Class OctreeDemo

java.lang.Object
eu.svjatoslav.aukio.e3d.gui.humaninput.WorldNavigationUserInputTracker
eu.svjatoslav.aukio.e3d.examples.OctreeDemo
All Implemented Interfaces:
eu.svjatoslav.aukio.e3d.gui.FrameListener, eu.svjatoslav.aukio.e3d.gui.humaninput.KeyboardInputHandler
public class OctreeDemo extends eu.svjatoslav.aukio.e3d.gui.humaninput.WorldNavigationUserInputTracker
Demo showing volumetric octree rendering with raytracing capability. Creates a 3D scene with various geometric shapes stored in an octree data structure. Press 'r' to render the current view using software raytracing.

      public OctreeDemo()
      Creates a new OctreeDemo instance.

  • Method Details

    • main

      public static void main(String[] args)
      Entry point for the octree demo.
      Parameters:
      args - command line arguments (ignored)

    • buildScene

      public static void buildScene(eu.svjatoslav.aukio.e3d.renderer.raster.ShapeCollection shapes, eu.svjatoslav.aukio.e3d.renderer.raster.lighting.LightingManager lighting, eu.svjatoslav.aukio.e3d.geometry.Camera camera)
      Builds the demo scene: grid, light sources, and the full initial voxel bake (spiral, arbitrary rectangles, tiled floor, fractal) added both to the raster scene and to the octree volume, exactly as shown on startup. Called by both main(String[]) and the golden-image harness — must stay deterministic (no time, no unseeded randomness).
      Parameters:
      shapes - scene to add shapes to
      lighting - lighting to configure
      camera - camera to position

    • keyPressed

      public boolean keyPressed(KeyEvent event, eu.svjatoslav.aukio.e3d.gui.ViewPanel viewPanel)
      Handles keyboard input for triggering raytracing.
      Specified by:
      keyPressed in interface eu.svjatoslav.aukio.e3d.gui.humaninput.KeyboardInputHandler
      Overrides:
      keyPressed in class eu.svjatoslav.aukio.e3d.gui.humaninput.WorldNavigationUserInputTracker
      Parameters:
      event - the key event
      viewPanel - the view panel
      Returns:
      true if the event was consumed
