DeepSea Text manages drawing of arbitrary Unicode text with standard fonts. Rendering is performed using the signed distance field method, allowing a wide range of scaling with the same glyph textures.
One or more fonts are loaded using dsFaceGroup. A dsFont is created with fonts loaded from the dsFaceGroup, allowing for support of international text. If a glyph isn't available in one font, it will try the next until it is found.
Once a font has been created, it can be used along with a Unicode string to create a dsText instance. This will do the initial calculations required to draw the text. A dsTextLayout object can then be created to apply styling information to compute the geometry that can be rendered. Rendering is typically performed with the dsTextRenderBuffer helper object. The vertex format is provided for the text geometry, and a callback is used to provide the vertex information for each glyph. A dsTextRenderBuffer object can be used to combine multiple dsTextLayout objects into a single draw call.
A shader must be provided and bound to perform drawing of text. When writing shaders, the dsComputeTextDistance() and dsComputeTextColor() functions in Text.mslh can be used to compute the final text color, while the texture containing glyph information can be queried from the dsFont instance. The texture containing the fonts Examples can be found in testers/TestText/Font.msl and testers/TestText/FontTess.msl for drawing standard quads and generating quads with a tesselation shader, respectively.
