I have a digital terrain model (DTM) and an orthophoto. After draping the orthophoto onto the DTM the colors of the image look quite different from the original, with lower contrast. Now I would like to create a 3D pdf, but in the pdf the draped image looks much darker; not satisfying at all.
Is there a way to keep the colors of the original image, so the 3D pdf looks satisfying?
Hi Markus,There are a few settings that you could try in the “Light Manager” dialog box:* Turn on “Ambient” & “Flashbulb”. Experiment with the values but you shouldn’t need to go too high as it will over expose your scene.* In the “Solar > Details” tab, set the cloudiness to about “80”.In the “Print” dialog box:* Got to “Settings > 3D Plotting” and set “Lighting Mode” to “Headlamp”* I also like to set “Display Mode” to “Solid Outline”If you are using Adobe Acrobat Reader DC on a computer with Nvidia graphics cards, there is a long standing hardware acceleration bug. Here are the instructions that I send to my clients so they get the best possible experience:* Open "Adobe Acrobat Reader DC"* Goto [Toolbar > Edit > Preferences > Security (Enhanced)]* Turn OFF [Enable Protected Mode at startup]* Close down and restart "Adobe Acrobat Reader DC"* Goto [Toolbar > Edit > Preferences > 3D & Multimedia]* Turn ON [Enable playing of 3D content]* Turn ON [Enable hardware rendering for legacy video cards]* Turn ON [Enable double-sided rendering]* Set [Preferred Renderer:] to [DirectX9]* Press [OK] to close the Preferences dialog box- Open a 3D-PDF and you should be able to smoothly interact with it.- Use [Left Mouse Button] to Rotate- Use [Alt + Left Mouse Button] to Pan- Use [Right Mouse Button] to Zoom- Use [Alt + Right Mouse Button] to Zoom a windowYou should see a 3D Toolbar along the top edge of 3D view window. From there you can:- Click the [Home] icon to take you back to your default view- Click the [Views] dropdown list to choose another saved view- Click the [Model Tree] icon to expand the tree and turned items ON/OFF- Click the [Cross Section] icon and then the black triangle to change Section PropertiesHTH,Andrew Novinc.
thank you very much for your extensive answer!
Unfortunaly I still did not get the desired results; I keep on trying.
It is difficult to suggest an answer without knowing about your material and lighting settings.
Can you upload the dgn?
here are the dgn and the draped orthophoto.
In your dgn I adjusted the dcdrape material increasing the Diffuse value to 100%.
This seemed to improve to appearance of the orthophoto.
I also noticed that you have some objects that don't have a material applied. They appear overly bright. If you hadn't planned on applying a material to them you may want to reconsider this. You can easily control their brightness by assigning a simple material to those objects. To do that you can just create a new material and call it something like "Simple". Set the Base Color to Use element color (the little color palette icon). The Diffuse value should be at 50% by default. You can now apply this material to those object that don't already have materials. They will still display their original element color, but now you can control how bright they appear by adjusting the Diffuse value.
I hope this helps.
