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…
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…
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…
Rendered two videos after finishing first section Epic approved UE4 course of https://www.udemy.com/unreale4 First video is room I quickly put together by myself second one is after followed the course videos. Video of cinematic sequence of my room: Sequence of room made following the course videos:
Finished reading excellent ray tracing books by Peter Shirley: Ray Tracing in One Weekend (Ray Tracing Minibooks Book 1) and Ray Tracing: the Next Week (Ray Tracing Minibooks Book 2) I also finished coding the example ray tracing project from the books. There is also third book in the series that I have bought for kindle and hope to…
Finally had time to finish to finish section 4 of the Unreal Engine 4 C++ course in Udemy the BattleTank game. This section taught a lot C++ programming in UE4, some UI, landscape creation, game pad inputs and input events and very simple AI for enemy tanks. Short gameplay video I made of the project…
