Abstract
A system and method for rendering text data in web applications is provided that eliminates redundant processing. Constant resources are pre-computed and work is offloaded from the central processing unit to the graphics processing unit. This is generally accomplished by pre-computing before any rendering. A generic index vertex buffer object is created, and for each font, a glyph texture object and glyph position texture object are created. A frame including text is then rendered in which a glyph string texture object is created. For each character, a glyph index-to-texture and glyph offset to-texture is appended. A glyph texture, glyph position texture and glyph string texture are then bound, and the generic index vertex buffer object using a custom vertex shader is rendered.
