:
A simple 2D graphics library for turning simple 2D shapes and text into textured triangles.
Made for egui
.
Create some Shape
:s and pass them to tessellate_shapes
to generate Mesh
:es
that you can then paint using some graphics API of your choice (e.g. OpenGL).
Coordinate system
The left-top corner of the screen is (0.0, 0.0)
,
with X increasing to the right and Y increasing downwards.
epaint
uses logical points as its coordinate system.
Those related to physical pixels by the pixels_per_point
scale factor.
For example, a high-dpi screen can have pixels_per_point = 2.0
,
meaning there are two physical screen pixels for each logical point.
Angles are in radians, and are measured clockwise from the X-axis, which has angle=0.
