1. Introduction

This is my exercise on ray tracing, based on

• Ray Tracing in One Weekend (completed)
• Ray Tracing the Next Week (currently working upon)
• Ray Tracing the Rest of Your Life (upcoming)
• Real-Time Rendering (forth Edition) (upcoming)

Along with changes, optimizations, and additions to the content For details, please refer to the notes and source code The graphics interface uses OpenGL 4.4

Recently working on > Ray Tracing the Next Week

2. Code Framework (will be updated)

Inside ./Raytracing-Sandbox/Src/

Compute-Shader/
   00_Basic_Compute_Shader
   01_Blur_Using_Compute_Shader
   02_Evolving_Pics (Partially-finished due to unforseen circumstances (ristricted and small gpu stack))

In-One-Weekend/
   00_Image
   01_Adding_Sphere
   02_Grouping_Objects(Scene)
   03_Adding_Materials

In-Next-Week/
	00_MotionBlur
	01_BoundingVolumeHierarchy (LBVH to be exact(not GPU but CPU based), NOTE: reflections are not good due to motion blurring not beacause of bug, I always confuse In spelling of heirarchy, code needs very-good amount of cleanup)
  // SWITCHING PRIORITIES, NOW GOAL IS TO FINISH THIS AS SOON AS POSSIBLE INSTEAD OF MAKINg IT LOOK GOOD (17.08.2021) {also the reason why i'm not switching to SSBO instead of texture for buffer}. 
    03_Texturing ([⩗]texture loading from disk, [⩗]noise texture, [⩗]mercator texture <-> cubic texture).
	NOTE: (well its okay for naming to be like this as BVH took quite a big toll on me)Inconsistency in GeometryData.size() and num of geometries to render so i'm just gonna disable from Gui (a.k.a NumberOfGeometriesToRender)
    04_Lighting (Logic Implimented, though few artifact here and there are showing up).

2. How to use

2.1 Dependencies
