GLisph

Quicklisp

Screen Shot

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.

(gli:init 800 600)

Load TrueType font file and make glyph table. Glyph table manages the contour points of the glyphs.

(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!

;;; 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*)

Long Description

# GLisph

[![Quicklisp](http://quickdocs.org/badge/glisph.svg)](http://quickdocs.org/glisph/)

![Screen Shot](screenshot.gif)

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*)

“‘

## Dependencies

* cl-annot
* cl-opengl
* cl-glu
* zpb-ttf
* cl-glut (optional - only required when you test GLisph)

## Installation

* Quicklisp

“‘lisp
(ql:quickload :glisph)
“‘

* Roswell

“‘bash
$ ros install glisph
“‘

* Test

“‘lisp
