Tetra-cubes is similar to the well-know marching-cubes technique, but is basic building block consists of tetrahedral cells instead of cubes. . When the original cells are not tetrahedral cells, tetra-cubes converts them to tetrahedra. We show that our technique is simpler than marching-cubes and does not have ambiguity configurations, leading to simpler iso-surface generation. We advocate the use of tetra-cubes due to its simplicity of implementation and generality.  aComputacao graficaa  aGraphic computation  aImage processing  aProcessamentode imagens1 aSILVA, C.
