Fontes de Mapa de Bit

I think the question I get asked most often in email is "how can I display text on the screen using OpenGL?". You could always texture map text onto your screen. Of course you have very little control over the text, and unless you're good at blending, the text usually ends up mixing with the images on the screen. If you'd like an easy way to write the text you want anywhere you want on the screen in any color you want, using any of your computers built in fonts, then this tutorial is definitely for you. Bitmaps font's are 2D scalable fonts, they can not be rotated. They always face forward.

Fontes Desenhados

Bitmap fonts not good enough? Do you need control over where the fonts are on the Z axis? Do you need 3D fonts (fonts with actual depth)? Do you need wireframe fonts? If so, Outline fonts are the perfect solution. You can move them along the Z axis, and they resize. You can spin them around on an axis (something you can't do with bitmap fonts), and because proper normals are generated for each character, they can be lit up with lighting. You can build Outline fonts using any of the fonts installed on your computer. Definitely a nice font to use in games and demos.

Fontes Texturizados

Hopefully my last font tutorial {grin}. This time we learn a quick and fairly nice looking way to texture map fonts, and any other 3D object on your screen. By playing around with the code, you can create some pretty cool special effects, Everything from normal texture mapped object to sphere mapped objects. In case you don't know... Sphere mapping creates a metalic looking object that reflects anything from a pattern to a picture.

Fontes Simples com Texturas 2D

The original version of this tutorial code was written by Giuseppe D'Agata. In this tutorial you will learn how to write any character or phrase you want to the screen using texture mapped quads. You will learn how to read one of 256 different characters from a 256x256 texture map, and finally I will show you how to place each character on the screen using pixels rather than units. Even if you're not interested in drawing 2D texture mapped characters to the screen, there is lots to learn from this tutorial. Definitely worth reading!
