iced/glow

iced_glow

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

This is 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.

Installation

Add iced_glow as a dependency in your Cargo.toml:

iced_glow = "0.2"

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!
