Shear Warp + SIMD

After finally sitting down and putting some thought into how to use SIMD with the Shear Warp algorithm, it doesn't seem that applicable. Unlike Ray Casting where there was additional processing going on, this algorithm basically consists of copying each voxel to it's pixel in the output image, handling the transparency value of the voxel.

The warp part of the algorithm involves a few calculations, however compared to generating the image it only adds a very small amount of time to the render, so I didn't feel it was worth spending time on.

I implemented some SIMD code to aid the calculations involved in writing a transparent voxel to the output image, but only succeeded in slowing things down.

I looked into processing 4 voxels at once. This would involve doing calculations for the red, green and blue of each pixel at the same time. This offers no benefits over processing single voxels though, as there are no common calculations happening to all four.

On Monday, I will start the report. My plan has altered slightly after the tutor meeting to include design sections for the two algorithms and the program. Also I missed out the Evaluation section.
