Phase 5: Integration and Testing for 5D Noise #29

Task Description

Complete the integration of 5D noise implementation and create comprehensive tests.

Detailed Tasks

1. Update OpenSimplex2F.h

• Add noise5 function declarations
• Add orientation variant declarations
• Add helper function declarations
• Update context structure definition with permGrad5

2. Update OpenSimplex2F.c

• Implement full context initialization for 5D
• Add 5D noise function implementations
• Update OpenSimplex2F function to initialize 5D arrays
• Update OpenSimplex2F_free to clean up 5D resources
• Update OpenSimplex2F_shutdown to free 5D lattice points

3. Add 5D Noise to Context

• Initialize permGrad5 in OpenSimplex2F
• Allocate memory for 5D lookup tables
• Properly initialize all 5D arrays

4. Create Tests for 5D Noise

• Unit tests for 5D noise function
• Test boundary conditions
• Test coordinate transformations
• Test gradient selection
• Test vertex selection
• Compare with expected values

5. Update Documentation

• Add 5D noise usage examples
• Document coordinate system
• Add performance considerations
• Include benchmark comparisons

Files to Modify

• OpenSimplex2F.h - Update header declarations
• OpenSimplex2F.c - Update implementation
• tests/ - Add 5D noise test cases
• README.md - Update documentation

Notes

• Follow existing testing patterns
• Ensure backward compatibility with 2D, 3D, and 4D functions
• All functions should be properly exposed in the API

Acceptance Criteria

• All 5D functions compile and link correctly
• All tests pass successfully
• Documentation is complete and accurate
• No memory leaks detected
• Backward compatibility maintained]
