Since version 0.8.0, GLSL Hacker comes with a new plugin based on FreeType-GL, that allows to load any TTF (True Type Font) or OTF (Open Type Font) font file. I also added a Lua layer in GLSL Hacker libs folder to make font management even easier (libs/lua/gx_font.lua).
Time to time, when I find an interesting font, I do a test, just to be sure that the plugin is able to handle it. I just tested this font and tried to reproduce their example with GLSL Hacker.
This GLSL Hacker demo is available in the code sample pack (host_api/freetype-gl/demo_gl3_v3.xml).
This demo use the high level Lua lib (gx_font.lua) to handle fonts.
INIT script:
lib_dir = gh_utils.get_scripting_libs_dir() dofile(lib_dir .. "lua/gx_font.lua") local demo_dir = gh_utils.get_demo_dir() font1 = ftgl_load_font_v2(demo_dir .. "data/CODE Bold.otf", 160, 2, 1) font2 = ftgl_load_font_v2(demo_dir .. "data/CODE Light.otf", 160, 1, 2) gh_renderer.set_vsync(1) gh_renderer.set_depth_test_state(1)
FRAME script:
elapsed_time = gh_utils.get_elapsed_time() gh_renderer.clear_color_depth_buffers(0.0, 0.0, 0.0, 1.0, 1.0) ftgl_begin(font2) ftgl_print(font2, 20, 160, 1, 1, 1, 1, "GEEKS3D") ftgl_end(font2) ftgl_begin(font1) ftgl_print(font1, 20, 290, 0.8, 0.8, 0.9, 1.0, "GLSL") ftgl_print(font1, 20, 420, 0.5, 0.5, 0.6, 1.0, "HACKER") ftgl_end(font1)
TERMINATE script:
ftgl_kill()
SIZE script:
winW, winH = gh_window.getsize(0) ftgl_resize(winW, winH)
