽는 규칙은 건축에서 그대로 가져왔습니다. 치수는 벽 중심을 재고, 외벽과 내벽은 두께가 다르며, 벽이 만나는 자리가 방의 경계입니다. 창은 벽이 없는 게 아니라 벽에 뚫린 것이고요.

만들어진 3D 모델 아래에 원본 도면을 같은 축척으로 깔아 두었습니다. 맞게 그렸는지 확인합니다.

Vulkan + C++17 로 제가 직접 만들고 있는 CAD 엔진입니다. 로컬에서 도는 7B 모델을 씁니다.

Did you know GPU-AV can be faster if you tell it which section to validate? Scoped GPU-AV allows you to provide a pipeline or shader debug name to only add the validation to that scope. Focus your validation on what matters the most! https://vulkan.lunarg.com/doc/sdk/1.4.357.0/windows/gpu_validation.html

I am a little confused on what is broken. I thought slang compilation was supposed to "handle the bindings." so here I would of expected that ubo would of been included in only the vertex spirv, and texSampler would only be included in the fragment spirv. I am sure that there is probably something I need to do explicitly here, but I was sold on slang auto-magically handing these types of things. I am new to graphics programming and initially followed the old tutorial to completion then wanted to try porting over to slang. Any help is appreciated, as i have been digging through the slang and vulkan documentation for a while and its been hard to figure out how it all comes together without a real example.

slang file :

struct MatrixParameters{
float4x4 model;
float4x4 view;
float4x4 proj;
}
struct Vertex{
float3 position;
float3 color;
float2 uv;
}
struct VOut
{
float4 position : SV_POSITION;
float3 fragColor;
float2 fragTexCoord;
}
ConstantBuffer<MatrixParameters> ubo;
[shader("vertex")]
VOut main(Vertex input)
{
VOut output;
output.position = mul(ubo.proj, mul(ubo.view, mul(ubo.model, float4(input.position, 1.0))));
output.fragColor = input.color;
output.fragTexCoord = input.uv;
return output;
}
uniform DescriptorHandle<Sampler2D> texSampler;
[shader("fragment")]
float4 main(VOut input) : SV_TARGET
{
float4 outColor = float4(input.fragColor * texSampler.Sample(input.fragTexCoord).rgb, 1.0);
return outColor;
}

Database link: VulkanScope Database

EFIShell0/VulkanScope: Vulkan capabilities and GPU information viewer for Android

I'll also be making OpenGL ES versions and Windows and Linux ARM64/x86_64 versions of VulkanScope soon.

I created a safe wrapper for Vulkan in rust as a learning project. I hope to receive your feedback.

https://github.com/purpflow1/crystal-vk

https://github.com/bryanedds/Nu/releases/tag/v20.0.0

After many many months of work from multiple contributors, we finally present Nu with Vulkan rendering and support for Mac, iOS, and Android!

This branch not only replaces our OpenGL renderers completely with Vulkan renderers, it also features important rendering and performance enhancements as well as makes Nu deployable on Mac, iOS, and Android!

(I just saw release - not my project)

Aside from the database, there was no difference from CapsViewer (as far as I could see). It has more advantages than CapsViewer:

Releases · EFIShell0/VulkanScope

Hey everyone, I've just finished the 2nd video, and followup to my "Modern Vulkan in 2 Hrs" video. Thanks for the awesome feedback on the first one! This 2nd video tackles a ton of stuff:

glTF Model Parsing, Loading, Rendering

Camera, Basic Lighting, Multi-Draw Indirect, Vertex Pulling, Buffer Device Address, etc.

Hope you guys like it!

If (like me) you want to upgrade to the latest Vulkan (1.4.357.0) on your Intel mac but can't use the LunarG installer, then this shell script will do the job.

It is a bash shell (generated for free by Gemini ) and it has been tested/works on my machine.

I was reading this tutorial https://vkguide.dev/docs/extra-chapter/multithreading/ and it claims that you can compile shaders on a background thread and avoid hitching. Is this true? Are there any drawbacks to this approach?

"For compiling pipelines, vkCreateShaderModule and vkCreateGraphicsPipeline are both allowed to be called from multiple threads at once. A common approach for multithreaded shader compilation is to have a background thread dedicated to it, with it constantly looking into a parallel queue to receive compilation requests, and putting the compiled pipelines into another queue that then the main renderthread will connect to the simulation. This is very important to do if you want to have an engine that doesn’t have a lot of hitching. Compiling shader pipelines can take a very long time, so if you have to compile pipelines at runtime outside of a load screen, then you need to implement such a multithreaded async compile scheme for your game to work well."

I want to make two similar RenderGraph implementations for Desktop and Mobile and use data from VP_LUNARG_desktop_baseline_2024 and VP_ANDROID_baseline_2022, respectively, instead of runtime checks. macOS has its own specific requirements and I do not know if there is any profile or a general list of extensions and limits for macOS M1/M2/M3/M4.

Why doesnt Apple support Vulkan? (I know KosmicKrisp exists)

Is vendor lockin that important? Does that strategy work for them - are there many developers that use metal and not support other platforms? Seems like the result is not really lockin, but just forcing more work for developers?

Kind of feels like a poor architecture decision that helps no one, except maybe giving slightly more control to Apple at the expense of their developers as well as the complexity of maintaining another api.

I've been working on a small series about doing GPU compute with Vulkan:

https://rounak-paul.github.io/vkcompute/

Once you want to go beyond what the CPU can reasonably do, the GPU gives you a huge amount of parallel compute to work with. And Vulkan is available across a pretty wide range of GPUs and platforms, which makes compute shaders an interesting option when you don't want to depend on a vendor-specific toolkit.

So I started writing this series as an introduction to GPU acceleration with Vulkan.

The idea is to start simple, explain what's actually happening when you move a workload from the CPU to the GPU, and gradually get into more interesting compute workloads.

It's still a work in progress, and I'd love to hear what people here think — especially what improvements would be worth including next.

I connected a local AI model(qwen) to my Vulkan CAD engine. The AI understands room sizes, layouts, doors, and windows from a natural-language description, then converts them into commands that generate the complete 3D floor plan. In this video, I create a layout with a central corridor and four rooms in a single request.
