Android downloadable fonts opengl

 · I'm currently developing a small OpenGL game for the Android platform and I wonder if there's an easy way to render text on top of the rendered frame (like a HUD with the player´s score etc). The text would need to use a custom font also. Ada Fonts is a minimalistic example of using freetype fonts in OpenGL Ada applications using Felix Krause's FreeTypeAda package It is intended to be the modern version of the "glut font" demos from a previous era. It also uses Stephen Sangwine's PNG-IO package, and thin bindings to OpenGL, SDL2. More importantly, it shows how to encapsulate the scripts and runtime libraries necessary to easily .  · Draw text in OpenGL ES. I thought I could use this technique in order to dynamically display text (say an FPS counter). I realised that calls to resources to get the drawable slows down this process quite a lot, and I didn't need a bitmap background, so I removed it. The technique works, but after a while (~ frames) the whole phone locks bltadwin.rus: 4.

I'm currently developing a small OpenGL game for the Android platform and I wonder if there's an easy way to render text on top of the rendered frame (like a HUD with the player´s score etc).

Figure 3. Selecting font from the Resources window. Android Studio automatically generates the relevant XML files that are needed to render the font correctly in your app. Figure 4.

OpenGL textures need to have dimensions that are powers of two, so we need to pad the font bitmaps created by FreeType to make them a legal size. That's why we need this function: // This Function Gets The First Power Of 2 = The // Int That We Pass It. inline int next_p2 (int a) { int rval=1; // rval<<=1 Is A Prettier Way Of Writing rval*=2; while(rval
