iced/wgpu

iced_wgpu

iced_wgpu is a wgpu renderer for iced_runtime. For now, it is the default renderer of Iced on native platforms.

wgpu supports most modern graphics backends: Vulkan, Metal, and DX12 (OpenGL and WebGL are still WIP). Additionally, it will support the incoming WebGPU API.

Currently, iced_wgpu supports the following primitives:

• Text, which is rendered using wgpu_glyph. No shaping at all.
• Quads or rectangles, with rounded borders and a solid background color.
• Clip areas, useful to implement scrollables or hide overflowing content.
• Images and SVG, loaded from memory or the file system.
• Meshes of triangles, useful to draw geometry freely.

Installation

Add iced_wgpu as a dependency in your Cargo.toml:

iced_wgpu = "0.10"

Iced moves fast and the master branch can contain breaking changes! If you want to learn about a specific release, check out the release list.

Current limitations

The current implementation is quite naive; it uses:

• A different pipeline/shader for each primitive
• A very simplistic layer model: every Clip primitive will generate new layers
• Many render passes instead of preparing everything upfront
• A glyph cache that is trimmed incorrectly when there are multiple layers (a glyph_brush limitation)

Some of these issues are already being worked on! If you want to help, get in touch!
