Release of v2.7.0

Version 2.7.0: Released March 4th, 2023

• Changes in libraries:
  • \ref mrpt_gui_grp
    • All OpenGL viewports: pan is now also achieved by pressing the mouse middle button (wheel) + dragging, for similarity with many other CAD UIs.
  • \ref mrpt_opengl_grp
    • Shadows can now be rendered for directional lights. See mrpt::opengl::Viewport::enableShadowCasting()
    • These class names have been shortened for ease of use (typedefs with the older names still exist for backwards compatibility, including deserialization of old files):
      • mrpt::opengl::COpenGLScene ==> mrpt::opengl::Scene
      • mrpt::opengl::COpenGLViewport ==> mrpt::opengl::Viewport
    • New class mrpt::opengl::CSkyBox for rendering "3D background" as sky boxes. Refer to example \ref opengl_skybox_example
    • OpenGL shaders: more rational use of GLSL precision specifiers: highp for positions, lowp for colors.
    • New flag mrpt::opengl::CFBORender::Parameters::raw_depth
    • mrpt::opengl::FrameBuffer: Remove stencil bit for faster off-screen rendering.
    • New class mrpt::opengl::OpenGLDepth2LinearLUTs
    • mrpt::opengl::CMesh now supports texture wrapping over the mesh extension.
    • Texture handling refactored into a new class mrpt::opengl::Texture
    • Enabled GL MipMap texture generation.
    • Triangles shaders now also account for shininess of material to generate specular reflections. See new method mrpt::opengl::CRenderizable::materialShininess()
    • mrpt::opengl::TLightParameters has been modified to make it more consistent: just one light color and three floats (diffuse, ambient, specular).
    • mrpt::opengl::CRenderizable base methods are now 100% thread-safe. getPoseRef() method has been removed since it was not safe.
• BUG FIXES:
  • Fix unrealistic odometry error simulation in mrpt::kinematics::CVehicleSimulVirtualBase (it affected the app GridmapNavSimul).

  • clang-format: enforce and upgraded to use clang-format-11.
• BUG FIXES:
  • Fix crash if calling mrpt::opengl::CSetOfObjects::getByName() with null pointers as children objects.

Release of v2.5.6

Version 2.5.6: Released November 12th, 2022

• Changes in libraries:
  • \ref mrpt_containers_grp
    • New template class mrpt::containers::PerThreadDataHolder
  • \ref mrpt_opengl_grp
    • The rendering pipeline (mrpt::opengl::enqueueForRendering) is now more optimized to cull earlier, achieving faster rendering of large and complex 3D scenes.
    • All opengl shaders, objects, and renderers are now multithread capable, including rendering several FBOs in different threads.
    • mrpt::opengl::CFBORender constructor now takes a parameters struct making it much more configurable.
    • mrpt::opengl::CAssimpModel now supports (de)serializing, storing itself in the Assimp binary format (assbin).
    • New opengl shaders: one set for light-enabled objects and another for objects without diffuse reflection effects (to avoid conditionals inside the GPU shader programs).
  • \ref mrpt_gui_grp
    • mrpt::gui OpenGL canvas windows and components no longer have a background color property. It is now always handled by the mrpt::opengl::COpenGLViewport to avoid duplicated functionalities.
  • \ref mrpt_system_grp
    • These functions are now thread-safe if built in a system with the localtime_r() variant of localtime():
