3D Models for Physics Repository with Cycles in Blender


In addition to my previous models for Physics, these are few more. Following are the existing models on the OSCAR website, whereas, just below them, is an images showing renders of the same models in Cycles:

Screw gauge: It is a device, sometimes known as a micrometer, incorporating a calibrated screw used widely for precise measurement of small distances in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers.

Jockey: It locates the Null point deflection after taping and is a device that has almost zero resistance.

Vernier Caliper: The vernier, dial, and digital calipers give a direct reading of the distance measured to high accuracy. They are functionally identical, with different ways of reading the result. These calipers comprise a calibrated scale with a fixed jaw, and another jaw, with a pointer, that slides along the scale. The distance between the jaws is then read in different ways for the three types.

Here are the initial renders in Blender 2.49:

Screw Gauge, Jockey and Vernier Caliper (Blender Render)

Here are the renders in Cycles render Engine:

Jockey, Vernier Caliper and Screw Gauge (Cycles Render)

Jockey, rendered with Cycles has two materials, a black one, which has a Mix shader, with Diffuse and Glossy, as the shades and the other one is metallic, steel, which again uses the glossy material. My Colleague, Pankaja helped me with the metal texture.

Screw Gauge, rendered with Cycles has four materials, three shades of Grey, with glossy materials and varying roughness and the last one for the UV mapping purpose, to display the scale on the surface of the model. Two of my colleagues, Bhavya and Nitin, helped me out with the UV texture.

Vernier Caliper, also rendered with Cycles has two materials, a shade of Grey, with glossy material and some roughness and another one for the UV mapping purpose, to display the scale on the surface of the model.

Following are the settings for the metallic material:
