1  Game Development / Game Mechanics / Re: Ball Physics on: 2013-05-15 21:32:25
Hi guys, sorry for the silence on this, I have been busy getting my application to the point of needing the ball physics and remembered I had posted this question.

The ground is on one level (no overhangs, cliffs etc) and I think using the plane (normal?) of the surface the ball is on to calculate its roll should pretty much do.

I am not even rendering the ball moving, simply want to know the path it took. I am going to begin this section of code and will be back for assistance no doubt!

Thanks again

Hi guys and gals, first post so be gentle!

I have the requirement to model the movements of a ball across a 3d terrain.

I have the terrain in an extremely high resolution of data, which I currently (for testing purposes) have exported to create a surface (terrain) that is 20,000 polygons (triangles) in size. Its roughly 100 squares by 100 squares with each square made out of a pair of triangles.

The surface does not need to be in that layout, but as I say thats just testing at the moment whilst I find out the best structure.

I would like to simulate a ball rolling across this surface, and was wondering what peoples views are on either,

1) using one of the 3d physics engines out there, and if so any recommendations for this function?
2) simply calculating the angle of the polygon the ball is on and calculating the roll myself.

I am not scared of the maths involved in doing it myself, but if there is a simple library out there then simply for speed it makes sense to use that.

Id appreciate any feedback from the forum.
