IFC Viewer 1.3.0.0
Описание
IFC Viewer is a lister plugin (WLX) for Total Commander to display IFC (Industry Foundation Classes) building model files as interactive 3-D views using OpenGL.The IFC Viewer plugin is based on the Web IFC library v0.0.77.
Supported file formats:
- IFC (STEP Physical File)
- IFCZIP (ZIP-compressed IFC)
Features:
- 3-D OpenGL rendering of IFC geometry with lighting
- Texture support (IfcImageTexture, IfcBlobTexture, IfcPixelTexture)
- Entity tree panel showing the spatial structure of the model (Project > Site > Building > Storey > elements); single-click highlights an element in orange, double-click or Enter zooms the view to it. The panel width is adjustable by dragging the splitter seam between the 3-D view and the panel.
- Mouse interaction: left-drag to rotate, right-drag to pan, wheel to zoom
- Double-click to reset the view
- Keyboard shortcuts for toggling diagnostics (D), view modes (G), projections (O), properties overlay (B), status bar (S) and entity tree (T)
