ADI802A Produce photo-realistic images from an Architectural 3D model

Topic 2 Introduction to 3D Studio Viz

Exercise 1 Creating a light fitting

1. Open 3D Studio Viz

2. Set the Units from the Customize > Unit setup to mm.

3. From the Command panel use Create > Tube to draw a tube, then use modify to set the size to the ones shown in the image below.

 

4. Change to 4 viewport's

5. Ok lets cut some holes in the tube to make an interesting light fitting. To do this we will create some boxes as the cutting tool. Draw the first box and position it as shown below.

6. From the Tool menu choose Array.

7. Enter the amounts highlighted above. It should like the model below.

8. Now we will look at how we can copy them to the other side. Select all the boxes and hold done the shift key while you move them to the new location. A dialogue box will pop up, you can clone them as an instance. This mean if you change the original size it follows through to all the cloned versions.

9. Now we will look at how we cut then away from the tube. The first thing to do is to link them together using the union command. First select the first box. As shown in the command panel choose Create > Geometry > Compound Objects > Boolean and then change the Operation to Union, the choose the "Pick operand B" button and select the next box. Repeat for the remainder. When all the boxes are unioned together we can now subtract then from the tube.

10. Select the tube then Create > Geometry > Compound Objects > Boolean and then change the Operation to Subtraction (A-B) then choose the "Pick operand B" button and select the box. It should look like the image below. Repeat for the second group of boxes.

 

11. Your model should now look like the one below.

12. Choose the material editor from the toolbar. Create a new material that is Multi/Sub Object as shown in the image below.

13. Keep the old sub material and change the "Set Number" to 2.

14. Change the sub material colour parameters as shown.

15. Now we will change the parameters of material 2 (inside of lamp) to a white with 100 % self- illumination. Indicated on the image below.

16. Your model should now look like the one below. Move it around using the orbit command from the navigation panel. (Bottom right corner of image)

17. Use the tube command again to create the outer and inner rings. Then add the first box the same thickness as the tubes. Change the pivot point of the box. This will help us rotate and copy.

18. Rotate and hold down the shift key to clone the rectangles in the frame. If your switch on "snap" toggle before you rotate it will be easier to go through 90 deg.

19. To draw the light bulb we will start with a spheres and then edit the mesh to move the vertices to get the bulb shape.

20. Select a group of vertices in the front viewport and relocate as shown below.

21. Select a row of vertices and relocate as show below. Lock in your selection then move to the top view and use the scale command to achieve the desired result. Continue this with the other rows of vertices to get a smooth effect.

22. Keep editing the vertices to achieve a light globe shape.

23. Move the globe into the light fitting and globally scale to the correct size. Apply the white self-illumination material to it.

24. Add the top for globe socket as shown below. Start with a cylinder and edit the vertices as you did with the globe to get the desired shape.

25. You can add the cord to the model using a cylinder. Use the modify command to edit the height parameter.
