XPLM_API void XPLMDrawObjects( XPLMObjectRef inObject, int inCount, XPLMDrawInfo_t * inLocations, int lighting, int earth_relative);
XPLMDrawObjects draws an object from an OBJ file one or more times. You pass in the object and an array of XPLMDrawInfo_t structs, one for each place you would like the object to be drawn.
X-Plane will attempt to cull the objects based on LOD and visibility, and will pick the appropriate LOD.
Lighting is a boolean; pass 1 to show the night version of object with night-only lights lit up. Pass 0 to show the daytime version of the object.
earth_relative controls the coordinate system. If this is 1, the rotations you specify are applied to the object after its coordinate system is transformed from local to earth-relative coordinates -- that is, an object with no rotations will point toward true north and the Y axis will be up against gravity. If this is 0, the object is drawn with your rotations from local coordanates -- that is, an object with no rotations is drawn pointing down the -Z axis and the Y axis of the object matches the local coordinate Y axis.
