We’ve already explored axonometric and perspective representations of the building in the 3D window. These views are created with OpenGL technology, capable of showing simple textures and vectorial-cast shadows of the sun, as well as making transparent objects disappear. If we want to see a more realistic view of the building, with ray-traced transparency and reflectance, mirror effects or soft shadows, or perhaps show the project as a hand-made sketch, we’ll have to create these images separately using the built-in rendering engines of ArchiCAD. Switch to the Project Map in the Navigator. Display the floor plan view of the 1st Story. Double-click on the Camera tool in the Toolbox to open the Camera Settings dialog. We’re going to view the building from the ground, so please enter 1800 mm for the Z value of the Camera. Set the height of the target point to 45 thousand mm. Click “Apply”. Zoom out. We need two clicks to place the Camera on the floor plan. First we place the camera itself, then the target point. As soon as the camera is placed, a new model view is created in the Project Map. Close the Camera Settings dialog box. Let’s set the transparency of the materials. Select “View … 3D View Options … 3D Window Settings…” menu to open the corresponding dialog. Turn on the “Transparency in Shading” option. Click “OK”. Double-click on Camera 1 to open its view. It might seem that we are too close to the building. Return to the floor plan view and move the camera on the floor plan. Zoom in to the camera and select it. Click on it and select the “Move Sub-item” from the Pet Palette. Move the camera further from the building. Open the Camera view again. Please note that it is also possible to Orbit and Explore in 3D view. When the perfect view is found in the 3D window, right-click on the “Camera 1” view in the Project Map of the Navigator, and select “Modify this Camera to Current view” from the context menu. Select “Document, … Creative Imaging, … Photo Rendering Settings…” from the menu. Select the “Light Works Rendering Engine” at the top. This engine will provide the most photo-realistic results. Click the “Size to 3D window” button to specify the size of the rendered image according to the size of the 3D window. Set up effects as shown. For a better result we’ll use only Lamps and some Ambient light as light sources, so de-select the Sun and Camera lights. The use of LightWorks-specific Lamps will give us the required control over lighting and shadow conditions. Open the “Light work environment” panel of the dialog. De-select the “Render Background with Internal Engine” option. Click on the Background button and select “Image” from the list. In the parameter box on the right, click on the “File Name” parameter. Search for the image “Sky clouds 2” Jpeg image in the “Simple 1024 by 768″ folder of the Background folder of the ArchiCAD Library. Click “OK”. Since we have decided to use Lamps but not the built-in Sun, we’ll have to place some lights on the floor plan ourselves. Display the 1st Story from the Project Map. Double click the Lamp Tool to open the Lamp Default Settings dialog. Select the “Sun Object” from the Lightworks library. Display the “Parameters” page of the dialog and enter 40 for the color and intensity. Click “OK”. Place the sun object anywhere on the floor plan. The layer of the sun is hidden, so activate the “Show Layer” button in the upcoming dialog box. Open the Lamp Settings dialog once again. Select the “Sky Object”. Set the intensity to 75, and the color to light blue. Place the object beside the sun object. You may zoom in to these objects on the floor plan. These objects will act as general sun and sky light sources. Sky light being the diffuse light coming from the sky hemisphere. We won’t have to set sun position again, since these objects take it directly from the camera settings. All we have to do now is to select the “Camera 1” view from the Project Map and select “Document … Creative Imaging … Photo Render Projection” from the menu. The rendered image is ready in a matter of seconds. Please save the rendered image using “File … Save as” option from the menu. Please save the image to the “Exercise” folder. Enter any desired file name and select the JPEG image format.
