Volume Rendering Techniques Based on MultitexturesBachelor-ThesisConsumer graphics hardware has recently made possible to achieve interactive
frame rates for volume rendering on PCs. The introduction of 3D textures
and dependent textures made possible the implementation of more advanced
techniques like multidimensional transfer functions and tagged volumes.
As a drawback, 3D textures are not extensively used in the game industry
and therefore the available hardware acceleration is sub-optimal when
compared to 2D textures. Thereby, rendering approaches based on 2D textures
are often more than 100% faster than those based on 3D textures. The aim
of this work is to implement tagged volume visualization and volume rendering
with bi-dimensional transfer functions making use of the multitexture
approach. Since this technique is based on 2D textures and register combiners,
it can be expected that the obtained frame rates are much higher when compared
to the current implementation.
