VitaGL improvements with multitexturing support, VitaQuakeIII update incoming! (video)

Rinnegatamante is teasing an upcoming update for VitaQuakeIII, his Quake 3 port on the PS Vita. The Vita developer has worked on improvements to VitaGL, the openGL wrapper for the PS vita.

What is VitaGL for the PS Vita?

From the VitaGL Readme:

vitaGL is an opensource openGL driver for PSVITA development. It acts as a wrapper between openGL and sceGxm and allows to use a subset of openGL functions with fully hardware acceleration by translating the code to sceGxm equivalent.

In other words, if you’re a homebrew developer, this is an excellent library if you are attempting to port one of the many games that use OpenGL (Quake 3 being one of those), as it eliminates the need for you to write your own wrapper to the Vita’s proprietary GPU functions.

What’s coming for Vita Quake 3 ?

Rinnegatamante has implemented multitexturing support and Texture combiner (GL_COMBINE).  According to the developer, this allowed to use Quake3’s original shading code (which uses multitexturing), which improves performance and fixes some glitches. Check the video below
