Applying a 3D Marble Texture

1. Right-click the material behavior in the specification tree then select xxx_Rendering object > Definition to display the Rendering Properties dialog box.

2. Select the Texture tab then select Marble in the Type list.

   
   
   

   When a 3D texture is selected, the corresponding texture image is projected onto the object in the geometry area so that you can get a better idea of the final result:

   
   
   

   However, note that:

   
   
   • the projected image does not reflect exactly what you get when rendering the image
   • the texture has a low resolution in order not to deteriorate performance and as a consequence, the image projected onto the object may sometimes be pixelated.

   Warning: You can also choose a mapping type but do not forget that this mapping is relevant for real time display only, it has no impact when computing the rendered image.

3. To modify the lighting color effect of the half-vein, just click the desired arrow then drag it to the left or to the right to change the width of the corresponding color. You can also drag an arrow down to disable the corresponding color:

   
   
   

   Note that if you double-click an arrow, the Color chooser is displayed to let you select the desired color.

4. The Deformation area lets you define noise parameters.

   Refer to About 3D Textures for detailed information.

5. Use the Bump area to define an Amplitude value but this time, in order to create an "embossing".

6. Use the Transformation area to adjust the mapped texture.

7. Click OK when satisfied with your parameters.

The two images below compare the different results you can obtain using a standard texture and a 3D texture of type Marble:
