Detailed Description

Describes how to draw a character from the font texture map.

The relevant quantities are:

• Texture coordinates
  • u0, v0 : top left of character
  • u1, v1 : bottom right of character
• Vertex offsets
  • x0, y0 : top left vertex offset
  • x1, y1 : bottom right vertex offset
• anchor : the nominal 3D position where the character is to be rendered
• line_height : the nominal line height in Cartesian space coordinates. Note that this is not the line height in texture coordinates.

To draw the character, draw a quad with:

• top left = (anchor.x + x0 * line_height, anchor.y + y0 * line_height, 0)
• bottom right = (anchor.x + x0 * line_height, anchor.y + y0 * line_height, 0)

Then, set anchor = (anchor.x + width_to_height * line_height, anchor.y, 0) to draw the next character.
