Vello Alternatives

vello reviews and mentions

• Rive Renderer – now open source and available on all platforms
  7 projects | news.ycombinator.com | 20 Mar 2024

  I'm looking forward to doing careful benchmarking, as this renderer absolutely looks like it will be competitive. It turns out that is really hard to do, if you want meaningful results.

  My initial take is that performance will be pretty dependent on hardware, in particular support for pixel local storage[1]. From what I've seen so far, Apple Silicon is the sweet spot, as there is hardware support for binning and sorting to tiles, and then asking for fragment shader execution to be serialized within a tile works well. On other hardware, I expect the cost of serializing those invocations to be much higher.

  One reason we haven't done deep benchmarking on the Vello side is that our performance story is far from done. We know one current issue is the use of device atomics for aggregating bounding boxes. We have a prototype implementation [2] that uses monoids for segmented reduction. Additionally, we plan to do f16 math (which should be a major win especially on mobile), as well as using subgroups for various prefix sum steps (subgroups are in the process of landing in WebGPU[3]).

  Overall, I'm thrilled to see this released as open source, and that there's so much activity in fast GPU vector graphics rendering. I'd love to see a future in which CPU path rendering is seen as being behind the times, and this moves us closer to that future.

• WebKit Switching to Skia for 2D Graphics Rendering

• Looking for this. html + css rendering through wgpu.
  14 projects | /r/rust | 3 Jul 2023

  Dioxus is working on this with blitz. It's leveraging wgpu through the linebender group's Vello renderer. Still in early stages.

• A note on Metal shader converter

  If you're doing advanced compute work (including lock-free data structures), then it's best effort.

  https://github.com/linebender/vello/issues/42 is an issue from when Vello (then piet-gpu) had a single-pass prefix sum algorithm. Looking back, I'm fairly confident that it's a shader translation issue and that it wouldn't work with MoltenVK either, but we stopped investigating when we moved to a more robustly portable approach.

• Vello: An experimental WebGPU-based compute-centric 2D renderer in Rust

  There are a number of up-and-coming Rust-based frameworks in this niche:

  - https://github.com/iced-rs/iced (probably the most usable today)

  - https://github.com/vizia/vizia

  - https://github.com/marc2332/freya

  - https://github.com/linebender/xilem (currently very incomplete but exciting because it's from a team with a strong track record)

  What is also exciting to me is that the Rust GUI ecosystem is in many cases building itself up with modular libraries. So while we have umpteen competing frameworks they are to a large degree all building and collaborating on the same foundations. For example, we have:

  - https://github.com/rust-windowing/winit (cross-platform window creation)

  - https://github.com/gfx-rs/wgpu (abstraction on top of vulkan/metal/dx12)

  - https://github.com/linebender/vello (a canvas like imperative drawing API on top of wgpu)

  - https://github.com/DioxusLabs/taffy (UI layout algorithms)

  - https://github.com/pop-os/cosmic-text (text rendering and editing)

  - https://github.com/AccessKit/accesskit (cross-platform accessibility APIs)

  In many cases there a see https://blessed.rs/crates#section-graphics-subsection-gui for a more complete list of frameworks and foundational libraries)

• Drawing and Annotation in Rust
  1 project | /r/rust | 8 Mar 2023

  blessed.rs lists these three crates for 2D drawing: - https://lib.rs/crates/femtovg - https://lib.rs/crates/skia-safe - https://github.com/linebender/vello

• Recommended UI framework to draw many 2D lines?
  5 projects | /r/rust | 6 Mar 2023

  Vello (https://github.com/linebender/vello) which uses wgpu to render Edit: just saw you require images. Vello doesn't support those yet

• Announcing piet-glow, a GL-based implementation of Piet for 2D rendering
  3 projects | /r/rust | 6 Mar 2023

  How does this relate to Vello? Both target raw-window-handle for winit compatibility. Vello uses WGPU vs piet-glow using GL.

• Is WGPU actually a good idea yet?
  1 project | /r/rust_gamedev | 1 Mar 2023

  Finally, maybe vello could help you with ideas. It's not production ready yet, but they have some interesting ideas for 2D rendering using wgpu.
