Modeling Queen

As always, begin by creating a new database using the following command in the command prompt:

opendb queen.r ENTER

The King piece and the queen differ only in the top part. So, we will reuse the commands we used in the upper section. Type in the Command Window:

in base.rcc rcc 0 0 0 0 0 0.7 2.25 ENTER

in body.trc trc 0 0 0.7 0 0 2.2 2.25 0.85 ENTER

in curve.tor tor 0 0 2.9 0 0 1 3.2 2.4 ENTER

in neck.rcc rcc 0 0 2.9 0 0 0.5 1.4 ENTER

If you look closely, the only difference is the height of the headmid.trc and the top section of the queen is a sphere. So, type:

in headbottom.trc trc 0 0 3.4 0 0 1.5 0.8 1.4 ENTER

in headmid.trc trc 0 0 4.9 0 0 0.6 1.4 0.6 ENTER

in headtop.sph sph 0 0 5.6 0.4 ENTER

The portion of the sphere at the top is slightly larger in size than a semi-sphere. So, the vertex of the sphere is 0 0 0.5 i.e., vertex of headmid.trc + height of headmid.trc + 0.1 . The value 0.1 is added to make it slightly larger than a semi-sphere.

The output is:

Make a region using the following command:

r queen.r u base.rcc u body.trc - curve.tor u neck.rcc u headbottom.trc u headmid.trc u headtop.sph ENTER

The front view looks like:

Now, comes the part of assigning the material properties and finally Raytracing the design. Type:

mater queen.r plastic 0 0 0 0 ENTER

B queen.r ENTER

After Raytracing, the queen in Front view looks like:
