public class Viewport extends JPanel implements SceneChangeListener, MouseListener, MouseMotionListener, MouseWheelListener
Viewport is an JPanel that uses a set of RenderPasses to draw the Registry.getScene() from the perspective of the active Camera. Mouse actions in the panel can be used to manipulate the active camera.

    • getRayThroughPoint

      public Ray getRayThroughPoint(Camera camera, double normalizedX, double normalizedY)

      Return the ray, in world space, that starts at the camera and passes through this viewport at (x,y) in the current projection. x,y should be normalized screen coordinates adjusted for the vertical flip.

      Remember that in OpenGL the camera -Z=forward, +X=right, +Y=up

      Parameters:
      normalizedX - the cursor position in screen coordinates [-1,1]
      normalizedY - the cursor position in screen coordinates [-1,1]
      Returns:
      the ray coming through the viewport in the current projection.

    • getRayThroughPointUntransformed

      public Ray getRayThroughPointUntransformed(Camera camera, double normalizedX, double normalizedY)

      Return the ray, in camera space, that starts at the origin and passes through this viewport at (x,y) in the current projection. x,y should be normalized screen coordinates adjusted for the vertical flip.

      Remember that in OpenGL the camera -Z=forward, +X=right, +Y=up

      Parameters:
      normalizedX - the cursor position in screen coordinates [-1,1]
      normalizedY - the cursor position in screen coordinates [-1,1]
      Returns:
      the ray coming through the viewport in the current projection.

    • getCursorAsNormalized

      public javax.vecmath.Vector3d getCursorAsNormalized()
      In OpenGL camera space +Y is up and in screen space +Y is down so invert the Y value.
      Returns:
      the cursor position as (-1...1,-1...1,0).

    • getCursorAsNormalized

      public javax.vecmath.Vector3d getCursorAsNormalized(double x, double y)
      In OpenGL camera space +Y is up and in screen space +Y is down so invert the Y value.
      Returns:
      the cursor position as (-1...1,-1...1,0).
