View Full Version : Tracks over water, outdoor scenery?

I'm sure you have all seen video footage some place or another of people on motorcycles (or snowmobiles) riding across water, right?...

Well how about in Trials 3 (or whatever the next version will be called) you have part of the track go across the water? You lean back too far, you loose speed and sink, you lean forward too far, you catch your front tire, splash and sink...

I don't know how the heck the physics for such a thing would be done but I think it could be a pretty awesome change in the environment?

What do you all think?

or how about not the idea of trying to drive on top of water but more really to add in obstacles like eg pig trough or horse trough (pronounced trof - couldnt remember how to spell it lol)

these could be filled with water which you need to drive through, obviously wet tires on steep obstacles call for some slippery skills :p

if there are players around my age (in uk) they may remember a trials program on telly remembered as "Kickstart" water hazards were a common element in these courses.

dude that is an awsome idea http://forum.redlynx.com/forum/images/smilies/icon_biggrin.gif http://forum.redlynx.com/forum/images/smilies/icon_biggrin.gif http://forum.redlynx.com/forum/images/smilies/icon_biggrin.gif http://forum.redlynx.com/forum/images/smilies/icon_biggrin.gif http://forum.redlynx.com/forum/images/smilies/icon_biggrin.gif http://forum.redlynx.com/forum/images/smilies/icon_biggrin.gif http://forum.redlynx.com/forum/images/smilies/icon_biggrin.gif i agreeeeeeeeeeeeeee and.. i think i know you...

Slippery surfaces (different surface grip in physics engine) is must to have in the sequel. Would be fun to drive on blocks of ice for example.

Water is a much more tricky thing to implement, but I definetely agree that driving in water should be implemented in the future (Trials 4 maybe?). Good thing is that new physics engines start to support water simulation and soft body dynamics. Problem currently is that you need dedicated physics hardware (PhysX board) to even run a small bit of physically correct water on acceptable frame rate. But both NVidia and ATI are bringing physics processing to the graphics cards and the newest cards (Radeon 4870 and Geforce GTX 280) have around 1 tflop of floating point processing muscle. Intel's new forthcoming chip has 8 cores and lots of floating point vector processing power. In a few years full water simulation in games should be possible using mainsteam hardware, and likely the next consoles ("Xbox 720" and "PS4") will have enough power to simulate water as well.

Actually riding across the surface of water is unrealistic for a trials bike; it can be done with some vehicles, but requires specific tyres and probably more power than a trials bike can deliver.

More detailed physics processing, like variable friction coefficients for different surfaces, is a must have, but full particle processing for water would be overkill, especially considering that the physics engine needs to be unified for all system levels for the sake of global records. Simply having water slightly resist the motion of any components of the bike which are immersed would be sufficient, along with any non-essential graphical results from this (ripples and splashes).

Only a simple model would be required to give a reasonably accurate representation of what riding a trials bike under some amount of water is actually like.

But it would be great for outdoor scenery, i.e. just a waterfall in the background or some kind of river, were you have to jump over, instead of jumping barrels of fire etc... http://forum.redlynx.com/forum/images/smilies/icon_wink.gif
