Elysian Shadows

If you are using a shader to update positions you don't even have to copy data between CPU and GPU once the particles are emitted. I'm doing this for a thesis and I can handle ~200,000 particles (billboards) with inter-partical collision and ~1,000,000 without at ~60 frames with a gtx8800. Keywords...

This is not mutually exclusive. It's actually pretty straight forward to combine both. Nice, I personally haven't looked into using them as a particle system, just new they would be faster (I assumed GL_POINTS was limited to immediate mode as I have only used it for debugging things). Now that you ...

I don't know how the hell I missed this. I quit following the thread for a few days. XD Well now you know the error of your ways and it won't happen again. Just set this thread to your homepage :P Gotta say man, looks uber polished, nice work. hope it sells like chocolate dipped bacon. (if you were...

Well in all honesty the code has gotten to the stage where it's about as pretty as dog vomit. I will release the source (or parts of it) regardless, though I'm sure I will feel great shame having everyone look at it :P and I doubt most of it will be of much use for learning given how untidy it is. I...

Actually if you are creating a particle system I would opt. for point sprites over the use of VBO's.
Here are some samples, go a little down the page.

I say when it comes to a map editor what to create/use depends a lot on the game. For something like a heavy physics based game you would probably want it running inside your engine/game so you can regularly test out levels without any difficulty. For my iPhone game I only needed something simple ho...

It uses the iPhone SDK. The game is almost entirely written in C++ code using openGL ES for rendering. There are 2 or so classes that are written in Objective-C that I have wrapped around. The engine is all from scratch, including; rendering, physics, image loading, animation, entity management, sta...

In my time living out of home and going to uni I haven't ever had nor needed a bathroom to myself. But then again I would probably be comfortable living in a shed if it had running water. is it worth having part-catered (ie 2 meals a day free), or just staying self-catered? Food! As a student you do...

Well I wasn't going to throw my opinion in but that picture just supported what I had to say perfectly. That image is by far the most bigoted/ignorant thing I have seen for a long time, congratulations. Some Muslims (for some reason this word is synonymous with terrorist in some peoples minds) belie...

Behold my ability to triple post without any sense of guilt or shame. Bwahaha i am truly a monster! Here are a couple of teaser screenshots. http://samzeid.com/iPhoneGame/22May2010/IMG_0029.PNG http://samzeid.com/iPhoneGame/22May2010/IMG_0033.PNG I'm planning on doing a youtube video, what sort of t...

if your tiles aren't on screen, don't draw them :D

The other calculations barely cost anything compared to the cost of rendering. Always try and draw as little as possible.

If you want to get crazy with optimisation you could consider grouping the tiles in a quad-tree like fashion.

Do 1 elective unit that is full of girls. Computer science has like a 1:100 girl to guy ratio. Not sure how it is in America but from where I am your lecturers aren't going to force you to work or yell at you for slacking. This means if you take it easy and leave things last minute you will fail cla...

Some suggestions on how to improve the piece: Here's my edit to try and show what I'm doing, admittedly it's not perfect: http://img517.imageshack.us/img517/5088/editquicky.png *Pay attention to the different 'forms' (the 3 dimensional way you depict your object). Your hilt though lit from the right...

If you are trying to work out whether a number is a multiple of another number you are going about it the wrong way. I'm not 100% sure what you are asking but I hope this helps: see % operator (modulus). you can even go on google and try it out, google this: 26%13 try changing the numbers about look...

Haha feel the mighty sting of VBOs as they explode the crap out of your models. However when it draws you have made a step in the right direction, it tends to mean you are almost done with fiddling around with them. Very nice job. ... How old are you again... 17, expect to be working as an industry ...
