Jun 15	comment	TBN Matrix : Eye vs. World Space Conflict @deniz you are welcome :) I just want you to close the browser and open some Math book :)
Jun 15	comment	TBN Matrix : Eye vs. World Space Conflict there is no tangent space or world space or eye space. In final, you always multiply by only one matrix, which can be product of 3, as well as 30000 matrices, since matrix multiplication is associative. You don't have to give each matrix the name. You should know some basic linear algebra and low-level shader programming, then you will understand everything.
Jun 12	comment	How is good is Java as a language for browser based mmo games? Actually, I know people who write some common algorithms in "exotic" languages much faster, than me in Java. Time and memory complexity is not dependent on language. And if by "time" you mean the real time of code execution, it is not the problem of language, but of compiler / interpreter / SDK. But I think OP really does not want to know that :-D

Jun 10	comment	How to know when a bullet has hit its destination in a game with a fixed timestep? @Byte56 No, I suggest to talk about the concrete representations of abstract things, when you expect to get concrete answers.
Jun 10	comment	How to know when a bullet has hit its destination in a game with a fixed timestep? "hit the destination" is as vague, as "bullet". What is a "bullet"? there are only zeros and ones in the computer, no bullets.

Jun 8	comment	How does normal mapping really work? Have you ever tried to implement phong or at least diffuse shading? Do you know basic formulas like dot(a,b) = cos(angle(a,b)) for unit vectors a,b ? Few hours of implementing would save you years of struggling.
