Easy3D-v2.5.4

Changes

• added a simple application PictureMaker. It can be used to generate figures for visual comparison of models (useful for paper writing).
• the layout of MultiViewer can now be changed dynamically.
• vertex/face properties in the 'decompose' and 'merge' functions in Mapple are well preserved.
• allows for the handling of colors in both [0, 255] and [0, 65535] for las and laz file formats.
• consistent GLSL versions in shaders.
• fixed various bugs and warnings.

Easy3D-v2.5.3

Changes

• Added support to the MinGW compiler.
• The OBJ format loader can handle per-vertex color attributes.
• Added a few matrix algorithms (SVD, inverse, determinant, least squares solver).
• Kd-trees can be created from an array of 3D points (not only PointCloud).
• Added a function to compute the perpendicular feet of two 3D lines.
• More robust face normal calculation for concave faces in SurfaceMesh.
• Added algorithms for convex partition of polygons.
• Added screen-constrained manipulation (rotation and translation).
• Added Viewer::bind(...) and Viewer::set_usage(...) for easier executing user functions.
• Fixed various bugs and warnings.

Easy3D-v2.5.2

Changes:

• unified naming for classes, namespaces, and files
• simplified initialization
• changes in the names of a few files and namespaces (see the breaking changes below)

Breaking changes:

• the file version.h/version.cpp and thus the following functions have been moved to the util module:
  • easy3d::version_major()
  • easy3d::version_minor()
  • easy3d::version_patch()
  • easy3d::version()
• the following namespaces have been renamed:
  • buffers -> buffer
  • shapes -> shape
• the following files have been renamed:
  • buffers.h/buffers.cpp -> buffer.h/buffer.cpp
  • shapes.h/shapes.cpp -> shape.h/shape.cpp
• the following function has been moved to namespace easy3d::geom (see here):

  bool intersect(const GenericPlane<FT> &plane1, const GenericPlane<FT> &plane2, const GenericPlane<FT> &plane3,
                      typename GenericPlane<FT>::Point3 &point);

Easy3D-v2.5.1

New features:

• support installation
• support shared libraries

Breaking change:

• the following functions/variables have been moved to the util module. See easy3d/util/resources.h:
  • resource::directory()
  • resource::bunny_vertices
  • resource::bunny_indices

Easy3D-v2.5.0

Main changes:

• (breaking change) renamed class OpenglInfo to OpenglUtil.
• added a viewer based on wxWidgets (see here).
• added a few new functions and various bug fixes and improvements.

Pre-built binaries are not changed (i.e., you can still use the previous version v2.4.7).

Easy3D-v2.4.9

Main changes:

• simplified the use of kd-tree (Breaking change).
• PrincipalAxes has only one template parameter. It uses double internally for higher precision.
• added a virtual scanner to the examples.
• various minor bug fixes and improvements.

Pre-built binaries are not changed (i.e., you can still use the previous version v2.4.7.

Easy3D-v2.4.8

Main changes:

• introduced a new composite viewer class CompViewer, which supports multiple views arranged in a grid layout in the same window. See here for example usage.
• introduced usage_string_ and execute_func_, which eases the use of the viewer for running an algorithm.
• various minor bug fixes and improvements.

Pre-built binaries are not changed (i.e., you can still use the previous version.

Easy3D-v2.4.7

• compatible with Apple Silicon Processors (memory allocation functions in third-party library RANSAC).
• support geojson format.
• update third-party libraries glfw and imgui to their latest versions.
• add "rotate-around-axis" mode for keyframe animation.
• various bug fixes.

Easy3D-v2.4.6

• minor bug fixes
• support old deprecated camera state format (*.state)
• update information for citation

Easy3D-v2.4.5

• added a test suite
• corrected license and copyright information for several mesh processing algorithms
• more fault-tolerant to PLY variants
• several minor bug fixes
