RM Coloring / Proxy to RM Projection (Experimental)

Warning

This panel is experimental. Behavior, operator IDs and property names may change between releases. The page is built but kept out of the main navigation until the feature stabilizes.

To make this panel visible in Blender, enable scene.em_tools.experimental_features and ensure RM temporal sync is active.

Overview

RM Coloring renders Representation Model surfaces using the colors of the proxies that intersect them, so that a viewer can visually assess which stratigraphic unit occupies which portion of the RM.

The feature has two UI surfaces, both gated behind experimental features:

  • A collapsible section inside Visual Manager labelled RM Coloring (Experimental), drawn inline by visual_manager.ui.VisualManager.draw_rm_coloring. This is the recommended entry point for users.

  • A standalone sub-panel VIEW3D_PT_proxy_projection_panel labelled Proxy to RM Projection (Experimental), registered as a child of Visual Manager, kept mainly for deep links and scripting.

Methods

Two projection methods are provided via the scene.proxy_projection_settings.method enum:

  • Vertex Paint — bakes proxy colors into the RM’s vertex color layer. Fast, non-destructive; the RM’s material is not modified.

  • Material Override — inserts a mix shader node network into the RM’s material (named RMColoring_Multi_*) blending proxy color with the original texture. See proxy_to_rm_projection/material_override.py.

Controls

When inactive, the section shows an Apply RM Coloring button (guarded by prerequisite checks). When active:

  • Clear Coloring — remove the coloring artefacts.

  • Update — recompute intersections / shader setup.

  • Toggle — temporarily hide/show the coloring without removing it.

  • Auto Update — rebuild on depsgraph changes.

  • Blend Strength — mix weight between proxy color and the original material.

  • Hide Non-Intersected Areas — mask parts of the RM that no proxy touches.

Operators

All live in proxy_to_rm_projection/operators.py:

  • proxy_projection.apply

  • proxy_projection.clear

  • proxy_projection.update

  • proxy_projection.toggle

  • proxy_projection.update_strength

  • proxy_projection.update_visibility

  • proxy_projection.update_colors

  • proxy_projection.diagnose — emits a diagnostic report to the console.
