• camera3d -- camera and functions for 3D transforms
• color -- color constants and utilities
• graphics -- general graphics types and functions
• info -- write glutin and glium context info
• init -- glium initialization
• mesh -- mesh generation
• render -- glium-based rendering support

• texture -- blending functions and texture loading
• tile -- utilities for dealing with character-based tile/glyph data
• vertex -- vertex specifications

Running tests

Note documentation tests may have linker failure when running too many tests concurrently (observed with 7 or more test threads). Use cargo test -- --test-threads=6 (or fewer threads) to avoid this problem.

Notes on windowing and context creation backends

winit

as of v0.30.5, winit has an x11 feature and a wayland feature; both are default features

glutin

as of v0.32.1, glutin has features for the following windowing system interfaces:

• egl
• glx
• wgl

it also has features x11 and wayland

all the above features are included in default features

glutin-winit

as of v0.5, glutin-winit has the same features as glutin, and choosing x11 or wayland will enable the corresponding feature in winit

all the above features are included in default features

glium

as of v0.36, glium includes in default features the above dependencies with default features

this crate (gl-utils) depends on a fork of glium that does not include the default features of glutin/winit dependencies. instead it adds features x11 and windows that selectively enable the features for those platforms.
