Hypertexturing Objects Using Volume Graphics

The images on this page demonstrate how Perlin's hypertexture can be applied to volumetric data.

The volumetric data can be one of three formats:

• Calculated - mathematical formulae are evaluated at each voxel location.
• Acquired - such as CT and MRI scanned data.
• Voxelised - Volume datasets generated by voxelising an object represented by some other method, for example a triangular mesh object.

The application of hypertexture may also be controlled, by:

• Clipping - the texture is only applied to selected parts of the object.
• Blending - two or more textures can be blended together.

Clipping - this image also demonstrates how two different types of texture may be used

Blending

Other hypertexture effects include:

• Hypertextured hypertexture - hypertextures are applied to objects that are already hypertextured.
• Animation - animations can be created by altering control parameters.
