Rendering ASCII smooth lines using character subdivision
I worked on rendering smooth lines in ASCII art using character subdivision.
Each character is subdivided into rounding positions to determine the entry and exit points of a line.
I’ve added 65 special characters to the Jgs font corresponding to these junction points.
I used line equations like y = slope * (x - aX) + aY and sort functions to find these in and out between two given points to render these smooth lines. And because I am very bad at maths this step took me almost an entire week…
This feature should be very useful for road rendering in The Wind Through the Wheels, in particular finally being able to render road crossings in the player’s path.
