Simple Bump Map

images/download/attachments/27789732/viz_icons_simplebumpmap.png
With this plug-in you have the opportunity to simulate complex surface structures. Instead of many triangles to render a 3D object with many structures on its surface you can use bump mapping to get a similar result.

You can only use a gray scaled image as normal map. If you want a more accurate result and better effects please use the Bump Map plug-in instead which is using an RGB normal map image.

To generate a Simple Bump Map you can use the plug-ins for Photoshop, Gimp, the built-in functions of your modeling package or NVIDIA’s tool Melody. The Height Map (used for parallax mapping) should be a grayscaled image (white -> highest, black -> lowest bumps).

Simple Bump Map Properties

  • NormalMap: Move an normal map via drag and drop onto this field. Normal maps are images which store a direction of normals directly in the RGB data.

  • HeightMap: Move an height map via drag and drop onto this field. The Height Map file is only visible and used when parallax mapping is enabled.

  • Light Source: Choose the light source in the range 1-8. Please consider that only one light source is possible. By default the first light source is used.

  • Position X and Y: The position of the normal map in X-direction and Y-direction.

  • Scale X and Y: Here you can scale the normal map, respectively change the width and height size of the image.

  • Wrap: Repeats or clamps the bump map for the image.

  • Toggle X and Y: Changes the direction of the normals stored in the normal map image.

  • Scale Height: Changes the intensity of the bump map effect. Scale Height is visible when parallax mapping is enabled.

  • Parallax Mapping: With this additional map the texture will have more apparent depth and the object is more realism.
