Highlighted outline is projected in wrong place

[mkarklins]

Describe the bug 📝

So, I added a highlighter with an outline on click. I would expect that the outline closely matches the BIM element, but the outline in some cases is way off the actual element.

This seems to be apparent only when you are streaming 2+ IFC files one on top of another. For a single streamed IFC file it seems to be working fine.

Steps to reproduce 🔢

Here's a react component I used to show the problem.

import { useEffect, useRef } from "react";
import Stats from "stats.js";
import * as OBC from "@thatopen/components";
import * as OBCF from "@thatopen/components-front";
import * as THREE from "three";

const BIMStreamingComponent = () => {
  const containerRef = useRef(null);

  useEffect(() => {
    const components = new OBC.Components();
    const worlds = components.get(OBC.Worlds);

    const world = worlds.create<
      OBC.SimpleScene,
      OBC.SimpleCamera,
      OBCF.PostproductionRenderer
    >();

    world.scene = new OBC.SimpleScene(components);
    if (containerRef.current)
      world.renderer = new OBCF.PostproductionRenderer(
        components,
        containerRef.current
      );

    world.camera = new OBC.SimpleCamera(components);

    components.init();

    if (world.renderer) world.renderer.postproduction.enabled = true;
    world.scene.setup();
    world.camera.controls.setLookAt(12, 6, 8, 0, 0, -10);

    const grids = components.get(OBC.Grids);
    grids.create(world);

    // Make the background of the scene transparent
    world.scene.three.background = null;

    const highlighter = new OBCF.Highlighter(components);
    highlighter.setup({ world });

    const outliner = components.get(OBCF.Outliner);
    outliner.world = world;
    outliner.enabled = true;

    outliner.create(
      "hightlightOutline",
      new THREE.MeshBasicMaterial({
        color: 0xbcf124,
        transparent: true,
        opacity: 0.5,
      })
    );

    highlighter.events.select.onHighlight.add((fragIdMap) => {
      outliner.clear("hightlightOutline");
      outliner.add("hightlightOutline", fragIdMap);
    });

    // Get the IFC streamer
    const loader = components.get(OBCF.IfcStreamer);
    loader.world = world;

    // Set the base URL for the streamer
    loader.url =
      "https://wbuploadsdev.blob.core.windows.net/wb-uploads-dev/38/";

    const uuids: string[] = [];

    // Function to stream the given model
    const loadModel = async (
      geometryURL: string,
      propertiesURL: string | undefined
    ) => {
      const rawGeometryData = await fetch(geometryURL);
      const geometryData = await rawGeometryData.json();
      let propertiesData;
      if (propertiesURL) {
        const rawPropertiesData = await fetch(propertiesURL);
        propertiesData = await rawPropertiesData.json();
      }
      const model = await loader.load(geometryData, true, propertiesData);
      console.log(model);

      model.items;

      uuids.push(model.uuid);
    };

    const models = [
      [
        "https://wbuploadsdev.blob.core.windows.net/wb-uploads-dev/38/fgpaj1-420pohistvoifc-geometries-streaming.json",
        "https://wbuploadsdev.blob.core.windows.net/wb-uploads-dev/38/fgpaj1-420pohistvoifc.ifc-processed-properties.json",
      ],

        "https://wbuploadsdev.blob.core.windows.net/wb-uploads-dev/38/fgpaj1-420gradbena-delaifc.ifc-processed-properties.json",
      ],
    ];

    models.forEach((model) => {
      // Start streaming the model
      loadModel(model[0], model[1]);
    });

    // Update the scene each time the user stops the camera
    world.camera.controls.addEventListener("sleep", () => {
      loader.culler.needsUpdate = true;
    });

    // Enable caching for the loader
    loader.useCache = true;

    // Customize the loader
    loader.culler.threshold = 0.00000001;
    loader.culler.maxHiddenTime = 100000000;
    loader.culler.maxLostTime = 300000000;
  }, []);

  return (
    <div
      id="container"
      ref={containerRef}
      style={{ width: "100%", height: "100vh" }}
    ></div>
  );
};

export default BIMStreamingComponent;

I found the same issue, also only when multiple IFC files are loaded.

[fethigurcan]

This issue is same for me, it happens when we use multiple models and it happens for non-first models. Hightlight is ok but Outliner draws at wrong place.

Should be solved from @thatopen/[email protected]!

Looks fine now, thank you!
