Rendering Tip - Use 2pt Perspectives
-
Tip of the Week - Use 2 Pt Perspective for vertical alignment
Due to the type of default perspective that SketchUp use, sometimes buildings can become distorted. Using two point perspective can correct these types of distortions.Two point perspective, sometimes called ‘2D’ in SketchUp, will keep the vertical lines of your model parallel to each other.
If your rendering software supports 2 pt perspective, use it for better renderings when ever you are looking up or down on models with vertical lines.

xrok1 - I consider this another of your spam/abuse posts.
I am going to recoomend (again), that you be banned from this forum if you are going to stick in posts like this which really have nothing to add the threads you are trying to sabotage.

What's wrong with Xrok1's postings?
Al, you can't expect your render solution to be the only one allowed to be mentioned on this forum....I think Podium Render can do 2point perspectives as well.

What's wrong with his posting.
There are more than 30 rendering engines which work with SketchUp. If every time any one mentions anything about rendering, all 30 of us (or even just 15 of us), add otherwise meaningless posts recommending our products I think it will take away for the value and integrity of the forum as a whole.
Other may disagree. But I feel it is up to the moderators of the forum to set the tome for what they consider acceptable.
Here is xroks other abuse/spam post.

the question is... why would you want IDX if you have Twilight anyway?

Vray can't do 2Point perspectives (unfortunately).
I am not sure about the latest Skindigo and Maxwell... -

He has as much right to ventilate his opinion as you do.
It was a humurous comment he made and he wasn't abusive in his language.If you are referring to this post:

I think it was not appropriate for a thread which was reporting a problem users of one rendering package were having when they installed another package. the rest of thread was used, quite successfully to diagnose and repair the problem.
I found it quite out of place.

I suspect most of the renderers can handle 2 Pt perspective.
That is the point of the Rendering Tip - to remind people - especially people new to rendering - to use it. Both in SketchUp and with external renderers.

We have sorted that out with "xrok1" in PM's

Rocky, p,lease chill out. Everything and everybody has its own place and time. Let Al play around and see what he really means.

The workaround for renderers that don't recognize 2pt perspective is to make sure that your camera is pointed in a direction parallel to the ground plane. You can do this within sketchup by making two vertical lines of the same height (say 5'5" for example), picking the Position Camera button from the toolbar, clicking the top of one of the lines to pick your camera location and dragging your mouse to the top of the other line before letting go of the mouse button to set the direction you want your camera to face.
I use this within Maxwell Render (which doesn't do 2-pt perspectives) with almost all of my arch-viz work. Maxwell also has a Shift Lens parameter which essentially shifts your lens up or down within that frame of reference as doing a 2pt at eye level will often cut off the top of your building and almost always show too much foreground. It shifts the lens up to correct that (many real architectural photographers use a shift/tilt lens for the same purpose)

As you say. this is kind of like the 2 Pt perspective cameras which kept the lens parallel to the view, but shifted the image to look up without distorting the vertical lines.
They would never have invented these cameras if the 2Pt Perspective image was not important.

Al, not to sound too sensitive, but since you've twice repeated this quote here, I thought I would note that one reason "it was out of place" was that IDX didn't have the problem (he was unfamiliar with IDX), but it was iRender that had the conflict with Twilight. (Anyway... IDX handles 2-point perspective as well.)

i use all your tips with the $99 Twilight renderer from http://www.Twilightrender.com . thanks for the tips, they're very easy to implement with Twilights easy interface and Twilight always gives me excellent results will very little effort. You should check it out at http://www.Twilightrender.com .
PS, did i mention they're awsome forum and technical support?
-
that's what i get for thanking you for your tips?
BTW, that emoticon is from the http://www.Twilightrender.com forum where i get great tips and great support. Check it out!

thanks for the tip Brodie, if you check out the list of upcoming features for TW:

2 - All new Twilight "Position Scene's View Tool" ,
- allows you to previsualize the precise window showing your precise rendering.
- allows you to click any point in your view as your new focal point for driving the DOF focal point.
- allows you to orbit your view around a selected point in your scene... instead of around some nebulous 'point'
it seems that they're fixing the 2pt. problem as we speak and adding some awsome new camera tools too!!
BTW, i've edited my previous posts, it seems that i put twilight.com instead of http://www.twilightrender.com sorry if i misguided anyone to some silly vampire site.
