Analysing Landscape Architecture

Derong Kong



Introduction

The series landscape architecture will be analysed in this report through a series, CAD

drawings, Photoshop edit, 3D models and rendering in Sketch up by V-ray islandscape architecture beside River Thames designed by me.

Above images show the landscape architecture sits at Oxford beside Thames. This is

an attempt acts in an art way to explore the possible relationship between Thames and

architecture. The landscape architecture used as a slide catches silhouette of

movement. The Thames as a liquid memory in the same time reflects the silhouette in

water. The theme of this landscape architecture is Thames flows with time and reflects

the image around the river as a shift slide. It would catch the movement in particular

moment, and then this imagination would flows with time in different forms and ways.

The context of the landscape architecture will be explored with a 3D model and



rendering in Sketch up by V-ray, then secondary edited in Photoshop.

The material of landscape architecture is collected form local materials mainly consist

of branches. The framework is weaved by branch by their interaction, then overlap

this framework with translucent material. It would show different forms of construction and shadow. It will be analyzed by series drawing, 3D models and

renderings, as following images show.



Site Context

Use aerial photographs of the site from the Google earth and combine with survey

images, then use Auto CAD to edit it to get the general site plan. The series landscape

architecture has been built in 3D model by Sketch up and put it with site model. This

is analyze give a direct show context of landscape architecture and environment. The

site model above represents the series landscape architecture within its immediate

environment context of river and path, bridge. In this big scale the landscape

architecture’s scale and form with it surrounding can be saw clearly. The series

landscape architecture built along the path and bridge, and shows its position with the

river. When people walk on the path they would walk through the landscape

architecture, which is parallel with river. So the people’s movement would be possible

to reflect on the river.

First landscape architecture’s plans have been set up with the site images and

landscape architecture’s footprint using the plane to from sectional information in

order to begin modeling site and landscape architecture. The landscape architecture ismodeled by creating a series of simple forms from lines, such as the 2D plans



becoming floor, each line collectively becomes a plane 2D form which extruded

becomes a 3D form which together build the form and space of the building in its

entirely, as following images show.

Second the further work on the site model, it apparent show the landscape architectureon the path which it sits, and the river flows beside it. This site model also shows the

other building’s around it and represents the landscape architecture’s quality

compared with surround environment and constructions. In this process I found that

when using Sketch up it is much quick to start with a model and continue work on

early drawing and model I have done before instead of import it to other software.

Compared with other 3D software Sketch up is very convenient for initial design

process. It builds the 3D form from a number of 2D planes, but when I edit it also

combines with the quality of solid model and surface model. It can modeling complex

model as a solid model to change the form of the model directly, or when I only need

to change one surface I can edit one surface by double click it to choose it. This is

very flexible in computer aided design.

The rendered images of the site model successfully show the landscape architecturewithin its context in terms of form and scale with surround environment, also in the

terms of colour and texture used into the surrounding environment. At this scale, it

clearly show the landscape architecture related to the path, construction and river. In

this way the Sketch up model has been an easy and quick way to show the landscape

architecture context with site accuracy. In this big scale the detail of the site and

landscape architecture and the relationship between people can not shown in this step.

Those can be shown in next step in small scale which can be apperceived by people’s

perspective.

When computer aid design compared with hand drawing, the main advantage is its



speed, accuracy of scale and form, multiple edit and lower hand drawing skill demand.

Through computer aid design I can modeling a building quickly and accuracy, then I

can have a clearly view of the building and the site round it. This design process can

edit time after time, I can delete or add anything. But computer can not express some

of my draft idea flexible or fluent. It would work out a line if I give it the order. Itwould not work as free hand drawing would not give me possible to express the

unclearly idea, the following image show the hand drawing combine with the Sketch

up model during the design process.



Landscape architecture Model

The scale of second model images above enables me to explore the landscape

architecture’s form, scale and detail relate to its surface. At this scale the model is

possible to show the surface, material of the landscape architecture which compare

with site model can give me a further detail about the landscape architecture and

context with site. This scale of model can show the quality of material, framework of

landscape architecture and the quality of light that the framework and material create.

Compare with hand drawing and physical model. The computer model can be used

time after time and copies can be saved throughout the process of the design, so that

the different attempt and process of model can documented and discussed. The

computer model can be used to generate different 2D drawing, such as plane, section

plane, rendering which can export in Sketch up directly, as following images show.

Those 2D drawings can be edited in Auto CAD which is accurate and revised within

the same model. But the physical model can give user a directly view of the landscape

architecture, such as its material, the feeling of touch. It is more veracious to user and

make user much familiar with the landscape architecture or building.

The images following show the model rendered and explored in Sketch up to better

reveal the framework, surface and spatial relationships. They structure the landscape

architecture and create the effect of light. Those pictures effective in describing how

the fabric framework and translucent material enclose the internal space of the

landscape architecture also show the quality of light as textured. The images also

show how the effect of the light would be created when people walk through the

landscape architecture. The silhouette of the people would reflect on the translucent

material, while the branches of fabric framework would slice the shade to differentshapes. There also have different sizes of holes correspond to the branches would let

people see the external environment and let people see them form outside.

In the representation of Sketch up the colour palette and rendering is quit easy and

fast. In the colour palette it have the basic color and some real surface stuffs which

can aided to the model directly and quickly. This is an advantage during the design

when I modeling the landscape architecture I can quickly have preview it as a design

process. But compare with other 3D rendering software Sketch up’s rendering

sometimes is difficult to show a realistic texture or colour to archive the real texture

or colour found on the site.



Effect of light

Fabric framework and translucent material

Caused by the limited rendering the model can not show a realistic view of the site.

Then I copy images of model and export it into Photoshop and edit it with survey

photographs to better match the environment around it. In the Photoshop through this

montage way the image can give me a more exactly and realistic view of landscape

architecture and context with site.



The advantage of exporting the model into Photoshop as an image is that I can

secondary edit the model image to make it achieve my demand. I do not need to obey

the class or component of model to render the model and I can render arts of the

model image which are in the same class or component. Through the secondary editin Photoshop I can edit and overlap different images together to make a more realistic

quality, as following image shows.

Montage at Oxford



Perspective view

Because the landscape architecture can not build up, so this attempt would mainly

processed on the Sketch up model to give people an imagination. The images beingviewed form an average human level and the views are taken form positions where a

person would be if walk around the landscape architecture in Sketch up. User can

walk around the landscape architecture as they walk in the real world as the following

images show. This is very useful to explore the form, material and scale of landscape

architecture both externally and internally with its context. User can relate their scale

to the scale of landscape architecture. The landscape architecture can be discussed and

understanding with its site. It is very useful in the design process to see the possible

view of landscape architecture and discuss it with design partner or client.

Perspective views

But the limitation of Sketch up is that when it is close to the model it is easy to walk

over or into the landscape architecture. There is little hard to control the desiredperspective view when it is close to landscape architecture or inside. And I feel it have

little distortion when the view position is too close the landscape architecture or

inside.



The light

The framework is consist different size and shape of branches which would create

different shade and overlap with people’s silhouette. The framework cover withtranslucent material, then make some holes on the translucent material which is

correspond to the fabric framework to let the light though the translucent material.

This provides landscape architecture surface ability to create different qualities,

intensities and shapes of light and shadow both internal and external.

The image above is the basic component of the model, use this component I can copyit and use it structure different length and form of landscape architecture in Sketch up.

It also can create different quality of light produced from the surface.

The rendering in the Sketch up is quite simple to show the shadow relationship with

black and white. It can not show the light created by the framework and texture much

realistic. This rendering is edited by the Sketch up-Vary and Photoshop with texture in

order to show the much realistic light imagination. The following images show the

imagination of landscape architecture in the night, which has been secondary edited in

the Photoshop to make the light much realistic.



Based on this edit I can explore the light and shadow that are created by the

framework and translucent material and so how the effect on the internal and external.

The images show is kind of qualitative imagination I want to create. This study

successful explores the context of the landscape architecture with site and the effect of

light creates on internal and external landscape architecture.
