Hey all,

I hope that this question is an ok one to ask. I am trying to draw something from the perspective of looking up at it. (ie: a rectagle looking from the base to the top of it.)

The prob that I have is figuring out where to have the vanishing points. I know that you need more than one in this instance but not sure where abouts to get the angle.

If anyone could help or point me to a web link or something that would be awesome thankyou.

I don't get the example:

Sorry for the confusing example. What I was meaning like when you are looking at a tall building. You are at the base of the building and looking up to the sky.

Thanks for the link Smile

If I were going to draw a tall building from my viewpoint standing on the ground and looking up to the top of the building, I'd treat it pretty much the same as if I were drawing a long straight road ahead of me.

The vanishing point would be in the sky .. way up in the sky.

Depending on how close I stood to the building, the vanishing point would be higher (when I'm closer to the building) and lower the more I move away from the building.

Just as if I were drawing a long straight road. If I were to lie down on the road and lift my head to look toward the end of the road, the vanishing point would appear higher to me than if I stood up and looked down the road when the horizon line would then be lower than eye level.

Does that make sense to anyone?

Just imagine both you and the tall building being rotated 90 degrees to lie flat on the ground, then figure out the vanishing point from that viewpoint.

Now does it make sense to anyone?

Hmmmm.....

Lymel:
2 point perspective might work

but I guess now that it's 3 point perspective that you should look into.

It's not easy to find examples for 3 point perspective. In this example the viewer's eyes are higher than the buildings. You'd need a VP above the horizon I guess if that's what you meant.

Cool that 3 point is awesome....Thanks for the help.

Now time to make some perspective drawings....er....when I get home from work Neutral

If you have access to any 3d software, it is easy to set up a simple block model to help visualize your perspective. You can use a printed rendering as an underlay for your drawing.

or if it's simple enough... just find an object that looks similar (IE a cerial box from the side of it) and it will save you about 2 minutes Razz

... or if it's right in front of you...

But it's just for simple things... If you are going to do multiple buildings... use legos j/k. 3d is almost always the way to go, that is if you have a program for it.
