The browser keeps named objects in a scene graph. The command text is the authoritative representation; Rebuild / Run All clears generated nodes and reconstructs them. Inspector changes are written back into the command text.

Use Choose CSV Frames to register all timestep files. A command such as WEBVOXELSEQUENCE delta "delta_frame*.csv" THRESHOLD 0.05 MAXCUBES 3000 FPS 3 LOOP ON CUBESIZE AUTO matches those registered filenames, naturally sorts them by their numbers, and displays each frame as one GPU-instanced cube mesh. The CSV header must be x,y,z,vox. Positive values are orange/red and negative values are blue/cyan. The timeline controls appear automatically.
The browser scans a frame and retains the largest-magnitude values that pass the threshold, up to MAXCUBES. This avoids creating thousands of independent scene-graph nodes and is substantially faster than one WEBBOX per voxel.
Click visible geometry in the 3D viewport to select it. A transform gizmo appears at the active transform node. Use Move, Rotate, or Scale in the toolbar, or keyboard shortcuts W, E, and R. Press Q for world/local coordinates and Esc to deselect. Enable Snap for 0.25-unit translation, 15-degree rotation, and 0.1 scale increments.
During a gizmo drag, the selected node's DCS command is continuously rewritten in the editor. If clicked geometry has no transform node, v4 creates a name_xform DCS wrapper and updates the relevant ADDCHILD relationships before manipulation begins.
Use the Stereo: OFF/ON button in the top toolbar. Stereo mode divides the browser canvas into left-eye and right-eye views suitable for side-by-side (SBS) 3D displays. The eye-separation slider changes the stereo baseline; 0.065 is the default. Stereo changes only how the scene is viewed and does not alter the IRIS model or command text.
IRIS normally loads OpenSceneGraph-supported model files. A browser cannot directly interpret native OSG/IVE files, so this version accepts browser-friendly GLB/GLTF, OBJ, and STL. For an OSG/IVE workflow, convert the geometry to GLB/GLTF while preserving node names where possible, then keep the IRIS control file for scene-graph transforms and attachment commands.
Commands that depend on a native IRIS process, DSOs, FIFOs, shared memory, shell execution, or operating-system process control are intentionally not executed in the browser.
