প্রকল্প সম্পর্কে

langterm is a WebGL-based VT220 terminal emulator with a "fancy" pseudo-CRT mode and a "simple" fallback for small screens, touch events, or missing WebGL. The Terminal data structure tracks logical screen state and is rendered into a 2048x2048 texture using an Apple II bitmap font sprite sheet; a full-screen quad then applies scanline and warping post-processing adapted from Timothy Lottes' CRT shader. Text input is buffered and sent on Enter to a separate glulxe-httpd interactive fiction server running an Inform7 story. The README notes it was built from WebGL Boilerplate, serves as the author's home page, and the repository source is MIT licensed while bundled fonts, photos, and shaders remain under original author licenses.
