LightWave Plugin: How to Use LW9 Logo
LightWave plugin 9 logo enables you to create different kinds of animations such as Motion Graphics, Cartoon Animations, Special Effects and Technical Animation, among many more. It is a more defined continuation of the tools that were used in LightWave 8, only it comes with additional features. In this article, you will learn how to use caustics using a ball on a surface.
Step 1: Caustics Defined
Caustics is the way in which light is refracted, reflected and focused in the real world through transparent or curved surfaces. They are used when the light passes through a surface that is transparent, and there is some internal reflection, or when there is a reflection of light in a shiny surface.
Step 2: Building the Scene, Table Top
Beginning in Modeler, make a Box (X). Put in the Width as 15, Height as 1, Depth as 15, Center X as 0, Y as -0.5 and Z as 0. The Axis should be X and the segments X, Y, Z, 6, 6 and 6 respectively.
Step 3: Building the Scene, Ball
On another layer, create Ball (o). The Axis should be Y, the Sides 12, the segments 12, the Center Y 1, and the radii X, Y and Z, 1, 1 and 1 respectively. After doing this, save the object as table top.
Step 4: Building the Scene, Texturing the Table
Open the Surface Editor. The short cut is pressing F5 on the keyboard. Select and highlight the surface of the table. Put the specifications of the color that you would want. Diffusion should be at 60% and the glossiness at 16%. Smoothing should be checked. Do not close the window.
Step 5: Texturing the Ball
In the surface editor, choose the ball surface and then open the presets panel. A short cut for this is F9 on the keyboard. On the drop-down menu, choose Glass. Scroll down on that list until you reach Glass 02 preset, and double click on it for it to be applied. Click on Yes on the dialogue that pops up. The object needs to be saved again. Once you have saved it, click Send Object to Layout that is in the drop down on the top right of the window of the modeler.
Step 6: Lighting
Select light on the scene and open the properties. The ambient intensity should be 0, the light type should be Area Light, the light intensity 300%, the intensity falloff should be inverse distances, and the range should be 6. Check on Affect Caustics option. Close the dialogue box and save.
Step 7: Camera Location and Rendering
You will need to click on the translate tool when the camera is one and input the desired settings. You are also required to activate the rotate tool and input the values required. When it comes to rendering, you should click on the Render tab and then under options, click on render. Select the render tab and set the settings needed. The settings that are done above will result in a glossy effect and the caustics will be visible on the image.
