Mayo is a basic 3D viewer inspired by FreeCad.
Current features are :
- Multi-documents support, user can open many parts in the session
- Support of IGES/STEP/BRep formats for import/export operations
- Support of STEP/IGES assemblies (colors and tree structure)
- Support of STL format with either OpenCascade or gmio (optional)
- Perspective/orthographic 3D view projection
- 3D clip planes with configurable capping
- Save image(snapshot) of the current 3D view
- Editable name of STEP/IGES entities
- Editable 3D properties of the imported items, eg. material, color, display mode, ...
- Area and volume properties for meshes and shapes
3D viewer operations :
- Rotate : mouse left + move
- Pan : mouse right + move
- Zoom : mouse wheel(scroll)
- Window zoom : mouse wheel + move
- Instant zoom : space bar
Mayo requires Qt5 and OpenCascade-7.2.0.
Although only tested with VC++/Windows it should build fine on Linux and MacOS.
It uses the CSF_OCCTIncludePath and CSF_OCCTLibPath environment variables to locate
OpenCascade include and lib paths. On Windows these two variables are set by the env.bat
script which can be found within OpenCascade's base folder. You should run this batch before
building mayo :
cd .../mayo
qmake
(n)make
In case you don't want to run this file you can use the CASCADE_INC_DIR and CASCADE_LIB_DIR qmake
variables instead :
qmake "CASCADE_INC_DIR=occ_include_dir" "CASCADE_LIB_DIR=occ_library_dir"
To enable optional gmio library, add this option to the qmake command line:
"GMIO_ROOT=path_to_gmio"
