The spline curve is the skeleton structure of all Cinema 4D objects. Using precise mapping will help you create and control depth, perspective and realistic shapes. Using precision points, using a grid display with grid snapping is the primary tool for creating your own defined shapes.
For simple exercises on precision tools, we can build a simple table with legs and use the capture for precise placement. This exercise will use fixed coordinates, multiple perspectives, and a useful grid display. We'll start with a spline, use the special spline effects available and then stretch our shape to create a table with a certain style.
For beginners, make sure the grid is turned on. Below the main menu there is an embedded menu, your "viewport" and above the stage. In ' Edit -> Configure -> Filters ' you will see a set of main viewing options. Make sure the 'Grid' option is selected. You will immediately see your grid appear and disappear, check this box.
Start with a rectangular spline that is 8 meters long and 4 meters wide. Change the plane view to ' XZ'. Convert the rectangle by selecting the rectangle and enter the ' C' key. On your two new aircrafts, adjust the "' Y' coordinate values. I chose 25 and 5 to evenly increase each one.
Now create a 'Loft Nurbs'. Nurbs is very interesting. Even though this name makes us fall into fantasy, Nurbs' Nurbs' actually represents something: ' non-uniform rational B-spline' this acronym actually belongs to the computer Graphical modeling, not Cinema 4D, you can find more information at the Wikipedia link included at the end of this article. With the nurbs model, you can travel from the 2D spline world to the 3D world.
Select your three splines and drag them under the new attic nurbs to make them children. Now render your project to see what you have created so far. You can instantly see your desktop with precise dimensions and rich 3D detail. I usually add a special material to create any new object for me to make me more real. The Cinema 4D library is really rich, it's easy to get lost just for experimentation, but on my desk I chose a marble finish ' Sancai' from the material group. I can't resist this, it is indeed an ancient Chinese technology.
From Wikipedia:
"Three talents from
[Chinese: literally ' three colors '] is a ceramic decorated with three mixed colors. Three talents The ceramic is made of white clay and is coated with a layer of glaze and fired at a temperature of 800 degrees Celsius. "
I drifted here, but the material library at least increased the mathematical dimensions and drawing capabilities of your project. When I applied this marble texture and rendering, I immediately saw a desktop with different colors and textures, just like real marble ceramics, small classes and culture. Apply materials immediately to make your items look good.
It's very easy to add some legs on our desktop. Select the top view of the placed leg. Create a cube. Under ' Attributes -> Object Attributes ' I used 1m in ' x'. And ' y' size. When you use the model tool [the third at the top of the tool menu, the leftmost of the standard layout], then select "Move" #39; from the ' Properties -> Move ' menu, the snapshot settings are right The third option on the side. Enable snapshots with default settings. Now pick up your cube and move it to the top left of the desktop. You will see the lock with snap enabled enabled. Now expand the height of a single cube. You may want to rename it 'leg1' at the moment. Under the object properties, I lifted my leg up 2 meters and then used the green adjustment arrow to move under the table. Use your rights & #39; and the front ' side view options at this point [' F3' and ' F4']. From these sections, you can clearly see that your legs are just touching the bottom of the table.
Go back to the top view and drag your single leg to the top left corner of the table. Once the snapshot settings are enabled, it should use a uniform indicator to jump to the corner [my is ' X:-3.5', ' Z:1.5']. Now make three new legs. Select legs 1, 2 and 3 individually and drag to the corner of the table. Once snapping is enabled, they should be locked in place using the correct height set in the first cube model. Sometimes add slightly different ceramic material to your legs to get a little offset, and you have it, an attractive table with precise dimensions using splines, of course, ' nurbs'.
