New Features
Export wireframe tessellation in JT
The wireframe tessellation stored in A3DRiPolyWireData can now be exported in JT 8.1, 9.5 and 10.0 using the option m_bWriteWireframe from A3DRWParamsExportJTData (this option is set to false by default).
T-Junctions Detection and Removal
A T-junction occurs when two adjacent triangles subdivide the edge of a third triangle, hence forming T-shaped edge junction. T-junctions can cause issues in rendering, such as visible seams and cracks, or problems in simulations and mesh deformations due to the lack of proper vertex connections, leading to geometric inconsistencies.
We now provide a way to repair mesh geometry by removing T-junctions.
This new feature is provided as experimental (see Experimental Features below). It extends the HOOPS Exchange API with a new function and structure:
For more information, see T-Junctions Detection and Removal.
Experimental Features
A new API mechanism is provided to enable experimental API functions. For more information, see Extending HOOPS Exchange.
