Acceleration Structures and Grids Interested of ways that have fewer number of rays per intersection Acceleration structures: Acceleration and Regular Grids Bounding Volume Hierarchies Bounding Box Test Hierarchical Bounding Box Test Binary Space Partitioning (BSP) Trees BSP trees
camera ray casting from this get the ray : Shading Model Recursive Ray Tracing For each pixel trace primary ray, find intersection trace secondary shadow ray to all lights – color = visible ? illmodel : 0 trace reflected ray – color += reflectivity * color of reflected ray (recursion)

Raytracing 1: Intersections different type of rays need different information, shadow rays intersection / no intersection. primary rays: point of intersection materials, normal, text coord .. etc Ray-Sphere Intersection Substitute: Simplify Substitute: quadratic equation for t Intersection point substitute t back to the ray equation. surface normal at point of intersection: Ray-Triangle Intersection Combine with…
Notes and learning diary for CSE168 rendering course on Edx that is part to of CSE167 Computer Graphics course on Edx by Ravi Ramamoorthi.https://learning.edx.org/course/course-v1:UCSanDiegoX+CSE168X+3T2024/ Course projects / homeworks: Systems write modern 3d image synthesis program.(path tracer with importance sampling) RAYTRACING 1: RAY CASTING Effects needed for realism raytracing: pixel by pixel instead of object by…
I have been working on my own toy renderer projects to learn graphics programming and for basis of small rendering / game engine when I have time for it. First project I made implemented deferred rendering, basic lights and shadows, obj loading and gui rendering with help of some 3rd party libraries (tinyObj and Imgui)…
I finished reading the third book of the ray tracing mini books by Peter Shirley and wanted to post some renders of the books.Last book introduced monte carlo method and more complete ray tracer. I have also bought the book Physically Based Rendering 3rd edition that I am really looking forward to dive into and…
Short list of helpful pages about making a 64k demoscene intro.
Last week I finally finished the UE4 C++ course in Udemy by Gamedev.tv! It was suprisingly long course that covered a lot of material in both C++ and blueprints in the UE4 engine. There was alltogether 55.5 hours of lectures but I think since I did all the projects and challenges it took my at…
