seg fault with svn r1750 - alex25 - 07-07-2007
just did a svn update, looks like lots of things changed, unfortunately i get a seg fault in ode:
Code:

never mind. i switched to the svn version of ode (as opposed to using the debian package) and now i can start the program. unfortunately the texture size setting doesn't seem to work any more, so it's always loading the high textures which makes it unbearable slow on my laptop and then when i touch the wall the car takes off and goes airborne (like a plane) so something is not quite working with the collision code.

Looks like this is the gimpact crash. For some reason using gimpact (the default collision lib in recent ODE versions) causes a crash. See this post for the work-around:

Whoa, the svn version of ode makes this work for you? Awesome. I'll have to check it out.
Yes, the collision is pretty broken. The collision detection is excellent, but the response code is still wrong somehow.
Regarding the speed, can you check out this forum post:

At the risk of going off on a tangent, what video card do you have? How slow is slow? Also, what do you get for these lines (shown on the console when vdrift starts up):
Card supports: drawbuf4 auxbuf4 multitexturing4 antialiasing anisotropy16 cubemapping shaders texture_rectangle depth_texture shadow
Card does not support:
this is on my thinkpad with a radeon card which is pretty basic but with low textures i was able to run vdrift before and get resonable fps (something like 20-30 depending on the track, etc). now i get around 2-3 which makes it pretty much unplayable.
this is the output i get when vdrift starts:
Code:
Extension not supported: GL_ARB_fragment_program
Extension not supported: GL_ARB_depth_texture
Extension not supported: GL_ARB_shadow
Card supports: drawbuf-1076669260 auxbuf0 multitexturing6 antialiasing anisotropy16 cubemapping texture_rectangle
Card does not support: shaders depth_texture shadow--alex--
