We’ve also fixed bugs in OpenGL ES on Android/iOS and in EGL based offscreen hardware accelerated rendering. ![]() In 7.1 there are numerous minor updates to OpenGL2 including better management of resources with multiple windows, better support for line integral convolution, faster Composite PolyData Mapper renders, line stipple support for Context2D charts, and better support for Intel HD2000/3000 based systems on Windows. Rendering was the focus of VTK 7.0, so we shall begin there. To get started using it, git clone it or get it from the download page, and maybe check out the VTK upgrade report. We recommend that all VTK users update to 7.1. Even the code and documentation style has been significantly updated in this “minor” release. ![]() Besides rendering, there are substantial changes to web (supporting javascript has been refactored into an external repository), filtering (revised zero copy arrays and SMP image processing filters), annotation, IO (efficient parallel file system operations), chemistry, and build system (laying groundwork for move to c++11). You might be tempted to think that 7.1 is just a minor release that tweaks the rendering after the big update that took effect last year in 7.0, but you would be wrong. The VTK development team is pleased to introduce VTK 7.1.0. ![]()
