Description

Description

Currently, the OpenROAD 3DBlox 3D Viewer only displays chiplets as solid boxes (along with DRC markers). There is no support for rendering inter-chip wiring, bumps, or TSVs (Through Silicon Vias). While bumps are visible in the 2D viewer as COVER_BUMP instances, TSVs lack dedicated support in either viewer.

This feature request is to add 3D rendering support for these interconnect elements to improve the 3D visualization capabilities.
