RayTracer for iOS! [4th version: Multi-thread + iPad]
A new version of my RayTracer is available for iOS! Now it has a multi-threaded renderer (it might run faster on your device), and iPad is now supported.
Download
It is also possible to create images with a user-defined dimension (bigger or smaller than the screen).

RayTracer for iOS! [new version!]

RayTracer for iOS!
After one night of work (from 11 pm to 4 am), I finally ported my RayTracer to iOS! This version of my RayTracer is still very incomplete and there's still a lot of work to do (mainly in the user interface), but I am still learning how to program in Objective-C (I only watched 4 classes of that online iOS course from Stanford University), so I think porting this program is a good start for me!

Update
iPad version coming soon! There are some performance issues to be dealt with before I can release this version...

Some of my work for University - Part 1
As I approach the end of my Computer Science course, I will post some of the work I did for university. Feel free to reuse some of my code (for academic purposes ONLY!), but remember to give me credit for it (citing my name and a reference to this blog would be nice :-) ).
Ceres Shell (University of São Paulo - Operating Systems II - 2011)
Description: Simple shell program similar to sh, with Ceres programming language as its script language.
OS: Linux, and OS X.
Requires: -
Language: Portuguese
RollerCoaster (Dalhousie University - Computer Animation - 2012)
Description: Roller coaster simulator programmed in C with OpenGL (uses Uniform B-Spline curves for the roller coaster generation).
OS: Linux, and OS X.
Requires: GLUT (OpenGL)
Language: English
Physics (Physically based animation) (Dalhousie University - Advanced Computer Animation - 2013)
Description: Physically based animation programmed in C with OpenGL (using quaternions, laws of motion, and numerical integration).
OS: Linux, and OS X.
Requires: GLUT (OpenGL), LAPACK, and BLAS.
Language: English
I will post more soon, I hope you like it!
P.S.: I moved back to Brazil after 8 months living in Canada!

Updates!
Wow, It has been a while since the last time I posted something here... Well, I need to update this blog! I am now living in Halifax, NS, Canada and I am a visiting student at Dalhousie University (as part of the Science Without Borders programme of the Brazilian Government). I am still programming some nice stuff, I hope I can show you something new soon!
See ya!
See ya!

CG related projects!
As promised, I'll show you some of my undergraduate projects. I'm beginning with computer graphics related projects and I plan to show you some other projects in latter posts.
NeoCore
As I said before, after the first semester of my undergraduate course I wrote a ray-caster. NeoCore is the result of this work. It's a simple first person shooter game engine, written in C (and not optimized) using Allegro, capable of rendering a maze-like scene with some interactive objects (like the lava, which causes you damage if you step into it, and a bot, which has random movements). This is one of my last programs written for Windows (although It wouldn't be hard to port it to Linux as I didn't use any Windows API calls explicitly).
An early version of NeoCore (v.0.0.4).
NeoCore version 0.0.9.
You can download NeoCore from SourceForge. Before you download, I warn you that the code that I wrote for this project (although it's much better than the one I wrote for "the Core") is of bad quality!
O vôo da Discovey (The Flight of Discovey)
This project was EPIC! Simply no words to describe it... We (Gustavo Buzogany, Leticia Rostirola and I) created a 3D scene showing Discovery's last return to Earth from the International Space Station. This project was meant for our Computer Graphics discipline. In this discipline we had to create an animated 3D scene (using OpenGL for graphics). So we wrote a C++ program (using OpenGL and SDL) that could read OBJ models (we borrowed some code for OBJ parsing and bitmap loading) and render them in the scene, this program also used some shaders (GLSL) for atmospheric scattering of light (used on Earth's atmosphere) and for day/night/cloud textures on Earth. The user could interact with this program (for camera control) using the computer keyboard or trough the 4th generation iPod Touch gyroscope (as shown in the following video).
The "trailer" for our presentation, showing some parts of the 3D scene (Portuguese version).
Same as above (English version).
Open Core Raytracer
After finishing my Computer Graphics discipline I started this project. This is a ray tracing program based on my CG teacher's Raytracer. It is very similar to his Raytracer, although mine is written in C++ (his is written in Java) and has a few more features (like parsing a file describing the scene to be rendered). This Raytracer is still very simple, it lacks some basic features like texture mapping and 3D model rendering. You can also download it from SourceForge. These are some images rendered with this Raytracer.
Some reflections...
And this is the "scene description file" for the image above...
scene {
antialiasing;
save("scene3.bmp");
dimension {
width = 400;
height = 400;
}
background {
color = (40, 40, 40);
}
camera {
viewup = (0, 1, 0);
lookat = (0, 5, 0);
eye = (-5, 8, 5);
fov = 45;
zvp = 0.1;
}
light {
ambient = (255, 255, 255);
diffuse = (255, 255, 255);
specular = (255, 255, 255);
position = (2, 11, 6);
}
sphere {
position = (0, 5, 0);
radius = 1;
material {
ns = 300;
transp = 0;
reflt = 0.15;
ambient = (0.1, 0.1, 0.1);
diffuse = (0.8, 0.8, 0.08);
specular = (0.98, 0.98, 0.8);
}
}
box {
position = (0, 4, 0);
size = (3, 0.5, 3);
material {
ns = 300;
transp = 0;
reflt = 0.75;
ambient = (0.1, 0.1, 0.1);
diffuse = (0.5, 0.5, 0.5);
specular = (0.8, 0.8, 0.8);
}
}
}
That's all for now gentlemen! See ya!
