Books
Writing great games isn't just about luck or magic - it isn't just about great graphics or storyline - writing a great game is an art! Learn about why so many games end up in the game graveyard. Do you feel like cookin up some WebGPU code dishes? If Yes! Give this text a go! Jam packed full of examples on a whole range of topics - both as a springboard for learning and as a reference text for those 'how-to'! times. Colorful beginners guide to getting started with the WebGPU API and WGSL language.

Little Black Book of Ray-Tracing and Path Tracing

The future of computer graphics.....

  



Little Black Book of Ray-Tracing and Path-Tracing




Available Amazon



The little black book is both a learning resource and a reference text that provides lots of insigheds and hands-on examples to teach and inspire you! If you're looking to get started - or want to try out something new - this text is definetly for you!

• Key ray/path tracing information
• Develop parallel ray/path-tracing solutions with GLSL (WebGL)
• Lots of hands-on examples (with code) from very basic through to more complex/advanced concepts
• Great resource for building up your portfolio
• Quick reference text (how-to) for times when you've forgotten or need to know how to do something
• ..


Book Example Projects - Starts with Hello WebGL and GLSL Shaders


The examples are grouped into different areas - with links proving a link to the WebGL Lab - so you can tinker with an onlin interactive.



Full Screen Quad


A basic full screen quad - an empty WebGL/GLSL code - full screen quad vertices are created on the vertex shader and the fragment shader interpolates the texture coordinates across the screen (visualized as color).



GLSL 2D Circle


Take things a bit further - and use the texture coordinates to draw a circle in the fragment shader (simple bounding distance check).




Essential Intersection Algorithms


Simple ray-sphere intersection on the GLSL fragment shader - no lighting or frills - just a basic ray-tracer starting point (also the setup code for WebGL).



Ray-Plane Intersection


Ray-tracer intersection test with a ray and plane.



Ray-Rectangle-Plane Intersection


Ray rectangle plane intersection - extends the ray-plane but adds a boundary.



Ray-Intersection (Sphere and Plane) - Multiple Geometry (Depth)


Ray-tracing intersection test for both ray sphere and plane.



Ray-Triangle Intersection


Ray-Triangle Intersection Test.



Classical Ray-Tracing: Minimal Working Example


Classic Ray-Tracer (Ray-Sphere)


Ray-trace a basic sphere.



Ray-Tracer Camera


Ray-Tracer Camera - with Ray-Sphere Test Case.



Classic Ray-Tracer (Reflections)


Classical Ray-Tracer - with Reflection Test (Mirror)



Classic Ray-Tracer (Refractions)


Classical Ray-Tracer with Refraction Test (Glasss)



Phong Lighting


Classic Ray-Tracer with Phong Lighting - Diffuse Test Lighting Test.



Direct Lighting - Hard Shadows


Ray-Tracing Direction Light - Hard Shadows Example (Single Direct Ray)



Direct Lighting - Soft Shadows


Ray-Tracing with Direct-Light - Soft Shadows (using multiple rays).



Refraction & Reflections (metal and glass)


Reflections and Refractions


Ray-Tracing Reflection and Refraction Example.



Fresnel Effect


Ray-Tracing Fresnel Test.



Distributed (Multiple Primary Rays)


Distributed Ray-Tracer


Distributed Ray-Tracing - Primary Rays Only



Distributed Ra-Tracer (Multiple Primary Rays) - Soft Shadows


Distributed Ray-Tracing - Soft Shadows (Primary Rays Only)



Path-Tracing


Ray-Tracer - Feedback Loop


Ray-Tracer - with Feedback Loop (Last Frame Passed onto Next Frame As Image/Texture)



Path-Tracer - Simple Sphere


Path-Tracer - Simple Sphere Example.



Path-Tracer - Materials


Path-Tracer Material (Matt and Gloss)



Path-Tracer - Roughness


Path-Tracer Roughness Test Example.



Scene/Data Management


Triangle Rabbit Mesh (Matt)


Ray-Tracing Rabbit using Triangles (loaded from file)



Triangle Rabbit Mesh (Mirror)


Ray-Trace Triangle Rabbit (using Mirror Material)



Triangle Rabbit Mesh (Texture Buffer for Mesh Data)


Ray-Tracer (Path-Tracer) for the Triangle-Bunny - Triangle mesh is stored in a texture buffer instead of a uniform buffer.



Octree Structure for Triangles


Ray-Tracer (Path-Tracer) - for the triangle mesh (bunny)- but the data is organised as an octree structure.



Octree Structure (Debug Wireframe) for Triangles


Ray-Tracer (Path-Tracer) using Octree for the Ray-Triangle Collisions Detection - Added 'Wireframe' Box (Draw Octree Data)
