Can i Load whole collision geometry at the beginning ?

[rocksvick]

i am newbie to bullet . i am working on car game . i want to load my track's static collider using btTriangleIndexVertexArray . but i think if i will do that , it will degrade performance because a lot of collider data will be loaded. so is there any way so that only some part of collider data will be loaded at a time . collider data will consist of road data , side colliders etc .

It is best to load the whole collision geometry from the beginning, whenever possible. Generally I would only recommend streaming collision data if the full data doesn't fit inside memory, not for performance reasons.

Bullet uses efficient acceleration structures for both broadphase and midphase (triangle mesh).
