Instance Cloud Reduction reloaded
Jun 30th
OpenGL 3.3 - Nature
A few months ago I’ve presented an object culling mechanism that I’ve named Instance Cloud Reduction (ICR) in the article Instance culling using geometry shaders. The technique targets the first generation of OpenGL 3 capable cards and takes advantage of geometry shaders’ capability to reduce the emitted geometry amount in order to get to a fully GPU accelerated algorithm that performs view frustum culling on instanced geometry without the need of OpenCL or any other GPU compute API. After the culling step the reduced set of instance data is fed to the drawing pass in the form of a texture buffers. In this article I will present an improved version of the algorithm that exploits the use of instanced arrays introduced lately in OpenGL 3.3 to further optimize it.
RasterGrid Blog crossed the 10000 threshold
Mar 9th
I am proud to announce that the number of visits has just gone over 10000. I would like to share that I haven’t expected such a great success in less than two months. I can hardly thank this enough to all my occasional and especially for my returning visitors!
When I’ve started to write this blog my primary intension was to share my knowledge and ideas, no matter if they are legitimate enough or not. I did this in the hope that the articles on this blog may help others. At the end, it turned out that me myself learned from it a lot as, thanks to You, I’ve got great improvement ideas and feedback about my writings.
Site successfully migrated
Jan 28th
Almost a week ago I was talking about the problems with the server on which my blog is stored and I promised that it will be put to another server at least on Tuesday in order to not have any troubles with the reachability of the site. Unfortunately, due to environment problems this actually happened only during last night. Anyway, I am happy that the migration is over now and I hope it won’t happen again.
Problems with the availability of the site
Jan 23rd
I started my blog about two weeks ago but already met some problems regarding to the availability of the site. It happened a few times that there was some problem with the Apache Server at the hosting company. This resulted in some short down times of the blog itself. I was saying that “okay, this is not that big problem” so I accepted the barely limited up-time of the server. But today something much worse happened. The server was down for hours, I don’t even know for how much time so I decided to make some action to prevent such problems in the future.
