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 recently finished an Edx MOOC course Computer Graphics (cse167x by UC San DiegoX ) taught by professor Ravi Ramamoorthi. I also achieved a verified certificate from the course. The course taught the foundations of computer graphics by using OpenGL in homework projects as well as asking the student to implement basic ray tracer from…
