Standard Bump Maps
Standard Bump Maps are created by using one image to represent the height of the bumps, and a base color, or another image is used to represent the underlying material.
The
IRender nXt
Material editor can create
Bump Maps
with underlying textures (beside the bump map) and other special features.
Bump map editor
There are two ways to do bump maps.
- You can use the original texture as a bump map (See: Automatic Bump Maps ) or
- You can provide a separate image to use a bump map.
With IRender nXt, you can use the nXt material editor to create your own materials, with many additional material features, including bump mapping.
After creating an nXt material, the user can automatically create a material for SketchUp which appears similar, (but of course with no bump mapping or reflective properties). This SketchUp material will automatically render using the nXt material with IRender.
Creating a Bump Map Image
Creating your own "true" bump maps of complex images is probably difficult. You would take a standard image of the surface and color it by depth. A good Photo Shop user may be able to do this.
But you may be able to add realism to some images more easily. Emacs!
Here you could use a paint program to define bump levels - even just black and white.
Here is a brick wall image:
Here I have used a paint program to put the bricks at one level, and the mortar at another level:
Here is a rendering of the base texture on a brick wall with no bump maps:
Here is a rendering with this bump map applied to the rendering as well.
But we also have another feature, called "auto Bump" which provides a similar effect to this simple bump map.
