Hi, The latest release notes of pyOpenGL (Feb 15, 2007) say that "Numarray support [was] reenabled". The current version is 3.0.0a6. Does anyone here know the status of the new (ctypes based) pyOpenGL ? How is the binding to ("modern") numpy ? I'm especially interested in fast memory access. So far I have to SWIG my own call to glVertexPointer to reduce the execution from about 160ms to a few ms. I think without the numpy support arrays are accessed through a very slow list protocol. (I'm just guessing in the dark.) I use pyOpenGL with great pleasure to display medical/microscopy images on mutli-color, color-maps using 2d-textures. It works very fast. Thanks, Sebastian
