Project Value Noise

Project Overview

This project focused on implementing a procedural Value Noise generator in C++ using modular helper components for smoothing and interpolation.

Tasks Completed

• Implemented Fade.hpp to define various smoothing methods including Linear, Cosine, Smoothstep, and Quintic.
• Created Interpolation.hpp containing reusable templates for linear, bilinear, and trilinear interpolation.
• Developed NoiseCoordinate.hpp to convert floating-point inputs into discrete cell coordinates and interpolation weights.
• Built ValueNoise.hpp to evaluate 1D, 2D, and 3D Value Noise using the above modules, fully templated and period-adjustable.

Reflection

One of the most challenging aspects was understanding the difference between layout(location = 0/1/2) in shaders, and ensuring vertex attributes matched correctly. Additionally, I learned that fragment output must be explicitly defined using layout(location = 0) out vec4 fFragmentColor, and not just assigned to a variable like fragColor. This debugging process improved my understanding of the GLSL pipeline and the tight coupling between vertex input and fragment output stages.
