blade's Introduction

Blade

Blade is an innovative rendering solution for Rust. It starts with a lean low-level GPU abstraction focused at ergonomics and fun. It then grows into a high-level rendering library that utilizes hardware ray-tracing. It's accompanied by a task-parallel asset pipeline together with egui support, turning into a minimal rendering engine. Finally, the top-level Blade engine combines all of this with Rapier3D-based physics and hides them behind a concise API.

Examples

Instructions

Just the usual 🦀 workflow. E.g. to run the bunny-mark benchmark run:

cargo run --release --example bunnymark

Platforms

The full-stack Blade Engine can only run on Vulkan with hardware Ray Tracing support. However, on secondary platforms, such as Metal and GLES/WebGL2, one can still use Blde-Graphics and Blade-Egui.

blade's Issues

Sporadic GPU crashes on load

Seeing them occasionally as VK_ERROR_DEVICE_LOST coming out of vkQueueSubmit.
Symptoms:

only happens on Sponza, which is a giant scene.
once it starts happening, it keeps happening. Once it works, it keeps working.
seems to be more likely when on battery?
seems to be more likely in debug mode?
often falls on the first or second frame rendered with UI.
when I needed to present this on Rust Gamedev meetup, I disabled most of the UI rendering, and it seemed to improve things.
Markers from #38 always point to BLAS construction. There is only one BLAS, and it's giant.
All primitive/instance/geometry counts are well within limits. All device address alignments are good, too.

panic when resizing window: `Result::unwrap()` on an `Err` value: ERROR_OUT_OF_DATE_KHR

I experienced this on Linux + KDE + X11 + nvidia-drivers.

Steps to reproduce:

checkout blade latest main (commit cda6127 )
cargo run --example particle
resize the window (sometimes one or two times)

Result:

thread 'main' panicked at blade-graphics/src/vulkan/init.rs:812:18:
called `Result::unwrap()` on an `Err` value: ERROR_OUT_OF_DATE_KHR

I originally observed this on the Zed editor (reported downstream at zed-industries/zed#9628 ), but was able to reproduce it with just the particle example.

Some software versions in case that ends up being relevant:

Hard to do anything useful on WebGL backend

Without both the vertex buffer (that aren't yet supported/exposed in Blade) or storage buffers (that aren't supported by WebGL2), the only way to get data into a vertex shader is via uniform buffers or textures. If a mesh is non-trivial, putting it into a texture isn't desirable by any means :)

Support multiple windows

In Zed, we are initializing a graphics context for every window. However, if there is more than one window, we are wasting time re-initializing the connection to the graphics driver, recompiling all the pipelines, etc. If we support multiple windows natively, we could save that time.

Temporary buffers

There is often a need to create a buffer knowing that it's going to perish on the next submit. Exposing a nice API for this is, however, not trivial. I could see at least 3 different approaches:

Just add temporary: bool flag to struct BufferDesc and allocate accordingly. This helps with performance of small allocations, but it doesn't have with ergonomics: the user still has to know when to delete the buffers.
Add something like CommandEncoder::create_temporary_buffer, which would automatically manage its lifetime and destroy whenever the underlying command pool is reset. As nice as this sounds from the ergonomics point of view, it has implementation caveats:
- the logic of tracking temporary buffers is backend-agnostic. We could try moving it into a shared implementation, it's not a lot of code.
- when inside a transfer pass (or any other), we can't borrow CommandEncoder even immutably... We could re-expose this method on the encoders.
- in Vulkan backend, the command encoder doesn't have access to memory. Could be exposed?
Expose a buffer belt primitive in a satellite library. Good thing is that it's fairly versatile. Bad thing is that the API is still not as nice.

Separate README for every crate

So that it looks reasonable on crates io...

In addition, I think we'll have separate CHANGELOG for every crate

VRAM statistics

It would be interesting to get statistics on how much video memory is used by ReSTIR

Annoying way to enable Tracy profiling

Everything is great, except for the fact there needs to be this small line:

let _ = profiling::tracy_client::Client::start();

This line can only be done if profiling/profile-with-tracy is enabled, but cargo/rust don't have a mechanism to check for this.
The standard way to solve it is to add a feature to blade itself, such as profile-tracy. I would like to avoid this as possible - the less features we have the easier it is to configure and test.

is_vulkan_portability is only dependent on the instance extension (which may be available)

Should `descriptor_pool_info` include `FREE_DESCRIPTOR_SET` flag?

From zed-industries/zed#10018 (comment)

Figure out the unique ID mechanics for assets

Turns out the TypeID can't be used, because Rust is happily keeping it the same if the structure changes. Still unique within the program, but not what we expect it to be.

Dynamic backends (or multiple static backends)

Do you have any idea how to make the backends (specifically, GLES or Vulkan) selectable at runtime? For exmaple, by making some object-safe traits? Alternatively, it would help if multiple backends can be activated at the same time (for example, with cargo features, preferably exposed as (non-object-safe) traits too). Then, abstracting over multiple backends could be done by the application.

[meta] Portable Ray Tracing

Stage I: #7

Vulkan wrapper around acceleration structures
Fix naga SPIRV-1.4 target - gfx-rs/naga#2230
Add naga support for ray queries - gfx-rs/naga#2256
Example

Stage II:

metal-rs expose Metal-2 APIs to RT - gfx-rs/metal-rs#256
naga MSL support for ray queries
Metal support for acceleration structures and RT pipelines
Make RT examples portable

Stage III:

Support for RT pipelines in Vulkan and Metal-3
Add naga support for RT shader stages
Example

Switch resource tracking OFF in Metal

This is fairly straightforward - just use new_command_buffer_with_unretained_references instead of new_command_buffer. The user is already responsible for tracking the lifetimes. Should be an easy win, just unclear how big of a win. So we'll need to measure it nicely.

Generate the proper tangent space

Need quality of http://www.mikktspace.com/, but desirable without hooking up to it directly.

Blade on iPadOS / VisionOS?

Blade clearly already supports MacOS via Metal, is it currently supported on iOS specifically iPad?

Zed GLES backend panic: create_platform_window_surface during resize

The GLES backend for Zed is crashing for me under both X11 and Wayland. This has been occuring since at least zed-industries/zed#13114 but has probably been present for much longer. This occurs whenever you resize the window (if doing the hello_world example, which has been there the whole time) or at startup if running Zed (though I don't think this has always been the case).

This is what gets printed out:

My DE is gnome.

crashes on startup for PRIME enabled hardware thats configured to use the onboard nvidia not the intel

... seems to specifically choose the incorrect (intel) video card even tho 'prime-select query' output says 'nvidia'

temporary workaround, switch-around your prime configuration to use the worse 'intel" video card, reboot, and then it won't crash.
run: sudo prime-select intel
reboot

Don't block use of Intel on Nvidia hybrid systems.

The recent commit 30c4fa4 makes it so that things like zed run on the dgpu full time, this is not an acceptable solution for #88 as it causes excessive battery drain, heat, etc.

In that issue I reference gfx-rs/wgpu#4110 because it appears to be a very similar use case.

My own system is currently:

Operating System: Fedora Linux 40
Kernel Version: 6.8.0-rc7+ (64-bit)
Graphics Platform: Wayland
Processors: 32 × Intel® Core™ i9-14900HX
Memory: 62.4 GiB of RAM
Graphics Processor: Mesa Intel® Graphics
Manufacturer: ASUSTeK COMPUTER INC.
Product Name: ROG Strix SCAR 16 G634JYR_G634JYR_000045397
System Version: 1.0

Installed mesa version is: 24.0.0

Installed nvidia version: 550.54.14

I also have older laptops I can test. Plus I have tested on fedora 39 quite fine which used 6.6.x and 6.7.x kernels. The desktop is irrelevant here, I've tested on COSMIC, Gnome, KDE. What is of note however is that I do not use Xorg sessions and haven't done for years.

The proper and expected solution is to find the exact cause of #88 and either fix that, or work around that one specific case. A blanket blocking of all intel/nvidia just handicaps everyone regardless.

Resize warnings on Linux/X11

It looks like the surface doesn't get its size updated, as far as Vulkan is concerned:

VUID-VkSwapchainCreateInfoKHR-pNext-07781(ERROR / SPEC): msgNum: 1284057537 - Validation Error: [ VUID-VkSwapchainCreateInfoKHR-pNext-07781 ] | MessageID = 0x4c8929c1 | vkCreateSwapchainKHR(): pCreateInfo->imageExtent (1025, 659), which is outside the bounds returned by vkGetPhysicalDeviceSurfaceCapabilitiesKHR(): currentExtent = (800,600), minImageExtent = (800,600), maxImageExtent = (800,600). The Vulkan spec states: If a VkSwapchainPresentScalingCreateInfoEXT structure was not included in the pNext chain, or it is included and VkSwapchainPresentScalingCreateInfoEXT::scalingBehavior is zero then imageExtent must be between minImageExtent and maxImageExtent, inclusive, where minImageExtent and maxImageExtent are members of the VkSurfaceCapabilitiesKHR structure returned by vkGetPhysicalDeviceSurfaceCapabilitiesKHR for the surface (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-VkSwapchainCreateInfoKHR-pNext-07781)

Hard to say what the cause is, but it started happening in the last day where I think there was a blade update.

I'd never heard of blade until zed merged it in. Unsure what environment you use, but for me nothing works:

Fails also with attempt to offload to Nvidia dgpu.

wgpu works fine.

"Memory block wasn't deallocated" is printed when exiting Zed builds on Linux

A little sleuthing reveals that this error comes from the gpu_alloc crate, and is run when it's MemoryBlock type is dropped without calling MemoryBlock::deallocate. Probably because the MemoryManager in blade-graphics/src/vulkan/mod.rs isn't being cleared in this case.

egui image loader fails to recognize png with blade-egui

Using blade and attempting to draw an image similar to in eframe results with:
egui_extras::install_image_loaders(ctx); ui.add(Image::new(include_image!("assets/logo.png"));
Using image/egui_extras results in the image loader not registering (works with eframe)

ERROR_INITIALIZATION_FAILED on Linux

Hello, I am getting the error in the title when attempting to run Blade. Got this when testing zed, but tried to run blade-graphics examples directly and they receive the same error. I am able to successfully run vkcube, wgpu apps and a custom vulkan example correctly. I don't really see anything off about the line it's erroring on (just a simple swapchain setup)

I am currently using the nvidia-open drivers, which might have to do with it, due to a system error in arch under 550, but I assume a lot of us are doing this right now.

Attached the full error and my vulkaninfo, but will continue to look

Panics in submit when running under X11

After the zed launch, we're seeing a number of crashes in ::submit:

Aquire image error ERROR_SURFACE_LOST_KHR
GPU has crashed, and no debug information is available.

It seems like these are exclusive (or at least very much more common) on Zed's X11 implementation vs the Wayland one, so I wonder if we've messed something up on our side.

I haven't seen this locally, but it happens across a wide range of linux distributions in the wild.

Do you have an idea for what I should look for to try and debug this?

Is web supported?

In the talk delivered a year ago you showed a wasm demo, but I found this line in the docs:

https://github.com/kvark/blade/blame/6e2103583478366084be68456d82acf50dfb283d/blade-graphics/etc/FAQ.md#L5

Is it outdated? How well supported is web compared to native?

[Zed] ERROR_INCOMPATIBLE_DRIVER

Arch Linux, up to date| linux 6.9.2 | Wayland | GNOME 46 | Ryzen 5 5600U with integrated Radeon graphics

Zed installed through the zed-editor-git AUR package. This package do works as I'm using it daily on another computer. I originally tried to transfer the compiled archive from my main computer to this one, and then built it directly. Same result for both:

$ Zed
Thread "main" panicked with "called `Result::unwrap()` on an `Err` value: ERROR_INCOMPATIBLE_DRIVER" at [scrubbed]/blade-b2bcd1de1cf7ab6a/bdaf8c5/blade-graphics/src/vulkan/init.rs:346:55

Since it is related to a blade assertion, I thought it would be faster to start the issue here.
I honestly don't know much about graphics stack and so on, so I'm a little lost on the information required here.

Window transparency support

There is a bit of a portability problem: Vulkan/Mesa supports VK_COMPOSITE_ALPHA_PRE_MULTIPLIED_BIT_KHR, while Metal supports VK_COMPOSITE_ALPHA_POST_MULTIPLIED_BIT_KHR.

We don't want to do an extra full-screen pass, and we don't control the pipelines of the user.
So perhaps we could request transparency and then get one of the modes back:

#[derive(Debug)]
pub struct SurfaceConfig {
    ...
    transparent: bool,
}


enum AlphaMode {
  Ignored,
  PreMultiplied,
  PostMultiplied,
}

struct SurfaceInfo {
  format: TextureFormat,
  alpha: AlphaMode,
}

fn resize(&self, config: SurfaceConfig) -> SurfaceInfo {...}

Then the user of the library can do the pre (or post) multiplication themselves in the shader.

Full Ray Traced Scene

We need to demonstrate an ability to load whole 3D scenes and render them in real-time with ray-tracing.
Even though #6 has paved the way to ray tracing, and there is a ray query example now, there is still a few hard steps to make for this to work on complex scenes.

Main steps:

Bonus:

asset cache (potentially with distill)
taskification (likely with choir)

First of all, there needs to be a blade-render crate that takes care of scene resources, BLAS/TLAS, pipelines, and associated buffers. The user would still be in control of encoding the commands, but the renderer would do all the heavy lifting of ray-tracing.

Secondly, we need to find a way for the ray intersection code to fetch the associated object data: vertex/index buffers, material parameters, etc. This is generally done via the device address buffer (and potentially SBT) in Vulkan, but here we have to also make it compatible with Metal. So far, it looks like the only way there is via converting everything to use Metal Argument Buffers. So we'd start by doing the work on Naga side.

Potentially, we'd first get Vulkan running with blade-render, and then focus on ramping up Metal side. There is still a question of what type would be used for the array bindings, since &[BufferPiece; N] is apparently not liked by the orphan rules:

Windows: Disable exclusive fullscreen mode

I was working on a fullscreen implementation at zed-industries/zed#9728 and ran into a problem where it would automatically go into exclusive fullscreen mode, and it needed to use VK_EXT_full_screen_exclusive to fix this.

kazatsuyu@662787b
This is my quick implementation and I have confirmed that it works, but I don't know much about blade internals and don't have a lot of knowledge of Vulkan, so I would need to consult with you on how to implement it.

	let is_vulkan_portability =
	supported_instance_extensions.contains(&vk::KhrPortabilityEnumerationFn::name());

	if is_vulkan_portability {
	device_extensions.push(vk::KhrPortabilitySubsetFn::name());
	}
