Vector Texture Maps


#1

[using PowerVR MBX]

Hello,
I would like to know what’s the best techniques for vector font rendering using powervr mbx to meet suitable look/performances.

Thank you in advance.

We recommend that you generate a bitmap texture of your font and then render specific letters by generating polygons with the correct texture coordinates from this texture. This has the benefit of allowing anti-aliasing from texture filtering and is quite simple to implement.





All geometry needs to be rendered as triangles under OpenGL ES, so if vectors are essential then pre-tesselating your letters is preferable to on the fly tesselation. Efficient on-the-fly tesselation is very complicated.
