+# Educational Notes:
+# Scene Design Philosophy:
+# - 11 spheres total for complex intersection testing
+# - Varied radii (0.4 to 1.0) to test algorithm robustness
+# - Strategic Z-depth distribution (-4.0 to -8.0) for depth complexity
+# - Asymmetric positioning to avoid mathematical edge cases
+# - Color variety demonstrates material system capabilities
+# - Sphere count optimized for <1 minute render at 1024x768
+
+# Performance Characteristics:
+# - Intersection tests per ray: ~11 (one per sphere)
+# - Expected hit rate: ~15-25% (realistic for scene density)
+# - Memory usage: Scene data ~2KB + image buffer based on resolution
+# - Ray count at 1024x768: 786,432 total rays
+# - Estimated render time: 30-45 seconds on modern hardware
+
+# Visual Composition:
+# - Front row provides immediate visual interest
+# - Middle row adds depth and complexity
+# - Back row creates atmospheric perspective
+# - Color progression from warm (front) to cool (back) adds depth
+# - Size variation creates natural focal hierarchy
