Making a Parametric Bench: Sketch-Up Modelling Tutorial

Parametric bench is unique furniture that is made of sections of plywood bonded rods arranged into a series of contours. This contour layout can form different organic shapes appropriate for a seating area. In this step by step tutorial, we will show you how to make a parametric bench using Sketch-Up as a 3-D modelling tool. 

STEP 1: Click the line tool, draw and plot the base of the parametric bench in angular form.

STEP 2: Using the push/ pull tool, create a space for seating area.

Angular form: Top View, Front Elevation, Right Side Elevation, Left Side Elevation, Rear Elevation

STEP 3a: In order to change the shape of the bench from angular to organic form, we will need an extension such as the 'SUbd- Subdivide and Smooth Plugin’

STEP 3b: Select the bench model> click tools> click Loop subdivision smooth> change the repeat subdivision parameter from 1 to 2> click OK. 

Result so far

STEP 4: Select the model> right click> make group

STEP 5: Select the bench model> click the Slicing tool from the Slicer Plugin tool bar (TIG_Slicer plugin)> follow the Slicer parameter set-up> click OK

STEP 6: Delete unnecessary object(s)

STEP 7: Apply wood texture to your model using paint bucket. Choose any available wood textures from the Material dialogue box.

U.P. Carillon: 3D Visualization Part 2

The UP Carillon is one-of-a-kind structure located within the University of the Philippines Diliman Campus, towering 130-feet-high, beige in color, striped with maroon accent, and topped with circular dome. My visualization of UP Carillon derives mostly from my enthusiasm to capture the same exact structural charm and scenic beauty of the plaza.

Historically, the UP carillon tower was originally constructed in 1940 by National Artist Juan Nakpil, Conservatory of Music director Ramon Tapales and UP President Bienvenido Gonzales. Finished on the 1st of August 1952, the UP Carillon is currently located at University of the Philippines, Diliman along the Osmena Avenue, bounded between the U.P. Theater and Sine Adarna. The U.P. Carillon may consider as the only carillon tower in the Philippines and in Southeast Asia that is manually played by a clavier or a wooden keyboard.

Program Used: SketchUp 8, V-ray 1.6, Kerkythea. Photoshop CS5, Gimp 2, Picasa, Nik Collection, Lunapic

Kulintangan: Gongs and Bamboos

This blogpost “Kulintangan: Gongs and Bamboos” is the second installment of our two-part 3-D visualization series in which we illustrate various musical instruments from Asia particularly in Southern Philippines. We will deal in this installment with photorealistic rendering which aims to attempts to visualize a more accurate representation of the musical instruments of the Southern Philippines. The 3-D modeling procedure of all the musical instruments was done using SketchUp while the rendering was done with the aid of Kerkythea software.

The music production in the South is inseparable from its social context in which the community utilizes the music based on their life style, customs and beliefs.  The performance of gong ensemble in the Southern Philippines expresses the concept of unity or social organization in which each individual requires a high degree of cooperation. This could only be achieved by showing synchronous sound produced while playing all the instruments simultaneously.

For the purpose of expanding our cultural knowledge pertaining to Southern Philippine music, below is some illustration I’ve made that depicts the intricacy and detailed art work of Maguindanaon and Maranao musical instruments.

Agung and Kulintang gongs

A. The Maguindaon kulintang ensemble of Southern Philippines consists of the following instruments:

  1. Kulintang- a set of eight small gongs of graduated sizes. This particular instrument acts as a main melody of the ensemble
  2. Gandingan-a set of four shallow bossed, narrow-rimmed gongs. This particular instrument usually acts as a melodic ostinato of the ensemble.
  3. Agung- frequently described as a large, heavy, punctuating, bossed, wide-rimmed gong in the shape of a kettle gong, each gong of the agung gives out the bass sound in the kulintang ensemble.
  4. Dabakan- a single-headed Philippine drum, primarily used as a supportive instrument in the kulintang ensemble.
  5. Babandir- a single, narrow rimmed gong with shallow boss used primarily as the timekeeper of the kulintang ensemble.

Other Maguindanaon Instruments:

  1. Kulintang a Tamlang- Bamboo version of kulintangan musical instruments.
  2. Saronay (kulintang a tiniok)- is a type of Philippine metalophone with eight tuned knobbed metal plates strung together via string atop a wooden antangan (rack). Kulintang a tiniok is a Maguindanaon term meaning “kulintang with string” but they also could call them kulintang a putao, meaning “kulintang of metal.”

B. The Maranao kulintang ensemble of Southern Philippines consists of the following instruments:

  1. Kulintang- a set of eight graduated gongs of bronze laid horizontally on a wooden stand in the shape of a Sarimanok (mythical bird, divine messenger).
  2. Agung- large gongs with wide rims
  3. Dabakan/ Dadabuan- conical drum
  4. Babandil- a narrow-rimmed gong with shallow boss that function as a steady beat accompaniment.

Western Musical Wind Instruments: Visual Presentation

Music can be appreciated through auditory experience. As an alternative way of appreciating music, we may also look through the different instrumental craftsmanship focusing on design, form and visual appearance of different musical instruments. For this presentation, I was able to produce different digital images of Western wind instruments through the help of 3D modeling programs.

Wind instruments generate tone through a vibrating column of air enclosed in a tube or a pipe. The two classes of wind instruments are (1) woodwind and (2) brass.

Wood winds

Wood winds, with the exception of the flute, produce vibration by means of a single reed or double reed.

Single- Reed Instruments

The principal single-reed instruments are clarinets and saxophones, both of which are made in various sizes and have correspondingly different registers.

Double-Reed Instruments

The principal double-reed instruments are the oboe, the English horn, the bassoon, and the contra bassoon.

Flute and Piccolo

The flute and piccolo (the latter is the highest-pitched instrument in the band or orchestra) produce tone by air blown across a mouth hole. In the older type of flute called a recorder, the air is blown from the end into a whistle like mouthpiece.

Brass Instruments

The tones of brass instruments are produced by vibration of the player’s lips pressed into a cup-shaped mouthpiece. Change of pitch is effected both by lip pressure and by the manipulation of valves. There are four principal brass instruments.


The horn, or French horn as it is often called, is derived from the seventeenth-century hunting horn. The horn has a wide compass and produces rich, full tones.


The trumpet has a brilliant tone. The cornet, which is similar to the trumpet, has a more mellow tone. Both are used in bands and orchestras, and there is an increasing solo literature for these instruments.


The trombone may be regarded as the bass of the trumpet, but it has a more mellow tone that the trumpet. It adds tremendous sonority and power to the brass choir.


The tuba is the lowest brass instrument of the band and orchestra. Tubas are made in various sizes and shapes.
