4. Image Generation Algorithm ä For each row: ä For each data point in the row (start from left): ä Determine which pixel left eye sees. ä Determine which pixel right eye sees. ä For each pixel in the row (start from left): ä If pixel not already colored, color randomly. ä Color corresponding right eye pixel the same.

5. The Mathematical Model What did the eyes see? And where did they see it? Surface being viewed (Data Field) Far Plane - furthest away any point can be. Horizontal Reference Line - i.e., x = 0 Point of Interest Eye Level Left Eye Sight Line Right Eye Sight Line Left Eye x1x1x1x1 z Image Plane Left Eye’s Pixel Right Eye’s Pixel D2D2D2D2 D1D1D1D1 XLXLXLXLs l_pix r_pix BY SIMILAR TRIANGLES

6. Next Focus is to integrate SIRDS algorithm into existing skeleton program.
