The hardest thing about creating 3D is where to source my MeshGeometry3D data. That's the TriangleIndices, Normals and Positions. These numbers are enormous. Lucky thing there are tools (reading Tim's blog ), I found ZAM 3D and other conversion utilities...

Recently I have this bug inherited from my good intern that WPF <Popup/> will always be TOP_MOST in terms of z-index. The bug scenario is that when you have another application (eg. notepad.exe) going on top of my WPF application (with Popup launched...

It's been sometime since I last post here. This site even come with a new blog software. Very nice. Every year during my OOF days, I worked on some hobby project that I will be using. Last year, I was doing a Stock reader for my own...

While researching for information about Avalon [ for play-n-learn sample app ], I realized that I'm always going back to the same site/blog over and over again. I thought it is nice to just compile a list of information that I'm always using from time...

I read Chris Sell’s blog and found out that the new Avalon CTP is available to public. As a member of the public I was too excited and decided to download and play with the CTP, CLR beta 2 and Visual C# Express. I was a bit worried as I have all kinds...

A little analysis of Microsoft's business according to this Forbes article.

Technology has evolved again. I've been doing MSN messenger with my mum with audio and video for about 24 months now. This is all great technologies and great video quality [especially with Logitech camera] since we have broadband on both end. The problem...
