What data structure for the volume image does the VolumePro 500 take for rendering?
Memory format is slice by slice, with each slice consisting of a 2D voxel array. The arrays are packages as tightly as possible. Voxels are either 8 bits or 12 bits of a 16 bit value. The VLI can read volumes in “Vox1999a” format that is described in a document that is available on the distribution CDROM. In addition, many applications use their own standard file formats for volume images. In these cases, the application is responsible for reading and interpreting the format into host memory; then it passes the volume image in memory to the VLI for loading onto our board.
