The development journal of my FPSMMORPG... only joking. Big city full of zombies and Havok physics.

Made some structural changes today to prepare my newly created lighting system for use with the scene.
I've got my system gathering spotlights from a render list and drawing as many as possible in a single pass; it performs quite well with around 50 lights per pass. This render list is gathered by t…

I've now set up my multiple pass system, using g-buffers for lighting, this means I can render the first pass as a single quad, then use the g-buffers rendered at the same time to perform multiple, far cheaper lighting passes.
Here is a screen shot of the result:

I wasnt going to go with full blown deferred rendering, so only my lighting pass will be defferred. That is, the first pass (ambient light, sun light / shadow and light / shadow from one or more lightening flashes) will be rendered the old fashioned way; but at the same time as doing this pass, I w…

Today I expanded my shaders / architecture to support more than 1 light per render pass. Its my plan to implement a multipass, forward renderer with some use of seperate buffers. This is my plan for rendering things:
1) Render the geometry albedo with a single directional light w/ shadow map to repr…

Its been a while since I last made a journal post (over a year I think) mainly because development slowed considerably; also, ive been working on physics rather than graphics, until now, so there wasnt much to show.

Change in plans
Well, after 3 weeks of working on work for uni, and making one of those rediculously long job applications, I've not done anything related to spawning characters.
Instead, I spent the last week making a GUI lib. This was a big change in plans, but the mood struck me, and I need a GUI …

So, did a few things of interest today:
wrote a system for loading keymappings from file. The number of config files my game will use is rapidly growing. the file looks like this:
KEYBOARD
w FORWARD
s BACK
a LEFT
d RIGHT
r RELOAD
e ACTION1
f ACTION2
1 WEAPON_1
2 WEAPON_2
3 WEAPON_3
4 ITEM_1
5 ITEM_2
6 ITEM_3

I've been ignoring my game project of late due to christmas and assignments, however I have made some progress. I've finished the resource loading system, and now have a system whereby I can load any part of the game world, and load and keep track of all the materials that part of the world needs, …

Well, its a common fact that your prediction for how long something will take is usually far too short. I've started the resource management system, and it went through several iterations. Over the week I decided to work on something unrelated to the goal in the last journal entry.

Todays progress:
I didnt do anything I planned today because I was too busy with Uni work. This is likely to happen alot.
Instead I've done the following things:
I upgraded my resource loading system to allow several seperate brush files. The headers for all of them are loaded during initialisation…

Its been a while since my last journal entry, since I haven't been working on my project for a while. I didnt have any internet access for nearly a month (I cried every night) and I've been settling into a new house and university term.

New results are in! I decided not to write the header for the new file format today. Instead, I have been removing debug code from my various classes, to see how fast the system runs. Its not yet completely optimised, but its close.
After those basic improvements were made, I have cut the render-lis…

SUCCESS!
So, it turns out that VBO's are very fast indeed. Keeping arrays of vertices on the GPU side means very little increase in rendering time with a raw increase in polygons. Here is a table of results,
The first mesh, with 18k polys, is a hill made using subdivision modelling. The second is the…

I had abandoned the journal thinking that nobody read it; only 5 kind souls left comments and 2 of them were from the same person. Well, I've made some progress since 1st August, although I must confess that I did alot of procrastination.

Sorry, I didnt update the blag yesterday. I had a nasty bug in my AC3D file loader and was awake until the small hours of the afternoon (GMT) debugging it. I woke up today at 5pm. My sleeping patterns suck >:(

Yesterdays objective: Met

I didnt manage to make it render properly.
What it should look like:

Two things are missing:
1) It doesn't draw the correct tris in the right places. This could be for any of a number of reasons, but I suspect it is

This is because of my dodgy sleeping patterns. I updated yesterdays journal at close to midnight (GMT+0), so it falls in the 27th. Todays journal entry will be arriving at about 6:00am, GMT+0.
[edit: better make that 6, not 5....]
I will have screenshots by then, I hope. Preliminary tests don't show …

CURRENT PROGRESS:

Currently, I am developing the new file format that I will create. This first prototype will only contain textured polygons, and will be used as a proof of concept. This is how the concept works:

Intro
This is the first installment, and I would like to introduce my project. I have always liked zombie films such as Dawn of the Dead and 28 Days Later and thought it would be cool to merge this kind of survival disaster movie with a game in the vein of GTA.
