How to work with mesh?

Gibbz · February 16, 2025, 12:19pm

Ive been trying to hobble a ribbon effect via a canvas. But now I find its not the right tool for the job. I want to change the width of the ribbon and change colors over time.

This should be much easier using a mesh and some simple vector math…
How do i get started using the mesh in iced?
Are there any examples around?
Can I replace my canvas with a mesh surface?

Found some little snippets to get me going:

Rendering of `Mesh`es seems to break depending on the order they are added

### Is your issue REALLY a bug? - [X] My issue is indeed a bug! - [X] I am n…ot crazy! I will not fill out this form just to ask a question or request a feature. Pinky promise. ### Is there an existing issue for this? - [X] I have searched the existing issues. ### Is this issue related to iced? - [X] My hardware is compatible and my graphics drivers are up-to-date. ### What happened? If a `Mesh` that has a clip bound with a dimension below 1 pixel is drawn before another `Mesh` with a larger clip bound, the second is not drawn. Minimum example: ```rs use iced::{ advanced::{ graphics::{ color, mesh::{self, Renderer as _, SolidVertex2D}, Mesh, }, layout::{Limits, Node}, renderer::Style, widget::Tree, Layout, Widget, }, mouse::Cursor, Length, Rectangle, Renderer, Size, Theme, Transformation, }; fn main() { iced::application("", App::update, App::view).run().unwrap(); } struct App; #[derive(Debug)] enum Message {} impl App { fn new() -> Self { Self } fn update(&mut self, _: Message) {} fn view(&self) -> iced::Element<'_, Message> { iced::Element::new(Test) } } impl Default for App { fn default() -> Self { Self::new() } } struct Test; impl Widget<Message, Theme, Renderer> for Test { fn size(&self) -> Size<Length> { Size::new(Length::Fill, Length::Fill) } fn layout(&self, _tree: &mut Tree, _renderer: &Renderer, limits: &Limits) -> Node { Node::new(Size::new(limits.max().width, limits.max().height)) } fn draw( &self, _tree: &Tree, renderer: &mut Renderer, theme: &Theme, _style: &Style, _layout: Layout<'_>, _cursor: Cursor, _viewport: &Rectangle, ) { let mesh1 = Mesh::Solid { buffers: mesh::Indexed { vertices: vec![ SolidVertex2D { position: [0.0, 0.0], color: color::pack(theme.extended_palette().secondary.base.text), }, SolidVertex2D { position: [0.0, 100.0], color: color::pack(theme.extended_palette().secondary.base.text), }, SolidVertex2D { position: [100.0, 100.0], color: color::pack(theme.extended_palette().secondary.base.text), }, ], indices: vec![0, 1, 2], }, transformation: Transformation::IDENTITY, clip_bounds: Rectangle { x: 0.0, y: 0.0, width: 100.0, height: 0.9999999, }, }; let mesh2 = Mesh::Solid { buffers: mesh::Indexed { vertices: vec![ SolidVertex2D { position: [0.0, 100.0], color: color::pack(theme.extended_palette().secondary.base.text), }, SolidVertex2D { position: [0.0, 200.0], color: color::pack(theme.extended_palette().secondary.base.text), }, SolidVertex2D { position: [100.0, 200.0], color: color::pack(theme.extended_palette().secondary.base.text), }, ], indices: vec![0, 1, 2], }, transformation: Transformation::IDENTITY, clip_bounds: Rectangle { x: 0.0, y: 100.0, width: 100.0, height: 100.0, }, }; renderer.draw_mesh(mesh1); renderer.draw_mesh(mesh2); } } ``` `mesh2` doesn't render here. Swapping the two `draw_mesh` calls makes `mesh2` render correctly. This affects both this release and the master branch. ### What is the expected behavior? The mesh with the large clip bound is rendered. ### Version crates.io release ### Operating System Linux ### Do you have any log output? _No response_

rendering only empty meshes crashes iced

The geometry example is good for getting to know how to use mesh

Alternatively, I use meshes here in one of my custom widgets: generic-daw/generic_daw_gui/src/widget/audio_clip.rs at main · generic-daw/generic-daw · GitHub It’s not super well documented but maybe that can be of some help as well.

great thanks! Its certainly plenty to get me going in the examples you’ve given!
