Yeah. My experience was basically that, with every improvement I came up with, the closer I got to a "classic" A* implementation. I kind of wonder what the known lower-bound is to find the best path from A to B in a universe of size N, and how far A* is from it... Hubis fucked around with this message at 17:44 on Oct 12, 2010 |

I reinvented Dijkstra's algorithm in QBasic when I was a kid. Reinventing A* would be impressive if you had no prior knowledge.

It's been a while since I last wrote a software renderer and I wanted to try out the halfspace method of rasterising (as opposed to scanline). Still got a whole load of optimising to do. Video.

I spent most of the day working on an algorithm that grows trees procedurally for an upcoming game. You can't see the growth in action, but the results are looking sweet. Now if only I can do decent leaves.

After two university programming courses and dicking around around with some very simple games (space invaders!) I decided to try a roguelike:  It doesn't really do anything yet besides draw some tiles and let you walk around but it's been very educational nonetheless. I'm using Java's Graphics2D to draw a tileset shamelessly stolen from my Dwarf Fortress install instead of text because I couldn't get AWT to draw fonts that didn't look like poo poo.

I hosed my windows install and didn't back much of anything up so I ended up starting to rewrite my lovely software renderer for the last few days. Design is a bit smarter and a bunch of stuff is vectorized now like surface manipulation, the math stuff like matrix and vectors, and all the transformation stuff. It also actually has a proper timer so I can set / get the FPS... though it seems too high to get anything meaningful if I leave it uncapped in a simple scene at a low resolution. It hasn't regained the ability to draw lines yet but if you look carefully you can see the vertex pixels that make up my cube   Click here for the full 676x340 image. It's actually less to look at than the first post I made on this because I had wireframe triangles working then... but this is totally more impressive in the underlying implementation of everything even if you can't see it.

Ah, the best part about software development. All that effort and clever solutions and such yet the poo poo looks the same. Cool project though.

I felt inspired and got wireframe back in   Click here for the full 676x340 image. Next up is actual model loading so I can get away from this cube already and maybe stress it a little. edit: Testing out my new SSE transformation stuff. With no drawing, it plows through 1,048,576 verticies at about 12 fps. It's about 90%~ faster than the x86 version. Kind of ridiculous scaling, really surprised me. About 327,680 clocks in around 38 fps.I still have a lot of room for improvement. Maybe I'll look into threading stuff eventually, as well. slovach fucked around with this message at 09:34 on Oct 16, 2010 |

I am pretty bad at maths (and typos) so this actually took a couple of days to get working, but now it does so I can actually work on game-side stuff like sliding along the plane of contact, and importing world collision from Blender or whatever. https://vimeo.com/15899261

Scaevolus posted:I like this. Just to give some follow up to this comment, I doubled the price and noticed no appreciable drop in sales, insofar that there were any. At £1.49 I seem to get a sale every couple of days. What I've found interesting is that it's been downloaded ~4000 times since my last post in this thread, at a greater rate than other projects of mine I think are better. I suspect this is because it gets twice the exposure - people might see the paid for version and seek out the 'Lite' version. To contribute a screenshot  I added a few variants on the maze building algorithm. Just providing a bias towards turning left makes it very reminiscent of climbing plants. It makes me want to build some sort of tropism simulator, I imagine it could produce some rather cool effects.

I'm drawing using points and lines, with GL_LINES doing the drawing-to-screen. Right now I'm just using an ArrayList with lines and iterating all the members of said list. e: With slight fear of posting too many pictures, here's a Sierpinski Triangle as well. This is way too much fun! Made a couple of new classes for this one, still doing pretty much the same thing (just with triangles instead of lines.)

I know what you mean - it was hard enough to get our brothers to use google docs or, god forbid, dropbox. Then again, I was shocked to hear other chapters and houses not even having an email listserv, let alone coordinated google docs or an internal brother website system. I imagine convincing outside fraternities to use software like this could be quite tough. I'll mention it to our current web chair and see if he is interested in looking at it. Being a grad I don't have much pull anymore, but I can knock few heads around when I come back to drink sometime.

Grats on being able to keep your 'house' in RHAPs after the sophomore housing clusterfuck kicked all the upperclassmen out. I think Delta Phi was able to keep their little string in Colvin 14-16, too.
