`iced_glow`

iced_glow is a [glow] renderer for [iced_native]. This renderer supports OpenGL 3.0+ and OpenGL ES 2.0.

This renderer is mostly used as a fallback for hardware that doesn't support [wgpu] (Vulkan, Metal or DX12).

Currently, iced_glow supports the following primitives: - Text, which is rendered using [glow_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. - Meshes of triangles, useful to draw geometry freely.

The native target

Installation

Add iced_glow as a dependency in your Cargo.toml:

toml iced_glow = "0.7"

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!]
