I’m a very happy that this helped so much. Learning perspective from books can be challenging because it’s a hard discipline to explain without moving images. Thanks for supporting the channel!
thank you so much for these videos. i understood a lot of these concepts already but the way that you animated them just helped me understand it even better. I used to get confused looking at drawings with the horizon, station point. Now I understand why the vanishing points move so much when you rotate and how to place the viewpoints. One thing I've learned is that the distance from the Horizon to the Station Point is the distance from the floor to horizon, so knowing that your "camera" is 6 feet from the floor might be useful
Thanks. It was the final tutorial what I needed to really understand how the standing point means and works! I love how you explained that what the distance between cvp and so mean! I read two books about perspective but your video really makes it much more easy to understand!
Thank you! I have gone through many perspective books in my time too, and it is difficult to catch some of these concepts in them. Glad the video helped so much!
That’s good to hear! I try to make them simple but full of information, so it’s great to know that you are able to revisit them and still get something out of it :)
@@DrawshStudio yeah man you're crushing it! One of things I'm struggling with currently is connecting my knowledge of formal perspective and intuitive estimation. Do you have any resources on perspective short hand or "perspective on the go" ? That would immensely helpful 🙂
That’s a great question. Scott Robertson’s “how to draw book” is very technical but does talk a bit about free handing things and correcting with tools. Marcos Mateu-Mestre Framed ink has a unique way to look at perspective. But ultimately, practice with tools a bunch, and then try without, back and forth working on controlling the straightness of your lines and imagining you vps. Alternating practice will inform both approaches. :). Something I can address ina future video tho, thanks for the idea!
This is the clearest and best explanation I’ve come across. One question - why is it okay to rotate the station point to CVP line onto the picture plane? I get that it works but it seems like magic!
Thank you! Glad it was so helpful to you :) it does seem like magic! The side view helps understand why it works. The station is where the viewer who we base the perspective view on is standing, their distance from the objects in the scene. In a side view the horizontal distance would be the same as the vertical distance, and since the cvp represents where the point directly in front of the viewer, then that same vertical distance from that point would be where we get the station point. I hope that makes sense!
Thanks for all these vids! Quick question: at 1:20 you place the CVP slightly to the left of center. Although this is technically possible, what would the logic of doing that be? Because it means that you'll have uneven distortion on the left and right of your frame (not symetrical). I guess you could use it as an effect? I'm really a noob so it could be i'm misunderstanding something here, but people almost always show the cone of vision as being centered in the picture frame, although i guess it doesn't need to be.
Correct, the center vision point can be put anywhere in the picture plane to change the composition. Since you are new, I suggest watching my perspective playlist in order, each video builds on the e next. Many of your questions are answered in my other videos.
Great vids, I currently teaching digital painting, and I recommend your vids to everyone for fundamentals - you've managed to explain the most clearly and succinctly on these topics I've seen so far. Thank you so much!!
Thanks for sharing the videos! That makes a big difference in helping the channel grow so I can make more videos. Glad you are enjoying the material :)
Ahhh. I'm learning to draw and this was a big missing piece for me. I was having a hard time rotating objects in my 1-poiny perspective scene. This is going to go a long way for me, thank you!
hi! thank you for your great and quality videos. i'm not sure if you can see my comment since it's old video but few questions. I understand the video until 2:00 where right angle is used to set vanishing point and i don't get why you should use right angle. is it because you're drawing box shaped object or is it something to do with cone of vision in your next video? or am i just missing some fundamental concept here.
First off, thank you for your valuable work. These videos are top quality. I have one question. Why does the lines crossing the stationpoint create vanishing points? What I know is that all parallel lines converge to unique vanishing points. But station point is below the picture plane! How can lines extended from the bottom of the picture plane affect the picture plane? In other words, what justifies the placement of station point below the picture plane? Sorry for weird phrasing of the question.
The station point is the distance the “viewer” is from the picture plane. Since we are viewing the world through their eyes their position changes everything. Like the video shows, the distance away in depth from picture plane can be represented also as a vertical measurement.
Excellent thanks. At 2.02 you say the vanishing points should be along lines that are at 90 degrees to each other, which pivot on the station point. However at 3.45 you place the vanishing points on the top side of the 'square ruler', not on the bottom side of the ruler which pivoted on the station point. Is that ok because the resulting vanishing points are closer together than they would have been had you placed them on the bottom side of the 'square ruler' which pivoted on the station point.
Good catch, I should have put the points on the edge of the ruler that lead to the station point. This would have been especially important in a scene with multiple objects to keep it consistent.
I have a video on camera lenses planned for the future, so keep checking back. As far as the vps, I don’t know of any circumstances where they would be different than 90 degrees. The camera lens simply changes the distance the viewer is from the picture plane. In short, a wide angle lense is as though the sp is close to the pp. a telephoto/zoom lens is as though the sp is far from the pp. Hope that makes sense, thanks for the comment.
Thanks, this is the best explanation i've seen and needs more views. But i still have one burning question: if we're working with 3 point perspective, how do we incorporate the station point which rotating objects? I can't find any tutorials that show a station point in a 3 point perspective scene.
Thank you! That’s a good question, I have a lecture on this I present in my classes which will eventually become a video when I am able to produce long videos again. 3 point creates some complex issues that take a little explaining to figure out. Thanks for supporting the channel :)
When you are placing the station point with a 90° angle down and they placing a square, and rotating it, does it matter how much you rotate it? For example I don’t junk yours was perfect 45° in either direction I think yours was slightly skewed
If I understand your question, It doesn’t matter how much you rotate the square to find the vanishing points. If you have multiple objects that are at different angles to the viewer, their vanishing points would come from several different angled “squares”.
Thank you so much for this really clear video. You are much better at explaining perspective than my teacher is, lol. Genuine question that might be totally stupid. Couldn't the same result be achieved by simply having the same distance between each pair of vanishing points? (For example, the distance between VPa1 and VPa2 being the same as the distance between VPb1 and VPb2?)
Good question but the answer is actually no. If you pause the video and measure the distance between the A’s and the B’s they aren’t the same. This is because as the right angle tips through the vanishing point it is hitting the horizon at different angles making the distance between each pair different than other pairs.
Hi man, i'm trying to understand the station point and cone of vision and it seems i probably having a hard time understanding the picture plane too. I would love if you could enlight me on those 3. My understanding is that if you drew on a physical viewfinder whats behind you'll get a perfect representation of the image behind it so that mean that if you just place the viewfinder flat on a table in front of you the viewfinder is then the equivalent of the drawing you would have made on a piece of paper so my questions are: -1. Is the picture plane a mental/imaginary ( in your head ) equivalent or same thing as a physical viewfinder ? -2. And if so does it mean that to be able to draw you should have the viewfinder built in your head "picture plane " and frame your image into it ? -3. And if so how do you feet your image into it ? Example: a 160cm tv on a 21 by 29 piece of paper ? Sighting ? Thanks
Essentially yes, the picture plane is equivalent to your view finder. The first 45 seconds of this video illustrate the concept of the imagined viewer looking through a picture plane, and the station point being the distance they are from that plane. However, as illustrated later, the picture plane is somewhat arbitrary in that you can make it any size or position related to the viewer given it remains perpendicular to them. You must also keep in mind that the cone of vision shows the limit of the viewers sight without distortion, which is usually a small fraction of the picture plane. Lastly in regards to your question of scale, I have several other videos that discuss different ways to create and account for scale like the 1 and two point grids, and measuring. Once you create your sense of scale, you choose the real time units it represents and draw accordingly. Hope that helps!
1:57 Can we change this angle to create different angles in 3D space? For example, if I wanted two edges to meet at a 60-degree angle (in 3D), would I choose my vanishing points to form a 60-degree angle with the station point as well?
I’m not sure, In theory that may work, however it may just appear like the form is distorted in space like the image in the video where there are vanishing points that don’t match the station point. You may need to apply a different approach like constructing an ellipse on the ground plane so you track degrees in the correct perspective?
Thank you very much. But there is a problem when I draw a 3-point perspective, when I rotate the x axis of the box (side view), the z axis will be tilted. At that time, the station point will be moved (I checked it with 3D software) and I don't know how to calculate the exact distance it moved. Do you know how to calculate it?
Yes but that is a complex topic that can’t be easily explained in a RU-vid comment. When transitioning into 3 point perspective there are different things we need to account for to get correct station points.
Thank you, glad you like the video :). @2:00 in I talk about creating the station point. You decide where it is, you’ll just need some long rulers and a right angle to place it on your page.
You may start at the beginning of my playlist to help you build into your skills, unfortunately, perspective is a dense topic to wrap your minds around.
So I can place the CVP just whereever I want? And how do I know where the SP sits? I or whoever looks at my drawing could just move their eyes closer or farther away, right? And if my SP is OUTSIDE my page, how do I know where it is, like how do I place it then? Sorry if these are obvious questions
Let me see if I can answer all this succinctly: You place the cvp wherever you like. The SP will be directly below as far down as you want. This choice will change the look of the perspective. Anyone can look at your paper at any angle or distance and it doesn’t change. The “viewer” is the theoretical person who’s eyes we are “looking through” The SP will probably be off the page for “normal” looking perspective. Work on a large surface or digital file and place it below your paper (picture plane). Hope that helps. Good luck with it!
Nice informative video, but the angle subtended by the vanishing points to the station point is not 90 degrees in the end demo. Could cross-check at 3:44. Your students may end up doing wrongly 🫣😉 You are explaining and doing good, our mentor shall complete the video with perfection.
Thank you. But in the end demo I am using a 90 degree ruler to plot my two vanishing points. I rotate that 90 degree angle from the station point to plot a set of vanishing points. I am not sure why you claim this isn’t a 90 angle.
@@DrawshStudio Dear, U kept SP outside center corner of the ruler and marked VP using inner edges of the legs of the ruler. Therefore it can't be 90 degree angle subtended by the VPs at the SP.🙂 Otherwise you are doing great work, explaining with good animation methods. It becomes self explanatory most of the times.👌🏼
