Contributions to Recast/Detour

08 October 2013 // recastdetour // masa // navigation // reaching for Disqus...

In a previous post I’ve announced that, as a part of our work on MASA LIFE, the team will work with Recast/Detour and that we would release our updates to the community.This have been effective since the beginning of the summer and we’re just releasing today a new version which is the first to be used in a released version of MASA LIFE, the upcoming (if all goes well, this week) v1.2. Our work is [...]

LIFE with Recast/Detour

21 March 2013 // recastdetour // masa // navigation // reaching for Disqus...

I sent this mail earlier today to the Recast/Detour mailing list. Hello, I’m working on LIFE, the new AI middleware MASA is showcasing at the GDC next week. I am sending you this email to announce that LIFE uses Recast/Detour as its built-in navigation solution. I’d also like to explain how and what we will contribute to this great project. We are committed to open source our development on Recast/Detour for the benefit of the [...]


Formation Sketching

09 November 2011 // navigation // paper // reaching for Disqus...

I have updated the Group navigation state-of-the-art report with an interesting article I read a few weeks ago: * Qin Gu and Zhigang Deng. Formation Sketching: An Approach to Stylize Groups in Crowd Simulation. In Graphics Interface. University Houston, Delmar Thomson Learning, 2011I’ve also set up a static page for the report. [...]

Airport hall populated with Golaem Crowd

15 September 2011 // golaem // crowd simulation // navigation // reaching for Disqus...

A new showcase video of Golaem Crowd has been published a few days ago. It features our new integration with the rendering engine VRay, but most importantly (from my point of view) it shows the capabilities of our navigation engine. The animation is not that good though, especially compared to the new things we’re developing.Anyway this is a great showcase for the navigation engine I’ve been developing since more than 2 years. The path following [...]

Group navigation state-of-the-art report - Part 3, Who's in charge?

19 June 2011 // paper // navigation // reaching for Disqus...

The full article is available here.Who’s in charge?In the previous part, we studied how group members are able to maintain cohesion or stay in formation. In this part, we’ll study how the group, a whole, is able to make navigation decisions: path planning, path following, steering (including collision avoidance) and formation changes.AnchorWhile some behavior might be decentralized (c.f. part 1), in order to leverage groups in a context where we need to make them go [...]

Group navigation state-of-the-art report - Part 2, Stay Grouped!

19 May 2011 // paper // navigation // reaching for Disqus...

The full article is available here.Stay grouped!In order to get a valid simulation of group navigation we first have to design the behavior of the group members. In this part we’ll study two families of methods to obtain groups: using local rules or following a designed formation. Finally we’ll focus on how a member’s individual navigation behavior is affected when part of a group.EmergenceIn most modern navigation engine, the simulated entities are autonomous, their behavior [...]

Group navigation state-of-the-art report - Part 1, Introduction and Taxonomy

08 May 2011 // paper // navigation // reaching for Disqus...

The full article is available here.IntroductionAutonomous human-like characters being able to navigate in a 3D environment finding their paths and avoiding collisions while exhibiting a convincing behavior is now fairly common. The popularity and the quality of recent work (Van den Berg, Lin, and Manocha 2008; Pettré et al. 2009; Ondrej et al. 2010; Mononen 2010) shows that the simulation of hundreds of navigating entities is now within the reach of almost everyone. But most [...]


CASA 2010 report (part 2)

30 November 2010 // conference // crowd simulation // navigation // reaching for Disqus...

I’ve been pretty lazy on this blog this past months… Anyway here’s the end of the CASA report.Crowd Simulation WorkshopThere was many presentations during that day, more or less interesting, a few of them staid in my mind since then. The first one was titled “On the interface between steering and animation for autonomous characters” and was presented by Petros Faloutsos.The authors worked on a problem that every one trying to work on autonomous characters [...]

CASA 2010 report (part 1)

23 June 2010 // conference // crowd simulation // navigation // reaching for Disqus...

Well It’s been a long time since I posted here… I’ve been pretty busy since the beginning of 2010. Anyway, here’s a report of the part of this year CASA I attended to.CASA, the yearly conference on Computer Animation and Social Agents, was held in St Malo, France, from 31/05/10 to 03/06/10 (further information here). As its name implies, the conference focuses are: Animation techniques (motion capture, motion control, physics-based animation…), Social agents (emotions, facial [...]


Aggregate Dynamics for Dense Crowd Simulation

30 November 2009 // paper // crowd simulation // navigation // reaching for Disqus...

Ming C.Lin’s lab latest work in crowd simulation has been featured in two recent publications from MIG (International workshop on Motion In Games) 2009 and SIGGRAPH Asia 2009 (the article is already published on the author’s website). The method presented int those articles, particularly the latter one, is designed to simulate the navigation behaviors of tens of thousand pedestrians at interactive rates. Let’s see first the eye candy ! Impressed ? So do I, let’s [...]
