Viewer for 3D STL files, classic image viewer controls, OpenGL
- Allow to compensate the extrusion pattern by thinning or widening the model
- I.E. If the extruder overextrude by 0.10mm in the X axis, a -0.10mm offset can be applied on the faces
- This is not the same as scaling as it preserve the actual overall dimensions and positions
- Controls for all 3 axis
- Save to a new STL binary file, preserving colors, with data/time/compensation markers
- Binary STL
- ASCII STL
- Color STL (per facet encoded in attribute word)
- Some oddball hybrid binary with ASCII header files
- Display a wireframe build volume
- Auto center model in view
- Left and Right arrows for Previous and Next model in folder
- Ctrl-R to rename file
- C to toggle default color vs model colors
- W to toggle wireframe mode
- Delete to move file to trash
- F11 to activate "center feature" size compensation controls (Ctrl+S to save)
- F12 to activate model compensation controls (Ctrl+S to save)
Build volume dimensions and default color can be set in the ".config" file.
- Base branch uses OpenTK OpenGL 2.0 immediate mode and compiled lists: context takes about a second to initialize.
- Parallel branches to test faster and more modern contexts
- 4.x OpenGL with shaders and VBO
- WPF native 3D rendering context
- AlgoOptimization
Algorithms are now in O(nlog(n)) and linear instead of the naive O(n^2) implementation
