25d View | Klayout

The 2.5D View 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

Future Directions: From 25D to True 3D in KLayout

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. klayout 25d view

• Assign height to structural polysilicon and sacrificial layers.
• Tilt the view to inspect undercut clearance.
• Spot potential stiction zones where tall structures bend too close to the substrate.

# Example KLayout Ruby script to export a 25D view as PNG
view = RBA::Application::instance.main_window.current_view
view.set_config("use-2.5d", "true")
# Set layer heights programmatically
layer_index = view.layer_index_for(LayoutView::Layer.new(1, 0))
view.set_layer_property(layer_index, "2d-height", 0.5)
# Capture image
image = RBA::Image::new(view.max_viewport_width, view.max_viewport_height)
view.render_image(image)
image.save("layout_25d_snapshot.png")
