Greptile Overview

Greptile Summary

This PR applies miscellaneous type and comment improvements to camera-related code across 10 files with no functional changes.

Key changes:

• Replaced Matrix3D(1) with Matrix3D(true) across all files to use explicit bool parameter instead of implicit int-to-bool conversion, improving code clarity
• Fixed float literal precision in camera.cpp files by changing tan(x/2.0) to tan(x/2.0f) to avoid unnecessary double precision calculations
• Corrected documentation typo in Un_Project comment: changed "ViewPlaneMin.X" to "ViewPlaneMin.Y" for the Y-axis mapping
• Added detailed inline comments in frustum.h documenting the Planes and Corners array indices
• Removed extraneous blank line in Set_View_Plane function

All changes are cosmetic refactorings that improve code quality, readability, and type safety without altering runtime behavior.

Confidence Score: 5/5

• This PR is safe to merge with no risk
• All changes are cosmetic refactorings that improve code clarity without affecting functionality - explicit type conversions, corrected documentation, and added helpful comments
• No files require special attention

    Dev->>Code: Identify Matrix3D(1) calls
    Note over Code: Multiple files use implicit<br/>int-to-bool conversion
    
    Dev->>Code: Change Matrix3D(1) to Matrix3D(true)
    Note over Matrix: Explicit bool parameter<br/>makes intent clear
