One of the library parts is a picture which allows you to import images.
Does anyone know how this could be angled ? I would like to lean the picture back 15 degrees.
Thanks

SEARCH GDL OBJECT DEPOSITORY FOR "PARAPICTURE"

Thanks Dwight.
Where would the GDL object directory be ?

Returning to the Archicad Forum Index, you'll find it near the bottom of the list.

Look under the General folder....

Thanks Dwight.
By the way I have just bought your Lightworks book will I need to get a supplement for Archicad 11 ?
Also thinking about getting Cinema 4D - could you identify the advantages - is there more polish ?

Register your book. See page 3.

Supplement to 11 will be only about three pages long.
Addresses newly implemented displacement shaders...... not earth shaking changes. You can wait. Get 10 supplement instead. Register.

Sort of busy with Deep Ellum Gateway Presentation this week.

Perhaps sometime in July......

Cinema 4D fun but complex. Professional quality with almost all of the features you could want. Even controls sound volume from placed microphones in an animation. Not that you'll ever need it.
Some commitment to new terminology and technique required.ie: To me "caustic" was soda. But "No!" It is a description of light decay on a diffuse surface. I think.

Complex light/material interaction requires lots of experimentation for superior result.

I believe that the only thing you are missing in Cinema 4D is the treeswaveinthewind feature of Electricimage.

Dwight,
We're designing a gallery with glass cases with the lighting externally and using the parapicture objects you kindly told us about within.
We've found two things :
1 The glass won't let light through to light the object beyond
2 The parapicture object itself seems to be transparent
I feel sure you'll have an explanation of this but we can't understand it - the glass is on a fully transparent setting.
Generally we're trying to create an atmospheric gallery with low ambient and spotted highlights - do you have any pearls of wisdom ?

Hi Dwight,
Appreciate your help
Have added an illustrative images as follows.
Spot in Case shows the effect of light on the subject but also the transparency of the parapicture. I couldn't get the same light to illuminate the subject from the other side of the glass.
In the event it may be that internal case lights would be most appropriate - they might use fibre-optics so I might pursue this aspect but still would like to understand the nature of spots and glass transparency. BTW have used the 'spotlight general source' and library spot without effect.
In terms of the general gallery I intend to make the stone less shiny but would also like low general light levels with punches of light - at the moment its totally flat and grey - a few hints would be most appreciated.
Could email you further images if this would clarify
Rgds & Thanks

Nice composition - interesting geometry.

The parapicture is not transparent - it just doesn't seem to cast a shadow. It's lack of three dimensions might have something to do with that.
How would you fix the situation? Hmmmm? Like a piece of black card backing the parapicture or something?

I light my scenes as a photographer would, only using architectural light for props - at low levels that don't affect the overall scene illumination.

You are a fool to try and light this display using Archicad lights as if they were real.

For instance: the light cone. The dialog box leads us to believe that it should be a point light source, but it becomes scalding and harsh this way. If you exaggerate the source diameter it becomes an excellent room illuminator while retaining soft shadows and directionality.

I shall follow the guidance in your book but does, or should, the glass block the light ? Are my settings wrong ?

Does the light have "Cast shadows" turned on?

And why does the top edge of the light cone get chopped off where the picture isn't (on the wall behind)? Is something else doing that?

Hi S2art
Yes it is. I don't fully understand the consequences of 'by lamp settings' either.
The top edge is also cut off by a piece of glass. The paintings are carried by a frame that slopes back at 75 degrees with a square window. You can nearly see it in the other painting seen frontally - a sloping back piece of glass with a vertical piece to the right hand side.

Still confused ...
Is it possible for light source light to go through glass.
We don't seem to manage to do this.
