I would like to know how can I detect “collision” when Object (like CAR) drives on the ground… You know wheels always touch the ground etc … First I thought I would just get the hight of the Vertex on which the Wheel is located… But how would I know where to look for this Vertex info in the array ( 1D or 2D ) ??? I think if I were using 2D ARRAY, I would just use the Wheels (X,Z) values, to specify the location (row, column) in 2D array where Vertex hight for this particular location is stored … Is this how it is done ??? ( I assume that my ground lies in positive X,Z quadrant ) …
Is this the way it is done to detect the distance between an Object and the ground ? Or there is more efficient way ???
Also in 3D racing games, I understand that Race Tracks for example are made using 3D programs such as 3Dmax … So if you LOAD this track ( buildings, road, trees, barriers etc ) into the memory as a whole, how will you know which part of this track data to use for collision, or computing the position of the Car on the Track, ( so when the car goes off the Track, you should hange to off road conditions etc ) …
Anyone can TRY to explain that to me ? LOL> thx in advance
