How to create a side view from a floor plan

[jester]

I have the following problem:

There is this floor plan of a castle of which I want to draw different views (bird's perspective, side view, frog perspective etc.)

http://www.jester.de/gallery/sketch/karte-alomgil.jpg

That castle stands on a hill, the hightest part being where the two keeps are (in the Königsburg, No.s 1 and 2). I have no idea how to start. Were it situated on a flat platform I'd try Loomis instructions. I'm sort of lost and already think of building it with paper maché.

Anyone who can help me?

:confused:

Hi Jester,

if you want an easy help, vecorize the floorplan and put it in a simple 3D-program. This is quite easy - I can show you next time, when you´re visiting me. Even something as simple as Adobe Dimensions can do the job ...

Cheers

That's really nice of you, Fipse, I sure will make use of your kind offer.

However, is there anyone who can explain how to do it "the traditional way", i.e. on paper with perspective knowledge?!?

:p

These should help...

Take a look at pages 44-47 http://www.gameartworks.com/LoomisBooks/successful/page_02.htm keep in mind this is only one technique.

Here is the main link http://www.fineart.sk/anat.htm

Andrew Loomis, great stuff.

there's a way to drop floorplans into perspective, but to do it right you need to have an elevation (side view) it is you want to draw. You draw a line near the bottom of your page (ground line) Then you draw a horizon line where ever you want it with respect from the ground line. above the horizon and quite near the top you draw a third line representing the picture plane. Set up your plan (floor plan) view as it would appear over the line of the picture plane (the plane of sight for the vieweres pov). Plot out your vanishing point on the horizon line and then drop two stationary points downf from the pp (picture plane) and hl (horizon line). Make sure they are both the same distance form each. now draw lines form points that the plan view intersects the pp straight down to the gl (ground line). Then draw lines form points of intersection that do not intersect the pp from the plan view to the first sp (stationary point). Where these lines hit the pp draw lines to the gl. Now set up your elevation on the very right or left with the gl lined up with the floor of the elevation. draw lines of wall and object heights horizontally across the page. This will form the correct intersection points of hieghts and widths in perspective. From this point you should be able to guess how to complete the rest if you're at all familiar with how perspective works.

hope all that helped (yikes, that was a mouth full)

you are going to need to make a few elevation drawing as well.

easiest way out would be to make grids for your plan and elevation drawings and then make a perspective grid to draw them on top of...

ChadTHX1138, Wilson, seb, thank you all for your help. It seems that there is no easy way or shortcut so I have to try what you described.

Or is there anybody out there who knows an easier way?

Well i did see a trick once where you would place the floorplan in a 2-point perspective (assuming the floor of the castle is flat) and then place a third point way down so you can get a three point perspective of the building. Use the third point to make your vertical orthogonals. You still need to know how tall stuff is going to be though, that information is not in the floorplan so it can't be tricked out of it. A photo would probably do it. The 3D program trick is also worthwile.

The way I've learned to do this is similar to Erik's way. I got this in a book somewhere, written especially for technical illustration (making engines and so on, much maths, all perspective) , and when I find it I could explain it in a PM perhaps, or mail some pages (swedish text BTW).
Youl'll still need to know all heights, as Erik said.
And that is absolutely no shortcuts in this method ;). It'll take time.

[jester]

gallon, thanks for the offer. I'll try by the descriptions I got (and the relevant Loomis pages). If I don't get anywhere, it'd be great if you could e-mail me those pages. I have a friend who studied Swedish (and has translated most of Maria Lang's novels into German, just for fun!) - she'll certainly help me.

It will take a few days till I find the time to try out what I've learned here - but be sure that I will post my results. Thanks to everyone!

I have gone an intensive weeks worth course of this stuff. Made my brain even wrinklier! :p
Theese pics (from ChadTHX1138s linktips) do the "trick"
http://www.gameartworks.com/LoomisBooks/successful/46.jpg and http://www.gameartworks.com/LoomisBooks/successful/47.jpg

Observe that U need to know the scale - at lest the hight of a human in comparison (tom get the "eyeheight", and the different heights of the towers, walls, buildings and so on (to meassure them andget them right on the in the projected image).

On the course I went, we made a typical little Swedish cottage complete with a flagpole. To learn to do that (well, learn and learn, Ive already forgotten most o the stuff...) took 3-4 days. :eek:

Sadly, I cant show U the pics, because although the cottage was only about 8 centimeters wide on the technical drawing, when converted above the imageplane, it grows (in my case to about 15 centimeters) which in turn needs a paper almost 2 METERS wide! :eek:

Some good instruments for the job includes: different color pens (to differ all theese lines), large rulers, at least 2 large triangles (4 is even better - of different types), tape, needles, string, a very large table, a board to nail the papers too, "bakery type paper" (the one U can see through - preferably on a large roll), big papers. And of course lotsa coffee and fresh air!! :D

Good luck!!! :chug:

Thanks for links and warnings ;) Johannes, I hopefully get to try this tomorrow.
