pure virtual

Set the size of the emitter where the particles are sampled. Default value is (1, 1, 1). Note that the interpretation of the emitter area varies depending on the emmiter type:

EM_POINT: The area is ignored.
EM_BOX: The area is interpreted as width X height X depth.
EM_CYLINDER: The area is interpreted as the bounding box of the cilinder. The cylinder is oriented along the Z-axis.
EM_ELLIPSOID: The area is interpreted as the bounding box of an ellipsoid shaped area, i.e. a sphere or squashed-sphere area. The parameters are again identical to EM_BOX, except that the dimensions describe the widest points along each of the axes.
Parameters

[in] _size Size of the emitter (width, height, depth).
