A freeform allows you to load a mesh of varying file formats such as 3DStudio 3DS, Milkshape ms3d file format, Quake III map format and OpenBSP format. Refer to the file formats article for a complete list. Freeforms include texturing and lightmapping and collision detection so it is possible to interact with and display scenes like youd see in Quake.

Freeforms are also shaded by default if a lightsource is in a scene.

Important TGLFreeForm properties and methods include:

meshobjects TMeshObjectList

procedure getextents (minextent,maxextent:TAffineVector)

Returns the size of the freeform. minextent has the minimum x,y and z coordinate of the freeform while maxextent has the maximum

procedure structurechanged
