Function Documentation

McdConeID McdConeCreate ( McdReal length, McdReal lowerRadius )

Create a cone geometry.

In its local coordinate system, the cone's principal axis is aligned with the z-axis. The cone's center-of-mass is at the origin: this means that the base of the cone is below the z=0 axis. The amount of this offset is given by McdConeGetZOffset().

McdConeGetZOffset()

McdReal McdConeGetZOffset ( McdConeID g )

Returns the distance from the z=0 plane to the the cone's base, which lies below it.

The cone is positioned like this so that its origin lies at its center of mass.

void McdConeRegisterType ( )

Register the McdCone geometry type with the Mcd system.

McdCone is often registered implicitly via McdPrimitivesRegisterTypes(), in which case it is an error to call McdConeRegisterType() explicitly as well.
