Today I wanted to test a little how the hardware acceleration is working in rendering 3D OpenGl ES applications on the Nokia N95. In order to do this I downloaded a sample 3D engine from the Nokia website.In order to run it on the emulator, I used Carbide VS 2005. The steps I followed were:
1. [...]

Due to the fact that OpenGL ES does not provide any kind of fonts, we need think a way to create the characters and display them efficiently.
In order to use fonts in OpenGL ES, we will use a widely used technique called: bitmapped fonts. That is, we store into a texture all characters of [...]

In order to load a texture we will use the following function :
bool LoadTexture(const char *fileName, GLuint *id)
This function will receive a texture filename and a pointer to a texture identifier. This identifier will be initialized from inside the function (if proceed). It will return true if the texture was successfully loaded, otherwise it will [...]
