Blister Texture

This plug in texture creates the appearance of a random splattering of blisters on any surfaces it is applied to. There are a number of optional settings and the size of repeat pattern is (like all other textures) dictated by the size of the Texture Axes.

Remember that the .DLL and .TFX files for textures should be located in the textures subdirectory.

This plugin is controlled through the dialog below:

The controls in this dialog effect the appearance of the texture but the overall scale (which governs the appearance) is controlled by the relative size of texture axis to the model on which the texture lies. Check out the example model included with the DLL and SFX files.

As usual the X Y and Z scaling are multipliers on any scaling derived from the texture axes.

The effect of the other settings are as follows:

If the colour bumps flag is set then the colour set in the swatch beside it is applied to the whole blister.

The texture can produce three types of blisters:

The blisters can be given the appearance of having less heights by entering a number in the range [0 - 1] in the Blister Height edit box.

The Blister Radius (in the range [0 - 1]) controls the radius of the blister. This setting may be used in conjunction with the scaling factors and Texture Axis size to contol the apparent number of blisters per unit surface area. (For example making the texture axes large and using a small blister radius gives the surface the appearance of having ony a few blister. Alternatively making the texture axis small and setting the radius to 1.0 gives the surface the appearance of being highly blistered.) This point is illustrated in the figures below. The sphere on the left has small blisters but a large set of texture axes, the sphere on the right has large blisters but a small set of texture axes. (The models (.MFX files) for these spheres are included in the download archive)
