Projects tagged ‘raytracing’

just some implementations of common realtime and raytracing algorithms, as my own personal pet project aside from my job as game programmer. feel free to steal my shit, just quote me accordingly. ... [More] this will all be heavily commented and absolutely "hands on". I try to do as much as possible by hand, since it is also intented as a notebook of sorts for me to remember things. I have a bad memory for stuff like "how could I get mSec time out of windows again?!" and other details that I keep forgetting. so... have phun. UPDATE: I guess it's better to start out with raytracing only. so mostly no OpenGL-stuff for now. -marcus [Less]

This is a learning project, mainly for me, to learn about raytracing and illumination. My main knowledge source right now is "Physically Based Rendering" as well as ompf. Puma is developed on Linux ... [More] AMD64, but should work on x86 and Windows as well. The main goal of this project is to develop a raytracer, capable of executing different Global Illumination algorithms. News 09.09.2009 Added gamma correct rendering. Final images are encoded into sRGB. This gives some really nice, bright images (now I know why my images were so dark...). However, this change cost quite a lot in terms of runtime performance (around 100ms per frame), so I finally started using SSE. Some SSE code is used now for converting the float-colours into uint8-colours including srgb conversion and clamping. This brings the time per frame back to its previous range :-) Now I need to find out why TBB eats 25% of each frame's time :-( 05.09.2009 Replaced all internal acceleration structures by TinyRT. However, barycentric coordinates for interpolating data inside a triangle is broken with this change. Speed is way better than previously. So I will fix this now... Barycentric coordinates work now. The indices have to be in a special order for TinyRT to work correctly. Updated the statistics below. Current Features: loads Quake3 maps and Wavefront obj files basic texture support very basic lighting and textures, no shadows using Configurable Math Library for math FPS-style camera Next on list: add some lighting support Requires: SDL for window creation and event handling scons for building Intel TBB Optional: google perftools for faster allocating and profiling The following screenshots show the Aria Decapo Quake 3 Map. Statistics for 1280x800 (images are 640x480), same position as first image: 1280x800 one ray per pixel rendered at ~5 FPS on a Intel Q9300, 180-200ms per frame Lighting via lightmaps with bilinear filter [Less]

Ratracer running entirely on gpu, using CUDA library

System of rendering based on voxels and ray tracing.

Advanced Image Synthetizing module project IFIPS 2007-2008 Teacher : Samuel Boivin Author : Camille Maurice

The example renders a simple scene, which consists of a procedure landscape and two spheres with arrow manipulators ( they allow to move spheres ). The core algorithm computes a visibility of an one ... [More] sphere from the other center. RayComputer uses a GPU raytracing to solve the task, and OclQueryComputer uses a hardware occlusion query. Also introduce a simpe scene graph api ( RenderObject ). [Less]

Dwen is a raytracer written by myself as a set of educational exercises. It is free for others to modify, redistribute, etc, and the writer encourages it to be used for learning purposes. Dwen is ... [More] written to be as modular as possible, so that core features may be modified/augmented or new features might be added. Dwen was written in the hope that, after the core product was written, time was spent writing features instead of restricting, unnecessary code. -Duane R. Bailey [Less]

My thesis assignment is the development of educational software for Computer Graphics courses. I decided to make an application that is capable of visualizing ray tracing algorithms.

I am learnig how to build a graphics engine by hand and wish to learn ray tracying

The simple raytracing program. Please view wiki.
