    OpenGL Local Space Coordinates

    Just a quick question really - when defining an object's vertices in local space, is the convention to keep these in the range -1.0 to 1.0 (or -0.5 to 0.5) and scale the object as it is drawn into world space, or not to bother with this and instead to use more arbitrary values in local space? Thanks.

    just do as you feel comfortable. local space is usually land-of-do-what-you-want.

    there are some conventions which make sense, e.g. to put the origin somewhere near the center of the model or to align axes of symmetry in the model with axes of the coordinate system; but in the end whichever serves your purpose will be fine.
