    • extractScale

      public static float extractScale(org.joml.Matrix4f matrix)
      Extracts the greatest scale factor across all axes from the given matrix.
      Parameters:
      matrix - The matrix to extract the scale from.
      Returns:
      The greatest scale factor across all axes.

    • writePackedFrustumPlanes

      public static void writePackedFrustumPlanes(long ptr, org.joml.Matrix4f m)
      Writes the frustum planes of the given projection matrix to the given buffer.

      Uses a different format that is friendly towards an optimized instruction-parallel implementation of sphere-frustum intersection.

      The format is as follows:

      vec4(nxX, pxX, nyX, pyX)
      vec4(nxY, pxY, nyY, pyY)
      vec4(nxZ, pxZ, nyZ, pyZ)
      vec4(nxW, pxW, nyW, pyW)
      vec2(nzX, pzX)
      vec2(nzY, pzY)
      vec2(nzZ, pzZ)
      vec2(nzW, pzW)

      Writes 96 bytes to the buffer.

      Parameters:
      ptr - The buffer to write the planes to.
      m - The projection matrix to compute the frustum planes for.
