Re: Basic 101: Class 3 - Drawing Cubic Objects

Arnoud - Here are a couple drawings I did for Class 3 on cubic forms. They were way more challenging than I expected with so many cubes combined in one image! I had a bit of trouble with my roof lines working themselves back to horizontal even when I told them to slope to the VP.Also, making the windows in the same perspective and making them look realistic. I feel the wing to the right on the house still is not quite right, the perspective I mean. In the photo of the house the far right wall does not look vertical, though it does on my paper. (The house was not falling down!). Same thing with the far side walls of the barns. They were vertical on the paper, really! Also had some struggle figuring out how to do sloped roofs in perspective but I hope solved that.



I have a question about the method though. Reading de Reyna's book on this lesson he said "do not erase!!" when you are trying to find the right perspective lines. Can you explain why not? My attempts get so messy I can't tell which line I have decided upon. Also, I think I tend to go too quickly to detail and then have to backtrack when i suddenly notice something not right and then have to trace the details.... impatience!!
Any tips?

All input appreciated.
Thanks, Barb

Remember the very first principle of perspective "Further away looks smaller" ?
Humans tend to compensate, a camera cannot. Take care to point the camera perpendicular to the paper.
Best practice is to use a tripod and the self timer. To get it completely correct, put a little mirror flat against the drawing. If the camera "sees" itself in the mirror, it is correctly aligned.


This is when I straightened the edges of the paper with the "perspective tool" in the drawing software:

That is a general principle when sketching. If you erase the wrong line, you're back at square one. The wrong lines will in fact guide you in finding the correct form. The knack is to start with very faint lines, strengthening only very gradually.
And yes, practice makes perfect .

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

Re: Basic 101: Class 3 - Drawing Cubic Objects

Here is the sketch I used as inspiration for this assignment:


I messed around for a while shading and blending and had a good time. At the end I decided I would try to draw some clouds in the sky, though the composition and execution were both poor.

To my (apparently untrained) eye, the perspective looked good until l I drew in the perspective lines !

I find it very difficult to make the lines converge all at the same point, especially when there are multiple walls that need to be kept in proportion. For a more serious piece I guess it would be almost necessary to use tracing paper and transfer the corrected rough image onto a clean sheet. Can anyone provide a good link for how this is done? Everything I see comes up with a technique that seems different from what is described in the class notes. If I just put charcoal on the backside of a tracing paper that has my image drawn on it, would that not get charcoal smudges all over the new piece of paper? I have absolutely no experience with these materials




I suppose it may have been best to go with a photo in correct proportion rather than some out of proportion sketch for this assignment. I am going to give the dice a try

Re: Basic 101: Class 3 - Drawing Cubic Objects

Alex - Nicely done .

I cannot see when you checked the perspective, but it is strongly recommended to do it on the basic skeleton, before adding details and rendering.
I like your rendering very much .

Transferring to the "good paper" can be done in many ways. A concise explanation is in the class on Colored Pencils.
An intermediate "tracing paper" is only needed if you want to preserve the "original", e.g. from a book. I wouldn't use charcoal, but the softest graphite pencil, and applying it only under the lines to be transferred, not on the whole page. But very often the good paper is not so opaque that you cannot trace on it directly, on a lighttable. Nothing expensive, it can be improvised easily, as here:



Or even simply a PC monitor, tilted for comfort, displaying a white page.

Re: Basic 101: Class 3 - Drawing Cubic Objects

Thanks for the advice and the link Arnoud!

I just finished with the die and was a little sad to see some errors in the completed project. I checked everything after the initial guiding lines were down. I guess I messed some lines up while I was shading. The two closest edges of the dice converge way too soon. Also the lines going backwards on the top of the right die somehow went from converging in the skeleton to diverging in the final product. I thought I was being careful too!

I didn't really notice how badly I mangled the proportions of the top of the right dice while shading. Now my eye is just stuck on it whenever I look at this picture, I see nothing else; it's funny how that works

Here it is:

Re: Basic 101: Class 3 - Drawing Cubic Objects

Good job, Alex .
Good for you to see the shortcomings, I have nothing to add .
Yes, we all have the tendency to start freewheeling when busy in a repetitive job like rendering ("shading"). It is a general advice to stop regularly, and take some distance - literally and figuratively - to observe where you are going.
You did very well, please move on to class 4 .
