Sometime ago I saw a TedTalk done by Mr. Daniel Wolpert, which now (once I’ve watched it again) made an even deeper impression on me; The bayesian predictions and the feedback loops are surely something worth thinking about, but the first time I’ve watched it I’ve became instantly occupied with one of the very first sentences he said, paraphrasing: “The […]

The 3rd semester of Computer Science on Wroclaw University of Technology brought to me an occasion to do something that was written for a long time in my Idealist. After writing a 3d engine with Gouraud shading and per vertex Phong lightning model, which was the basis of evaluation of the graphics course, I’ve decided to do something […]

Today I announce the first alpha version of External Lightmapping Tool that works not only with 3dsmax and Windows, but now also with Maya and Mac OSX. So far the system was tested on Windows 7 and Mac OSX Snow Leopard with Maya 2010. The package can be downloaded from here: http://unitylightmapper.googlecode.com/files/elt_maya.zip How to use […]

It’s been a while since the first post about the lightmapping tool (even the name evolved to a more general one ) and I handed out the system to Unity a week ago. Now the mentors are making from it a neat package and adding some example assets and I myself am making the documentation […]

It’s some time since my post about Fedora & Vista dual boot using the Dell Media Direct button and I’ve realized that I don’t use linux at all. It’s not that I don’t like to – I would love to switch to another more customizable system, but I can’t. Windows binded me with too many […]

I’ve changed a little bit the list for last week Last week: Automatic setting the lightmaps accordingly to their name as soon as they appear in Asset folder Basic batch render script for 3dsmax, which opens max and renders&saves all lightmaps (yet hardcoded) A solution for applying materials, and setting up lightning have been overdiscussed […]

THIS WEEK SUMMARY: The main core with GUI has been done which contain a following options: A dynamic list of lightmaps (shown as buttons) Simply hierarchy display list for currently highlighted lightmap Most necessary options “Pick selected objects”, “Clear list”, “Export FBX” Optimal UV Packing: the size of lightmap spot for an object depands on […]

After some consideration I decided to change the name for a moment to make it less confusing for other people, because the project indeed is focused on the connection between Unity and Vray over 3dsmax, but the main core will allow everybody to use it for their own purpose with any software with a FBX […]

Yesterday I’ve received an information that my proposal (+ video) which I sent for Unity Summer of Code contest was accepted and I’m really excited about the system development Basically the system is automating the bake process for Unity powered games using a powerful rendering software VRay. The Unity team proposed a bit different workflow and […]

I was trying to get a matrix for a projection of any point to a line given by the following equotations: After some time of research I’ve ended with the following result: Let then Of course the result isn’t new at all, it was just a big efford for me to do that at midnight […]

Assembler programming NO. 1
This post is meant to be a short introduction to a new science branch on my blog dedicated programming in Assembler. One can think that the use of Assembler is deprecated these days, but there are still many reasons for a computer scientist to know this low-level language. The primary reason to program in assembly […]

Today, I noticed an amazing and worth memorizing thing. I turns out that fibbonacci series shows up also in graph theory in one of the simplest graphs: Where’s Fibbonacci hiden here? Well, the graph can be represented as a folowing matrix: By multiplying the matrix by itself and using induction we get:

It’s a trick that makes posible to write polish characters on your mobile in Python editor using Nokia SU-8W. All that’s needed is PyS60 installed with appuifw2 module. To write a polish letter press Alt Gr + Key, where Key is the usual key under which polish character is hiden. Few things that I could […]

Matrixes seem to have a lot of wonderful properties, for example they may help checking if given triangles represented each by three complex numbers (verticles) are simillar. So, two triangles represented by complex numbers and are similar if, and only if: Proof coming soon.

God damn. I took me about a half of an hour to Google that out… Things to do to fix Visual Studio C++ Express (Probably in most cases you don’t have to delete those entries first. (worked for me)): Go to Start -> All Programs -> Accessories -> Run, and type “RegEdit.exe” Locate […]

The polynomial argument is a very useful fact which can be used in order to prove, or justify a statement. It bases on simple fact that non-zero polynomial of k degree, can have no more than k solutions, futhermore the difference of two polynomials of k degree can also have max of k solutions if only […]

The proof for the limit points of the sequence haven’t given me a calm dream untill today. Of course the limit points of that sequence (almost intuitively) Lemma. Lemma proof. from floor function definition web have the following inequality: Now we will prove that Let where So we have Let so of course Lets consider […]
