The presentation covers an overview about the importance of cross-platform development for 3D content. The frameworks Qt and OpenKODE and WebGL are introduced and compared to each other. It also provides information about the different OpenGL ES versions and which mobile devices support them. For more detailed information on this topic, the paper can be read.
