    • splitByVisibility

      protected void splitByVisibility(Vector4 forward)
      Check if the face is visible or not. Due to the convex solid property, a positive dot product means that the face has the normal in the same direction of the sight, thus it is not visible because there exist faces which cover the sight of the analyzed one.
      Parameters:
      forward - Viewing direction.

      Formats a floating point value with the specified number of decimals.
      Parameters:

      protected int printMatrix4(Graphics2D g, Matrix4 m, int x, int y, String name)
      Prints matrix coefficients in a human-readable manner.
      Parameters:
      g - Graphics context.
      m - Matrix to print.
      x - Left coordinate.
      y - Top coordinate.
