Re: Basic 101: Class 3 - Drawing Cubic Objects

Tim - Nice drawing, good attempt at shading .
The right dice has the correct proportions, but look again at the left dice. The perspective is off, and observe how it does not represent a cube, the height is out of proportion.

Re: Basic 101: Class 3 - Drawing Cubic Objects

here's the redraw of the dice. Guess I did have to do them twice.

Re: Basic 101: Class 3 - Drawing Cubic Objects

I was going to add something to my last post but had a guest and my 60 min. timed out. I'm using this corel painters essentials 4 software, and I opened my scanned image using it, rotated the image and cropped it. why did it revert to the original orientation? I have GIMP on my computer, but haven't had time to figure it out. The manual is very lengthly and I really don't want to print it out. does anyone know of any good tutorials on GIMP?

Re: Basic 101: Class 3 - Drawing Cubic Objects

Good job, Tim .
Now it is correct for the subject matter of this class. But in reality the VP's of the left dice will lie further apart. The nearest corner of a cube can never - NEVER - be sharper than 90°. When you look completely down on it, it is 90°.



I've no experience with Painter, it could be that you have to do it the other way round, first cropping.
GIMP is very powerful, hence a large documentation. But the simple operations - cropping, scaling, rotating, straight lines, improving the contrast - are rather obvious if you have some experience with other graphic software. There is a very good online handbook.

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

Re: Basic 101: Class 3 - Drawing Cubic Objects

Hi,

My assignments:







I will be happy to hear your comments. I tried to make the second dice look like as if it was in the air but now when I look at it, I think it looks like lying on a flat surface and the perspective seems distorted. M.

P.S. I did not find it but maybe there is an option to correct spelling before postig a message? It would be very helpful for non-native speakers.

Re: Basic 101: Class 3 - Drawing Cubic Objects

muikku -
Often my comments are that class 3 is in a sense the second class on perspective. So it would have been wise to wait for the remarks on the class 2 assignments. You made exactly the same errors as in the previous class. So I'd advice to finish class 2 first, and then revisit this class.

The spelling checker is enabled by default as far as I know. But you'll have to correct the errors yourself. Hint: enter the word (in a separate browser tab) in Google: more often than not you will see the correct spelling.

Re: Basic 101: Class 3 - Drawing Cubic Objects

Hello it's me again. Um, I have been at it with my last project and got 4 objects but I seem to keep making them bigger than they are in real life so it's way out of proportion. Maybe I should go back to class 2 ? I just can't draw what I see. Also I can't get them at the exact angles as they are as well.

Catherine - Nice to see you again.

I don't think I get it. In many many drawings, paintings, photos... the sizes of the objects are different than in real life .

I looked up your assignments in class 2. I think you understand the principles. The problem is to apply them on new work. That means diligent attention, much practice, checking and rechecking (with vanishing lines, not just by sight!)
I don't think going back would help much.

Well, if you can see that it is wrong, nothing is lost. You can try and correct it. If still wrong, correct again, and again, until you think it is right .
When people do not see that it is wrong, that is the real problem.
Keep focused .

Re: Basic 101: Class 3 - Drawing Cubic Objects

Hi!

I've made two of the assignments but I'm not happy whith the result. I think when I correct the perspective, the drawing gets even more different than the picture.

I've uploaded the three draws of the dices I made (sketch, perspective corrected and final) to check if I'm doing the process right. To find the perspective points, I try to establish the eye level, and then extend the line I think is more accurate to the reference to find one vanishing point. The same for the other point.

The first photo

Dices sketch

Dices perspective correction

Dices final


Thanks a lot!

pixel blender -
Good job . The problem with the clock is not one of perspective, the perspective is basically correct. The issue are the proportions: the head is too big in comparison with the foot. Also, it is leaning back.
The dice is very well done . One remark, this corner is too sharp if you want to draw realistically. The nearest/lowest corner - if square in real life - can never be sharper than 90 ° in the drawing. The common error of putting the VP's too close together.
