784 // Add my own version of gluLookAt() (which is nearly identical to the
785 // Mesa/glu version.) But, by calculating the Model View matrix our selves
786 // we can save this matrix without having to read it back in from the video
787 // card. This hopefully allows us to save a few cpu cycles when rendering
788 // out the fragments because we can just use glLoadMatrixd() with the
789 // precalculated matrix for each tile rather than doing a push(), translate(),
790 // pop() for every fragment.

811 // Shuffled some additional view parameters into the fgVIEW class.
812 // Changed tile-radius to tile-diameter because it is a much better
814 // Added a WORLD_TO_EYE transformation to views.cxx. This allows us
815 // to transform world space to eye space for view frustum culling.
