2 Translated cube plus translated cylinder minus two rotated cylinders. Chandrajit Bajaj et al. Phil. Trans. R. Soc. A 2008;366: ©2008 by The Royal Society

3 (a) Progressive geometry and (b) dataflow of the generating expression. Chandrajit Bajaj et al. Phil. Trans. R. Soc. A 2008;366: ©2008 by The Royal Society

4 Pipelined execution: (f ∼ g ∼ h):x=(f ∼ g):(h:x)=f:(g:(h:x)). Chandrajit Bajaj et al. Phil. Trans. R. Soc. A 2008;366: ©2008 by The Royal Society

5 Parallel execution: [f,g,h]:x= 〈 f:x, g:x, h:x 〉. Chandrajit Bajaj et al. Phil. Trans. R. Soc. A 2008;366: ©2008 by The Royal Society

6 The whole scheme holds for d odd; for d even, the last block row should be discarded (ki denotes the cardinality of the k-skeleton, i.e. the number of k-cells). Chandrajit Bajaj et al. Phil. Trans. R. Soc. A 2008;366: ©2008 by The Royal Society

7 A docking pair of molecules M1 and M2: (a) the docked complex M1 ∪ M2, (b) the difference M1\M2, (c) the difference M2\M1, (d) the intersection M1∩M2, (e) zoom in on M1\M2, and (f) zoom in on M2\M1. Chandrajit Bajaj et al. Phil. Trans. R. Soc. A 2008;366: ©2008 by The Royal Society

8 A toy heart model: definition of profile and section curves; transfinite operator profileproduct; interior surface1 and exterior surface2; volume mapping. Chandrajit Bajaj et al. Phil. Trans. R. Soc. A 2008;366: ©2008 by The Royal Society

9 Piecewise approximation of a toy heart model. Chandrajit Bajaj et al. Phil. Trans. R. Soc. A 2008;366: ©2008 by The Royal Society

10 (a–d) The univariate vector mappings profile : 3 and section : 〈 2.5,2 〉 are evaluated here on the intervals [0, 1] and [2π/3, 2π], respectively. Chandrajit Bajaj et al. Phil. Trans. R. Soc. A 2008;366: ©2008 by The Royal Society

11 Spatially realistic finite-element reconstruction of human heart from patient-specific imaging data (Bajaj & Goswami 2008): (a) volume rendering from CT Angio imaging of a human thoracic region, (b) the initial reconstructed heart model extracted from the r...

12 A cross-sectional unfolded layout of the interface of a typical frog NMJ, showing the cell membrane parameters to be reconstructed via spatially realistic finite-element modelling using Proto-Plasm. Chandrajit Bajaj et al. Phil. Trans. R. Soc. A 2008;366: ©2008 by The Royal Society

15 Three-dimensional manifold in figure 6c. Chandrajit Bajaj et al. Phil. Trans. R. Soc. A 2008;366: ©2008 by The Royal Society

16 (a) A single slice of a transmission electron micrograph of a NMJ showing the presynaptic axonal end with many spherical vesicles filled with neurotransmitters (pointed to by arrows). Chandrajit Bajaj et al. Phil. Trans. R. Soc. A 2008;366: ©2008 by The Royal Society
