This post is a result of some insight and necessary steps to get the June 2010 DirectX SDK working on a Windows 8 system, with Visual C++ 2010 express. Given the fact that DirectX 11 comes bundled in with the Windows 8 SDK, my stubbornness to change the configuration is due to the fact that … Continue reading

# Infragistics UltraWebGrid column format not being applied

Just a short post today, recalling an incident I came across recently, which I thought I should jot down here, and hopefully It’ll save someone else a headache. If you have been working with the 3rd party UltraWebGrid control for asp.net offered by Infragistics, you would have worked with columns where you might have wanted … Continue reading

# 2012 in review

The WordPress.com stats helper monkeys prepared a 2012 annual report for this blog. Here’s an excerpt: 600 people reached the top of Mt. Everest in 2012. This blog got about 5,600 views in 2012. If every person who reached the top of Mt. Everest viewed this blog, it would have taken 9 years to get … Continue reading

# 3D GAME MATH PRIMER 4: OPERATIONS ON VECTORS

In a 3D game environment, vectors are used to hold the values of points or vertices. Thus a vector would contain a coordinate [x, y, z] which represents the specific vertex in 3D space. Points are defined such by vectors because the start position of the vector is usually taken as [0, 0, 0] which … Continue reading

# 3D GAME MATH PRIMER 3: WHAT ARE VECTORS ANYWAY?

Well what are vectors anyway? The topic of vectors crop up in geometry, physics, engineering disciplines, mechanics, etc. How they are used, as well as their definitions at times, vary from context to context. Below I have listed how vectors are defined in some contexts: 1. In geometry, Euclidian (or spatial) vectors are line segments that represent … Continue reading

# 3D GAME MATH PRIMER 2: MULTIPLE AND NESTED COORDINATE SPACES

WHY DO WE NEED MULTIPLE COORDINATE SPACES? This question is best answered with a story given in the book ‘3D Math Primer for graphics and games development’ by Fletcher Dunn and Ian Parberry. The story goes that there are two cities, ignorant of each other and having their own coordinate system to map the different … Continue reading

# 3D GAME MATH PRIMER 1: THE 3-DIMENSIONAL COORDINATE SPACE

The 3D coordinate system is a natural extension of the 2D cartesian coordinate system we are all familiar with and have studied. The cartesian coordinate system has an interesting history, first documented by the French mathematician Rene Descartes in around 1637. Early work in this time period dealt with only one or two axis coordinate … Continue reading
