Prepare IFC geometry for glTF / GLB
The IFC-to-glTF / GLB route uses the IFC reader, mesh preparation and the glTF / GLB writer. Choose the geometry and representation required by the destination application.
Read the IFC model through the IFC interface and select the building elements needed by the recipient. Inspect the imported geometry and element placements before preparing a scene or polygonal derivative.
Prepare a scene for glTF or GLB delivery
Use existing meshes or tessellate supported imported BRep surfaces. Keep object placement consistent across the selected building model, and choose mesh detail suitable for the scale and use of the output.
Map supported model items into glTF scene nodes and configure the mesh, placements and appearance for browser or application delivery. Decide whether the receiving workflow expects a GLB package or glTF with companion resources. Keep names useful for selection and inspection.
Validate the converted model
Compare geometry coverage, unit scale and positioning. BIM relationships, classifications and property sets require explicit retention checks; a polygonal file is not a replacement for the complete IFC model.
Reopen the asset in the target viewer and compare orientation, bounds, assembly placement and visible surface quality. Check material mapping and resource paths. Measure loading cost together with geometric detail so that reducing mesh size does not silently remove required features.
For repeated jobs, retain the source, preparation settings and representative output checks. Discuss this conversion with the input files, destination application and required geometry and attributes.
