Modeling the room

One of the common misconceptions about photorealistic modeling and rendering is that it requires very detailed models before the rendering is effective. This simply is not true with today's software sophistication. The gallery scene you'll be modeling here is simple and easy to produce in SketchUp, just like the majority of rooms in the real world:

  1. Start by firing up SketchUp; then select Model Info from the Window menu.
  2. Select Units from the list on the left.
  3. Set the units to the values shown in the following screenshot. You can use inches if you like, but you may find it easier to follow if you use millimeters:

  4. Close the Model Info dialog window by clicking on the red X button.
  5. Start modeling by selecting the Rectangle function from the Draw menu.
  6. Click on the origin and draw a rectangle of any size. Click on the left-mouse button to place the opposite corner and create the rectangle.
  7. Now, type in 4000,10000. This appears in the little text box at the bottom-right corner of the screen (VCB). Hit Enter, and your rectangle will resize to 4,000 mm by 10,000 mm (4 x 10 meters).

  8. Rotate the view by pressing the middle-mouse button (MMB or scroll wheel) and moving the mouse. Now, select the Push/Pull tool and click on the rectangle, moving the mouse to extrude the rectangle into a box, as seen in the following screenshot:

  9. Type 3000 and hit Enter.

  10. Draw a rectangle on the end face, as shown in the previous screenshot.
  11. Now, select and delete the face (hit the Delete key or right-click and select Erase from the context menu).
  12. Triple-click on the geometry. Notice how all the connected faces are now selected.
  13. Right-click and select Reverse Faces. The outside faces will now be drawn in a darker shade. We need to do this because we're going to place the camera inside the room you've just created.
