dutch-blunt

Low poly font (plus rendering system.) Uses triangles not textures, for always sharp edges.

Sample use of font

The Font

Dutch-Blunt is both the name of the minimalistic font that I created, and its rendering API. The font was created with the following criteria:

  • Rendered as pure triangles as opposed to curves, textures, or lines.
  • Low polygon (triangle) count for each glyph.
  • ASCII only (characters 33 to 127 inclusive.)

The API

The font was created in Wings3D and exported to Wavefront OBJ. Dutch-Blunt comes with a python script that will read the wavefront OBJ file and create C-source code. The glyph data containst glyph widths, the triangle vertices, the vertex count, and an offset into a global vertex data set.

A C interface is provided to convert an ASCII string into triangle vertices that can be fed into e.g. OpenGL.

/*!
 * Convert an ascii string to a stream of vertex data.
 * Returns the number of triangles(x,y,x,y,x,y) written to the buffer.
 */
int dblunt_string_to_vertices
(
        const char* str,                //!< characters to render.
        float* destbuf,                 //!< output buffer to hold vertices.
        int destbufsz,                  //!< size of output buffer in bytes.
        float posx, float posy,         //!< target position for text render.
        float sclx, float scly,         //!< scale of the text render.
	float fadestart,		//!< if >=0, start fading out at this character number and write opactities.
        int* textw,                     //!< out: width of longest line.
        int* texth                      //!< out: height of text.
);
