The KLayout roadmap includes discussions about true 3D rendering using ray marching or voxel cones. However, the maintainers (notably Matthias Koefferlein) have been cautious due to performance concerns. Most users agree: the current 25D mode hits a sweet spot.
The in KLayout is a powerful visualization tool that extrudes 2D layout layers into a 3D-like perspective. It is primarily used to inspect material stacks and vertical layer relationships, which can be difficult to visualize in a standard flat view. Core Requirements & Setup
Before diving into KLayout, we must clarify the terminology. In computer graphics, implies full six-degree-of-freedom navigation (x, y, z translation, plus roll, pitch, yaw). 2D offers only x and y. klayout 25d view

Complex volumes with unique Z coordinates for every point.
KLayout's 2.5D (often called "25D") view provides a simple and effective way to visualize layered semiconductor layouts with an embossed, height-coded representation that helps designers inspect layer stacking, overlaps, and process-related thickness information. The in KLayout is a powerful visualization tool

In the context of Electronic Design Automation (EDA), "25D" (or 2.5D) refers to a visualization method where 2D polygons are extruded vertically based on a assigned "height" and "thickness." Unlike a true 3D engine that accounts for physics, deposition, and etching angles, KLayout’s 25D view is a geometric extrusion.
Ensure your calculation of Z-start values accounts for previous layer thicknesses. For example, if Metal 1 is at with a thickness of , Via 1 should start at Conclusion
For extremely large layouts (>10 GB GDSII), create a quick 25D view by first using Hierarchy > Flatten on selected cells, then reduce detail with Edit > Selection > Convert to polygons with a tolerance of 0.01 µm.
