LibreOffice 4.3 now supports inserting 3D models in the glTF format into presentations (using libgltf). Currently this feature is only available for Linux and Windows. There is also limited support for 3D models in .dae and .kmz formats using collada2gltf.
MulticoreWare has been instrumental in help push more than fifty commits into the core code-base today for the LibreOffice open-source office suite. These commits are work on support for “GPU Calc” to take advantage of OpenCL for various math spreadsheet calculations. The OpenCL changes should be apart of the LibreOffice 4.2 release due out in late January or early February.
LibreOffice is a well-liked office suite, but not so much its spreadsheet component, Calc, which is known to be slow for even simple calculations. Now AMD has stepped in to provide GPU support that should speed things along. It seems that the LibreOffice programmers are trying to make the code fit in with AMDs Heterogeneous Systems Architecture (HSA) but the code itself is going to be written in OpenCL. This brings some hope that the optimizations might work with other GPUs such as NIVIDA’s.
