gfx_glyph

Fast GPU cached text rendering using gfx-rs & rusttype.

Makes use of three kinds of caching to optimise frame performance.

• Caching of glyph positioning output to avoid repeated cost of identical text rendering on sequential frames.
• Caches draw calculations to avoid repeated cost of identical text rendering on sequential frames.
• GPU cache logic to dynamically maintain a GPU texture of rendered glyphs.

```rust extern crate gfxglyph; use gfxglyph::{Section, GlyphBrushBuilder};

let garamond: &[u8] = includebytes!("GaramondNo8-Reg.ttf"); let mut glyphbrush = GlyphBrushBuilder::usingfontbytes(garamond) .build(gfx_factory.clone());

let section = Section { text: "Hello gfx_glyph", ..Section::default() // color, position, etc };

glyphbrush.queue(section); glyphbrush.queue(someothersection);

glyphbrush.drawqueued(&mut gfxencoder, &gfxcolor, &gfx_depth).unwrap(); ```

Limitations

The current implementation supports OpenGL (3.0 or later). However, other rendering languages (that are supported by gfx) should be easy enough to add. Send in your PRs!
