This website serves as my blog where I post projects that I have worked on and how they have progressed.
I’ve been looking at voxel cone traced global illumination for a while as something that I want to implement since it gives a decent approximation of global illumination in real time for dynamic scenes. In the past month I’ve finally given myself a chance to look at the algorithm more in-depth and try at implementing it. Voxel Cone Traced Global …
I’ve been looking at a lot of resources on current rendering algorithms to get nice looking real-time graphics and thought that it’s time that I actually go and implement some of them. This is the first project that I worked on in a series of three that I used to improve my understanding of some graphics algorithms. I’m also using …
It’s been a while since I’ve done any updates, and I need to write some updates on specifics of stuff I’ve been doing. I put together a reel of some of my older projects along with some of my more recent projects that I have not had a chance to update about for a show my college was doing so …
I recently put together a demo for the art hop in Burlington. This demo renders 2.5 million particles and colors them based upon their velocity. This demo was written in C++ using Direct3D 11. The particles are simulated on a compute shader that I pass finger positions reported by the LEAP motion in world space. The LEAP is velcroed to …
I’ve been spending some of my free time researching and implementing rendering techniques (mostly researching as of this moment). I am currently focusing on developing a game engine and game that utilize the Oculus Rift and the Sixense STEM System. I have posted some videos of what I’m doing in my YouTube channel:
Originally I was computing the height of terrain per frame which was pretty wasteful since if I wanted more complex noise functions I would not be able to maintain a runnable frame rate. I moved the computation of terrain height to a compute shader which stores the height in a texture. I was also able to compute and store normals in …
In the week following my procedural terrain I added a dynamic quadtree-based LOD system in order to be capable of rendering large scale terrain at distances ranging from several kilometers to a few meters. At this point I ran into the issue that floating point is not accurate enough to accomplish centimeter precision at distances of several hundred thousand meters …
After doing atmospheric scattering I though that it would be an interesting challenge to make a full scale planet renderer. This is what I started with when looking to generate the terrain. The terrain height and color is determined through a height map that I generate in the vertex and fragment shaders. I generated the height map using the 2D …
A few months ago I decided to implement atmospheric scattering in my OpenGL renderer in order to create a day/night cycle. This turns out to be a fairly cheap effect to calculate if you do not need it to be completely accurate of implement multiscattering. One of the early GPU gems books had an implementation of atmospheric scattering that creates …
This application was made using XNA embedded in a Winforms project. The original tutorial for embedding XNA in Windows Forms can be found here. I needed to make some modifications to the ContentBuilder.cs included with the demo project to allow it to compile shaders and load fonts. I retrieved the map textures from the Google maps API. The height values …
