I approach design from the "what has not been done before" approach ..or the "Devil's Advocate" route...meaning I like to push the envolope
(I am sure you guys can attest to)...I have notice that I tend to Use alot of curves and/or utilize a strong curvilinear design astectic when it comes to a far futuristic design.
And tended to use strong "hard" lines when a design calls to be more industrial or retro in its look....
I also ltake alot of inspiration from the "natural" world (I say natural with quotes, to differenciate from my belief that all things are natural ....Even machines are natural...as they are an evolutionary extention of us...but that's getting a tad off topic...lol) . I look at rocks , trees, animals, parts of machinery etc.. for shapes that I can utilize for concepts...I mean I'll even take a look at a crack in the sidewalk or a stain on a wall/floor and find some insight that I could use.
Its hard to pinpoint where my or most people get their inspiration...But all I say is to not discount your own feelings towards an idea...I mean look at books if you want too, or draw doodles or whatever...the point is to do...not to dwell...If you think about a design too much...your not producing anything...you have to put your ideas on paper or on a computer or model it or anything...but you got to get the concept from the infinite aspect of your mind to the finite aspect of the "real" word . Only then can you really understand the reality of the concept...so you can change and manipulate the idea till it suits your ideal....By doing this, it helps in 2 fold ...first: It allows you to rationalize the design, and "perfect" the concept...and Second: you can have variants that you can make
. Another advantage to having an idea out in the "real" world is that you can begin to create personal refferences that you can call upon when you need it.
All designs should have proportion...the trick is proportion is a relative concept that can only be defined by either references from the "natural" world as in a practical and/or engineering sense , or from the whim of the designer...For example...If you are creating a new race or a new world you are (for all intents and purposes) playing "god" or "mother nature"...and thus you can do what you want...but if you are designing a ship for say...the federation then I would look towards the design aspects of mulitiple races and concepts that have been established, and can be introduced (hope that makes sense).
So to make this post short:
Bottom line...you can get your inspiration from anything or anywhere...from established works or totally obscure sources.
Also...you HAVE to get the ideas down...don't keep them harbored in your head
Lastly...and many who know me know I believe in this: never give up...don't be discouraged if your concepts don't come out the way you envisioned...Or if someone tries to be disway you...keep them(as in don't through them out...as the idea is the most important aspect of design...not the finished pieces ...as the finished pieces can be reproduced at any time...the concept cannot) and Keep on doing
PS: as my sig says "All things end"...I use this to remind me that once an idea is done as a finished piece then it has ended...but it creates room for something new
Hope that helps...
OK Atolm will shout up now
