Hi,

I am looking for an algorithm to reduce the number of vertices in a simple polygon, with the additional constraint that the resulting (simplified) polygon must be fully contained within the original polygon.

Any suggestions?

Thanks.

Hi Leo, I would suggest using the PAL work as a starting point for your research. You can take a look at the original benchmark paper here: http://apps.sourceforge.net/mediawiki/pal/index.php?title=PAL_publications A more recent review is available here: http://3dexperiences.blogspot.com/2008/12/eva...

just load up the bullet solution and select 'ReleaseDLL' that should build bullet as a shared library on windows

What do you mean?

They are infact doing the obvious and porting PhysX to use CUDA:

soon we need to implement OpenPhysics <plug> Physics Abstraction Layer </plug> ;) And ofcourse COLLADA Physics... Can we just skip to the chase and have a useful massively parallel card with a simple and generic interface for math operations? nVidias CUDA, ATI's close to the metal, do this for the ...

Mathengine... Ipion... NovodeX... Meqon... Havok... Ageia (*)... All of them acquired. Physics engine business sucks :) If I would have a game company starting a new project, I'm not sure what physics solution I would end up using those days. Perhaps a physics engine abstraction layer would come in...

Okay, I've finally got around to updating the online graphs, so they should be a bit more up-to-date now. - Can you add the version and/or download date for each physics engine? Version numbers are there now for the engines that support it. * Suggestion for another graph: stacking benchmark, but plo...

You can use PAL (http://pal.sourceforge.net/), it supports a vehicle model for Bullet and Newton. It might be a bit too basic for your needs though, but it would make a good starting point.

has plenty of good info, but you need to dig around a bit to find it.

You can now develop and import Scythe Physics Editor assets in to the Bullet physics engine via the physics abstraction layer.

Check the PAL website:

seems interesting.

I was wondering whether Bullet could be set to build as DLL compatible by default for MSVC? To do this, the C++ option code generation would need to be set to "Multithreaded DLL", and under the Linker options, Mainfest file, "Generate Manifest" set to yes. I'm not sure how everyo...

Hi Erwin, Sorry I think that last post was a bit unclear. I certainly did not mean it to be directed at you ( or in fact anyone in particular), rather (a very poor attempt) to point out some of the issues in the development of this project. That is a bit suprising, can you be more specific which eng...

Hi Erwin, Thanks for your comments. In general, I think you should focus on performance test first. I am a bit hesitant to do too many computational performance-based tests since it will be difficult to quantify the performance overhead incurred by the wrapper itself. ( except for uncontrolled cases...

Hi,

Is there a way to read the current version of bullet library? (some kind of #define or GetVersion() function?)

If not, would it be possible to include this in the next release?

Thanks!
