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.

Build Instructions

In order to build vitaGL use the following command: make HAVE_SBRK=1 install. If you already have a newlib sbrk replacement in your app (eg. RetroArch), use instead this command: make install.
These are all the available flags usable when compiling the library:
HAVE_SBRK=1 Enables internal custom implementation for sbrk.c from newlib.
HAVE_SHARK_LOG=1 Enables logging support in runtime shader compiler.
LOG_ERRORS=1 Errors will be logged with sceClibPrintf.
LOG_ERRORS=2 Errors will be logged to ux0:data/vitaGL.log.
NO_DEBUG=1 Disables most of the error handling features (Faster CPU code execution but code may be non compliant to all OpenGL standards).
SOFTFP_ABI=1 Compiles the library in soft floating point compatibility mode.
HAVE_UNFLIPPED_FBOS=1 Framebuffers objects won't be internally flipped to match OpenGL standards.
SHARED_RENDERTARGETS=1 Makes small framebuffers objects use shared rendertargets instead of dedicated ones.
CIRCULAR_VERTEX_POOL=1 Makes temporary data buffers being handled with a circular pool.
SAMPLER_UNIFORMS=1 When enabled, shader samplers are treated as uniforms.
