CSC 240: Final Quiz Grading Rubric Part 1: (25pts) (a) 15 - correct viewpoint, labels, axis, frustum; correct similar triangles math and result 13 - small math error or correct work but wrong conclusion 10 - correct analysis of y-coordinate of P but no analysis of x, or some mix up of x and y 4 - some diagram and start of a correct solution (b) 10 - correct coordinates and drawing for both cases 6 - only perspective correct or significant progress on both cases 4 - only orthographic correct or some progress on both cases Part 2: (20pts) (a) 10 - color correct for all points 8 - minor error (some points incorrect or colors “flipped”) 5 - major error (several points incorrect or inconsistent) (b) 10 - all points labeled correctly and “perpendicular point” (P4) shown clearly 8 - minor error (one point mislabeled or some points shifted 5 - major error (labels of points “flipped” or inconsistent) Part 3: (20pts) (a) 5 - tree completely correct and labeled with push/pop 3 - minor conceptual error in tree structure 1 - progress toward a correct solution (b) 5 - all objects have correct transformations and order 3 - minor conceptual error (either more or less transformations) 1 - progress toward a correct solution (c) 5 - all objects with correct shape, location, and orientation 3 - minor error in either location, shape, or orientation 1 - a diagram on the right track (d) 5 - motion of all objects correctly described, and their relationships 3 - minor error (typically that 1/2 were rotating around 3, but little description of how 1/2 were moving relative to each other) 1 - some description of correct motion Part 4: (10pts) 10 - correct analysis of the problem and description of how to fix it 8 - correct analysis of the problem but orientation error in the fix 2 - identified an incorrect issue Part 5: (25pts) (a) 5 - correct camera location (with work) 3 - minor conceptual error in how to get the camera location, but close 1 - some progress toward a correct solution (b) 10 - correct t and P (with work), or correct based on an incorrect camera position 8 - minor conceptual error in work, but right idea of how to get t and P 5 - either P or t correct 2 - progress toward a correct solution (c) 5 - correct reasoning and result (does not intersect mirror) 3 - minor conceptual error in either reasoning or result 1 - progress toward a correct solution (d) 5 - both a description of how to get P and a correct inequality for inside/outside 3 - minor conceptual error or partially incomplete solution 1 - some correct reasoning or steps of the algorithm
