Re: Basic 101: Class 3 - Drawing Cubic Objects

First I attempted the dice with 3 point perspective, "birds' eye" view. I did not like the look as they appeared very skewed; I tried several different angles but didn't care for the appearance. (I have attached one of the sketches). Then I drew them using two VPs for each die. I also drew the brick shelf with the clock. I couldn't find the PDF link for this lesson so I had a hard time with the small picture to make out the details of the clock and candle. I thought the candle might be round inside at the bottom but I just drew it more cube-shaped. I thought about drawing something from real life but I had already started on the shelf. Looking forward to critique, thanks!

.

You know arnould I downloaded Gimp and the tutorial but I have absolutely no idea of which tool would provide me assistance with drawing the VPs on top of my file?

Re: Basic 101: Class 3 - Drawing Cubic Objects

DivotDiva - Very well done . I like your illustrative style - outlines with a suggestion of shading.

3PP is a camera distortion anyway. Up to the 1960's professional photographers carefully avoided it - with special technical means on their expensive cameras. The reason it looked very skewed, at least for the example you uploaded, is that the two vp's on the EL are too close together. You would have an unpleasant effect in 2PP as well. Additionally in 3PP the 3td VP should be central.

OK, in telegram style:
Image -> Canvas Size: to make room
[if necessary to have a good overview, down size the image first (Image -> Scale Image)]
Layer -> New Layer (fill type: Transparency)
Tools -> Pencil - or Brush choose appropriate size and color
Draw straight lines: click on starting point, Shift-click on end point

The reason for working on a separate layer is that you can erase and retry as much as you like. The original scan is not disturbed.

You did very well in this class, please move on to class 4 .

thanks, I will try that in GIMP. I figured it must be a layer but I didn't know when to start. and Ah yes I forgot that the 3rd point on 3PP should be in the middle of the drawing. No wonder I didn't like it. I recall having to do several 3PP exercises in school many years ago, drawing high rise buildings.

As for my "style" ...thanks, -- now I know what to call it! Hoping to improve!

Re: Basic 101: Class 3 - Drawing Cubic Objects

sapf -
Good job .
When copying 2D works, it is important to use your knowledge of the real world to guide your interpretation. That is why it is much better for your development to draw from real life. The "antique" silo: we see two walls and that one corner. The right wall clearly turns away from us (right edge further away), so, because the corner is 90 ° - we may safely assume - the left wall turns away from us as well (left edge further away), NOT towards us. As you drew it (red VL's). And how a builder could construct the corner highlighted in blue, is a complete riddle for me .



Please move on to class 4 .

Re: Basic 101: Class 3 - Drawing Cubic Objects

Hi,

Here is a grain elevator I found a picture of online. I think I corrected all the perspective errors from the photo.





Thanks!
Matt

Re: Basic 101: Class 3 - Drawing Cubic Objects

This is very well done, Matt .
One point, outside the scope of this class, but anyway:
the letters seem to lean forward . In traditional perspective, particularly in architectural drawings, vertical lines are kept strictly vertical. There is a "trick" to apply perspective deformation to a text - well, as a matter of fact, any deformation to any form. It is copying by modified gridding, normal source grid, distorted target grid.



You've no problems with the subject of this class, please move on to class 4 .

Thanks! I wasn't originally planning on drawing the letters and then added them at the last minute, I'm not too happy with how they turned out. Thanks for the trick, it will definitely come in handy in the future.

Here's another one of a fire lookout tower that I also drew for the lesson:

Re: Basic 101: Class 3 - Drawing Cubic Objects

I did the first lot of cubes awhile ago then I did the dice two to three days ago, I hope they are ok.
