Schematic Rendering Technique

[Phil Read]

Rendering in Revit; raytrace - no radiosity. Subsequently a wireframe *.jpg is exported of the same view.

The two images are overlayed with the hidden line on top. Then the wireframe image is modified to +/-25% transparency.

The final result has a nice sense of lineweight without seeming overly resolved. And the highly transparent underlay also provides a good degree of the internal space/form without being too literal.

All the best -

Phil

Really nice effect Phil !

Thanks for sharing that technique.

Love it ..

Did you set most materials to default first? & if so what was the base colour?

This has tremendous potential ... Do you not think it would be good to be able to select blocks of different materials in one go & then be able to control / set their transparency ? At moment it's time consuming to alter numerous materials individually.

Very nice Phil....almost looks like SketchUp! :shock:


....but didn't you tell us to NEVER use the default accurender sky??? ;-)

Because this is schematics, they've gone light on materials and concentrated on form/space/shadow/light/opacity/transparency. Interesting project; can't go into details - but the client was gracious enough to permit me use the image to illustrate a process.

Yeah - the default sky (life's full of inconsistancies). In this case, it actually seems to work. Who'd a thunk. :) Anything more dramatic/realistic seemed to draw attention away from the proposed forms.

I've done sequential renderings where major portions of a project (think: worksets) are rendered separately then used as overlays in a PowerPoint (or Keynote ;) ) sequence. Suppose you could override a worksets visibility with a "transparency" factor in shaded or rendered views? Might be interesting. But this process has some interesting benifits with regard to how line/forms/space are schematically resolved.

Totally agree that it works well in this image! just giving you a hard time! Now where's that red porche?

Hi Phil,

Very Nice indeed! One question though. How do you make a wireframe camera view transparent in Revit?

Thanks in advance

The wireframe IS transparent, and he just overlaid in Photoshop. Sounds like he has a Photoshop layer for each rendered workset since he rendered each workset individually so that the building appears more transparent than it is.

Hi,
So, if I understand it correctly, changing the transparency was done in PhotoShop. Too bad since I don't have that.
Very nice anyway!

Very nice indeed phil and thanks for sharing the technique with us :)

SCShell, if you don't have photoshop, try this :

It's a freeware photoshop clone, yep, absolutely free, and act almost like photoshop.
