Wire frame C&C (perspective)

[Alynn]

Ok, doing as I usually do, and building a wire frame of the room before I actually create it I came up with this. My main concern isÃ,  the drawers making sure they are in perspective... since they are technically the same size... I've always had issues with things that are supposed to be the same, and makeing them realistically smaller as you get farther from the POV. So anyway, advice would be appreciated.

Thanks.

To make the drawers the same size you just need to make them equally sizen vertically. they do squeeze a little bit on the sides, but keep the sides of the drawers as far from the side of the desk as the others are. That'd give the impression that they are the same size... Here, I draw some lines to indicate what I meant:


Notice the same vertical red line. I reckon it should reach the tops of the upper drawers too in order to male them the same size as the one down... The thinner horizontals lines I drew there just to show the point, though they seem to be in order.

But... I don't understand what you mean, Tuomas. ALL the spaces will get smaller as they get further from the camera. Making some smaller and keeping others the same size is going to look really odd, surely.

[Andail]

Yes, Tuomas, you're simply wrong.

I'm in a hurry right now, so I can't illustrate it.
One way to establish how four drawers would look, would be to draw a cross, where each line ends in a corner of the frame. The perspective middle would be in the intersection of these lines.
To establish the perspective quarters of the box, draw new crosses, etc.

[Kinoko]

Yes, er, I'm going to bed now too so I don't have time but Andail is exactly right, you do it using crosses. Doing a search on google for perspective should pull something up about it.

[Helm]

what you have right now is quite enough, go ahead with rendering.

Alynn,

You could probably save yourself a lot of time by doing a quick mockup using a 3d program and then drawing over it.  That way you wouldn't have to worry about things like perspective, it would just be perfect...and if you spent some time to learn how, you could even render out a separate pass for lighting...draw yoru scene in solid colors and just multiply by the lighting pass

[Snarky]

Right. As Andail said, you draw the diagonals of the rectangle, forming an X. They intersect in the center, allowing you to divide in half, and so on.

And as Helm said, what you have currently is perfectly fine. It's not important to get the perspective precisely correct, as long as it's close enough to look right.

[Tuomas]

I most certainly refuse to be wrong. I didi so many tests and all of them prove in favor of my theory, well, anyway do the x thing

[Andail]

Tuomas, just trust me buddy. In this case, you're wrong.
I don't know what tests you have performed, but either the design of those tests is flawed, or you have misinterpreted the result. I'd like to see them, though, to get an idea of what you're basing this incorrect idea on.

Tuomas, to see the light, please click here.



I used the original distances of the upper drawer (A1, A2 & A3) and connected them by a line (VP1) to the original vanishing point.
Then I chose a second vanishing point (DVP) on the horizon (H), in this case the bottom left corner of the pic, for my diagonals to meet at.
The first diagonal I drew (D1) intersects A2 and A3, from there I went down to the original VP and got VP2 and VP3.
The next diagonal (D2) starts where A3 and VP1 intersect.
So, D2 provides me with the y-coords of the next two horizontal lines.
And after adding those, I get the start of D3, and so on.

I hope my explanation isn't too messy, it's a very simple method after all

[Alynn]

Ok update... Using the X worked perfectly... now I just wonder if the ceiling wall line is too high... but I'll just deal with it for now.

The real fun part will be animating the drawer objects that open... sheesh.

Anyway.... there ya go.

[Andail]

That looks good to me. Hopefully even to Tuomas
Now go on rendering!
