way to display text

None · 2020-12-03T16:14:24

previously (with my DX9 render) I had each letter as a separate texture, at runtime I had these letters textures applied/changed at on a wall made of (fixed) squares like airport old fashion panels used to to announce arrivals/departures. Now I want to use one large texture containing all the letters and then play with the texture coordinates on the square to display the right letter. My question is do I need to use a separate vertex buffer for each square (4 vertices)? a lot of text means a huge pile of vertex buffers that I need to generate at run time, it also means I have to translate these in the right position.
