v1.0.0

DNA Visualizer v1.0.0 — Initial Release

First public release of DNA Visualizer — an interactive 3D double-helix viewer built with C++ and OpenGL

Features

• Procedural DNA double helix: nucleotide spheres, backbone tubes, and base-pair bridges.
• Per-base coloring (A / T / G / C) with Watson–Crick complementary strand B.
• Arcball camera with mouse orbit and scroll zoom.
• MutationEngine — point substitutions with on-screen highlight and mutation history log.
• Helix regeneration with adjustable length (8–64 bp).
• Phong shading with diffuse texture, ground plane, and pedestal.
• Off-screen rendering via framebuffer (color + depth).
• Post-processing stack: Sobel edge detection, FXAA, and vignette.
• Dear ImGui panels: DNA Sequence, Render Settings, Controls & Stats.
• Keyboard controls for helix rotation, scaling, animation toggle, and camera reset.

Architecture

• Modular codebase split into core, dna, renderer, and ui.
• Real-time FPS and frame time display in the UI.
• Adjustable Phong lighting (ambient, diffuse, specular, shininess).
• Toggleable helix spin animation with configurable speed.
