This seems like a pretty good starting point for that sort of map gen.

Yep, that was linked somewhere here and was my initial inspiration. I didn't end up using much from it except the basic idea though. Most of the above code is based on this great library: https://github.com/gorhill/Javascript-Voronoi

This isn't a screenshot, but I'm working on a little level editor for a game I'm working on and I've started uploading short videos of my progress. https://www.youtube.com/watch?v=cNEdipE6nAs It's pretty simple so far, I got auto-tiles working for the grass tiles, flood fill, and I can save and load maps. I'm having a lot of fun working on it. At some point I will have to make a start on some actual gameplay!

You may be passed the voronoi point, but in case you are still tooling around: d3.js is an excellent visualization toolkit, and they have voronoi tesselation as one of their default things. d3.js and an example. Also, d3.js is just fun as hell to use.

Got the first bit of Hot Tin Roof environment art today. I'm pretty dang excited to see how it looks in-game: (ignore the iffy lighting / weirdly off-center globe, he threw that in as a quick test of the mesh in a locally lit environment)

I'm using a library I linked above to build the diagram, which is based on the exact same algorithm as d3's, so it probably wouldn't be much different. It's nice that d3 does the rendering for you, but I'm doing a lot of custom stuff there anyways, and d3 seems to be built around SVG whereas I'm doing canvas drawing. I'm definitely going to hold onto that link to look into in the future though. I actually do a lot of data visualization in my day job and it would probably come in handy for some of that.

You're more dealing with the "how" to display it visually. Which brings the point of svg vs canvas. d3 actually just operates on DOM. You can use whatever you want. Ya, my day job tends to revolve around visualization as well, and coming from java (prefuse ugh) and .net libraries into d3.js was an eye opening moment of just how over the top and burdensome other libraries are. I seriously have fun using d3.js just because of how to the point and powerful it is. Luminous fucked around with this message at 16:56 on May 2, 2013 |

 I finally figured out the order of matrix transforms to implement separate object, world, and camera spaces. I have implemented a simple camera that can rotate and pan on any arbitrary axis too. I've wanted to understand the matrix transforms for 3D graphics for a while now and I'm pretty proud that I've finally managed to get it. I chose python because there is less overhead for the code. edit: I managed to figure out back-face culling too, but it is turned off in the screenshot.

Some really impressive stuff on this page!Woodsy Owl posted:
3D graphics are really fun to play with, good luck! I just finished the ray tracer for the online course a few days ago. It basically just does the minimum requirements: triangle and sphere intersections and arbitrary transformations thereof, Lambert and Phong shading, shadows and reflections:  I also added the GUI and partial-screen updates for instant feedback and rolled my own multi threading instead of using OpenMp, this time it actually it almost quartered the time instead of increasing it  . I really need to implement octrees or something to speed up the ray-object intersection testing, and then I could finally focus on rendering the drat teapot.

mobby_6kl posted:... rolled my own multi threading instead of using OpenMp, this time it actually it almost quartered the time instead of increasing it I'm sort of curious what went wrong here. I think for my old ray tracer I just added a single #pragma omp parallel for and my rendering time got quartered. Anyhow, if you're looking to add a neat little feature to your ray tracer before tackling tree structures, I'd recommend adding supersampling to reduce jaggies. Basically you just create multiple rays for each pixel: http://en.wikipedia.org/wiki/Supersampling. It's really simple to implement and makes the renders look a lot neater!

Have a look at this edX course, which is what got me from next to zero linear algebra and totally zero 3d math to that ray tracer in a few weeks. It just concluded earlier this week, but you can still watch all the videos, in particular the introduction lectures cover all the math you'll need, which isn't that much, really. Foiltha posted:I'm sort of curious what went wrong here. I think for my old ray tracer I just added a single #pragma omp parallel for and my rendering time got quartered. I just wasn't being very clear/specific there. Enabling OpenMp didn't just didn't play well with my sampler and resulted in weird results. I got scared because I couldn't really see what it was actually doing, and rolled my own. The decreased performance happened in another project of mine where I was doing some Monte Carlo calculations, but I can't blame OpenMp for that as that was also my own half-assed solution .So now I start a bunch of threads and have them pick up rendering tasks. When they finish, they submit the results to my film class, and repeat. At the very least, it seems to replicate the observable behavior of some real raytracers, if not the outcomes. I'm sure this could be replicated with OpenMp as well, but at least I learned a bit more about concurrency. And thanks for the supersampling recommendation, adding that seems like a good idea before I start messing with trees, which look like serious business.

mobby_6kl posted:So now I start a bunch of threads and have them pick up rendering tasks. When they finish, they submit the results to my film class, and repeat. This is what I ended up doing with my ray tracer. The limiting factor with multi-threaded ray tracers is contention for the frame buffer I've found. With bidirectional path tracing, any thread can write to any pixel, so you start needing sample sorting jobs, kernel sampling jobs, and tiled frame buffers. Much is made of the parallel nature of ray tracing, but once you start doing anything more complicated than forward tracing, you run into all the same threading issues that other, less parallel friendly algorithms do. Speaking of ray tracers, I haven't posted anything from mine in a while:  A day and night render of an industrial space that were part of an architectural vis project that got canned half way through. There was originally going to be a backplate, which is why the sky is black.

Over the last week I've started writing an ORM for Javascript's IndexedDB and WebSQL.  This is the API so far: https://gist.github.com/MalucoMarinero/5519900 The only thing that needs to change for me to use one or the other is the name given to the initDB method. Pretty happy with this so far, working using promises has been very enjoyable once I got my head around them, made it very straightforward to put together some of the more complex stuff I found in putting together asynchronous calls.

Workin on an iPhone app that lets parents send photo postcards of their baby to grandparents and relatives. Doing all the design myself too, coming along pretty good I think:    Already have a backend for my other app lulcards, this is essentially a re-skin of that with a few new baby-specific features.

Ahh, steckles! Really glad you showed up, I remembered someone posting amazing renders here, but couldn't find any of the older posts. From this post it seems like you actually found a practical/business application for your renderer? How is that going, I mean besides this particular project being canceled? For now this approach to multi-threading is working just fine, but I can definitely see the frame buffer becoming a bottleneck and being a pain in the rear end to manage. Thankfully, I'm still quite far away from bidirecional path tracing so I won't have to deal with this for a while still .piratepilates posted:Yeah well here's mine

Grawl posted:https://www.google.com/search?btnG=1&pws=0&q=travel+blog The plan was to build on that. There are so many features I want to add to it but without the rest of the site it just feels like a part time maps mashup. I've been spending most of my time fleshing out the site once I got to that point with the map. In the couple of months or so flights are going to be coming so you can link up journeys across different continents and separate locations more easily. It will be awesome, but I'm still trying to find a way for more people to use it. e: The cool thing about all of it is that you don't need to upload pictures at all, though it would be helpful to anyone viewing your trip, we find pictures of locations along the trip and automatically show a preview of what you may see. Funny thing is that it only does that 50% of the time. The other 50% is completely unrelated stuff, like old people getting back massages or something. Bugs and such. As for looking like twitter, well bootstrap tends to do that but it speeds development up a lot since I hate futzing around with css and html. fuscus fucked around with this message at 23:14 on May 7, 2013 |
