# GLisph
[](http://quickdocs.org/glisph/)
GLisph is a glyph rendering engine using OpenGL shader language. The engine draws string clearly by vector based font rendering on an OpenGL context. TrueType (TTF) is the only drawable format currently.
## Usage
Initialize the engine as below first.
“‘lisp
(gli:init 800 600)
“‘
Load TrueType font file and make glyph table. Glyph table manages the contour points of the glyphs.
“‘lisp
(defvar *font* (gli:open-font-loader "/path/to/display-font.ttf")
(defvar *glyph-table* (gli:make-glyph-table *font*))
“‘
Then you can regist and draw glyphs!
“‘lisp
;;; For CL-GLUT, you should require these display mode keywords before display-window section.
(glut:set-display-mode :stencil :multisample)
;; Before draw section
(defvar *text-buffer*
(gli:draw *glyph-table*
’(:x 120 :y 40 :size 20
:text "Hello World!"
:y 64
:text "Common Lisp")))
;;; In draw section, you can set some parameters to draw for GLisph context.
(gli:gcolor 0.8 0.2 0.5)
;;; This is rotation example.
(gli:grotate 0.0 0.0 0.5)
;; Render
(gli:render *text-buffer*)
