“GardenCAD” is a landscape designing tool provided
with a less user-friendly interface but a complex 2D drawing
solution which enables advance drawings such as designing
slopes, providing complex symbols and printing the design
in ISO standard scales. A unique feature would be that, it
supports file exporting to Google “SketchUp” to render and
view the garden in a virtual environment [27]. On the other
hand, “Kammb Virtual Landscape Designer” addresses
novice audience to design gardens by providing a critique
system that would guide end users to design on their own
whilst providing simple 2D symbols as used in “Garden
Planner” as well.
In summary, it was found that various 2D based CAD
tools were used for landscape and interior designing, each
having its own strengths to achieve this common goal. The
disadvantage arose mainly due to the limitation of
visualizing the design in 3D as well as the freedom to
include custom made 2D textures and 3D models. Although,
“Autodesk Homestyler” and “Floorplanner” has many
advantages of being online tools, the response time for each
of these would be decreased when the numbers of models or
textures increase. Since many architectural aided CAD tools
are moving towards 3D building simulators [23], the use of
2D tools are gradually decreasing and faced with many
limitations from a client’s perspective. Therefore, useful
features such as virtual walkthroughs [39] and environment
transformation can be considered as drawbacks from the
above findings. It is understood that a 3D view of the garden
as well to support custom made 3D models to minimize
these issues involved would be ideal in a solution as
discussed above.
B. 3D Based Tools and Technologies
This section would analyse 3D based CAD tools that
would not only be limited to landscape designing tools but
rather extensive research on interior designing CAD tools
have also been taken into consideration. These findings are
presented in table 2 below.
Foley stated in [13] that, “A fundamental difficulty in achieving total visual realism is the complexity of the real world. Observe the richness of your environment. There are many surface textures, subtle colour gradations, shadows, reflections, and slight irregularities in the surroundings objects. Think of patterns on wrinkled cloth, the texture of skin, tousled hair, and scuff marks on the floor and chipped pain on the wall. These all combine to ‘real’ visual experience”. From the Get-go, the importance of real visual experience, 3D simulations have increased in recognition [18].Virtual reality (VR) has come a long way since its inception and has received an enormous amount of publicity [23] for its potential to simulate real world environments. With the above in view, such application like Google “SketchUp” and “Unity3D” is biased by this technology and leading in the landscaping industry with many advantages over its features. However, VR is technologically advanced and it supports many features, it’s difficult to bear additional hardware costs since “Unity3D” would require expensive hardware for rendering purposes whilst “VR-CAD System” would require additional hardware to support Virtual Reality. Based on the research, it was also noted that some of the above tools have the flexibility of supporting many 3D models including COLLADA, 3DS popular 3D model file formats which could be beneficial for a novel approach to support these file types since it would give the end user the freedom of importing models from a model warehouse such as “Google Warehouse”. ‘AutoCAD’ is known as the pioneer in architecture designing seawares but the newer versions requires high-end PC specifications and the cost for licensing is unbearable for an individual user. “Sweet Home 3D” is an interior designing tool which has many benefits over “Google SketchUp” whilst both have not addressed important features such as cost estimation and report generation which would benefit an architect or a designer immensely. Thus, in order to further evaluate on the latest technologies used to create virtual environments, a comparison matrix is done as shown in table 3 below.
Different technologies are needed to build different types of virtual environments [5]. With this in mind, as an example, VR environment system is with the use of virtual reality modelling language (VRML) technology was used as a tool to develop collaborative e-leaning environments [26]. In order to develop a better solution, a comparison matrix has been evaluated as shown in table 3 above to identify the most suitable and best approaches in terms of technology. One of the main advantages of “Sandy3D”, “Away3D” and “Papervision3D” over other technologies is the prevention of hardware acceleration so that it addresses end users with minimal PC requirements. Since these 3D engines are flash based, support for desktop and mobile is freely available although a web application approach would require additional work since 3D models should be exported to a web compatible format where some unique information would be lost [22]. However, these technologies are backed with proposer documentation and community support and technologies such as “WebGL” is still new to the industry. Thus, the ideal solution should encompass a FOSS landscape designing framework built using VR technology. The framework should allow the landscape designers to navigate the proposed landscape design in a 3D space at different speeds and scales which is an important interactive feature [14] in terms of 3D environments. However, with the growth of 3D models, it is necessary to have a feature to be able to import 3D models, since they reflect changes over time and the framework should keep the models up to date. Furthermore, useful features such as “chat”, so that a conversation can be done with the client while exploring the design, a warehouse to share and store 3D models from a single destination are yet untapped in most approaches.
