Hi. Thank you so much for playing my game. This is a short simplified explanation on how the game draws the final image onto the screen:
Essentially the basic scene without any post processing effects is first drawn onto a 100x75 texture. After that I draw a 100x75 grid of quads(so 7500 quads each with area of 64 pixels using instanced drawing) onto the 800x600 screen. Each quad gets a color sampled from the texels of the scene texture and a texture of a white letter with a transparent background determined by the color from the scene. The texture of the letter then gets sampled and multiplied with the color from the sampled scene texture which determines the color of the final fragments. This then results into the final image shown on the screen. Sorry if the explanation is a bit hard to understand. English is not my first language : )
Also yes the game was supposed to have a fullscreen button and mobile touch support but these things were dropped because of time constraints. The whole thing including a lot of the framework was done in about a week. The fullscreen button would actually be a really easy thing to add so I might add that when I get the time.
Anyway thank you for taking your time to comment and play my game : )
