Accordingly, you always have to be mindful of switching back to the correct Absolute/Incremental Mode when working with both.

However, with controls that use G90/G91 to specify Absolute/Incremental Mode respectively, whichever of these G Codes is specified last will determine the Modal State for Absolute/Incremental Mode. With a Lathe control that uses specific axes addresses for Absolute and Incremental, neither Absolute, nor Incremental is truly Modal. It is actually possible, just not as probable to use as with a Lathe. I should qualify the following statement made in my previous Post The same rules apply for changing to the correct Absolute/Incremental for the Blocks following the execution of the above Lathe Command Block.

The following example is for a Fanuc Lathe Control that is set to use G Code System B, or C. If the next Block were to be an Absolute move, you would have to ensure that it contained G90, as the example Block above will leave the control in Incremental Mode. The above Block will Linear Interpolate to the Absolute Position of X100.0 and move Y-50.0 from the Y position prior to executing the Block. There are other makes of controls that use G90/G91 to specify Absolute/Incremental Mode.įollowing is an example of using Absolute and Incremental in the one Block with G90/G91. Accordingly, you always have to be mindful of switching back to the correct Absolute/Incremental Mode when working with both.Īlthough G90/G91 are primarily used with Mill Controls to specify Absolute and Incremental Mode, Lathes with Fanuc Controls set to use G Code System B, or C also use the same G Codes. Thus,Ĭat_matvec -4x4 DSET::IJK_TO_DICOM_REAL DSET::IJK_TO_DICOM_REAL -IĪs to your 2nd question, I don't quite understand what you are asking.Click to expand.It is actually possible, just not as probable to use as with a Lathe. You can perform matrix multiplication of these, such as matrix multiplying the forward and inverse matrix of each, by naming more than one matrix in order, and including a '-I' after one, if you wish. should map (x, y, z) coordinates to (i, j, k) You could invert one of these, if you would like: You could redirect the output of either to a file by putting '> FILE' or '> FILE' at the end (overwriting or appending FILE, respectively).

You can add '-4x4' as an option to either to see the 'full' 4x4 matrix. (noting that 'DSET' above is generic placeholder for a filename, but 'IJK_TO_DICOM_REAL' is actually a specific label that happens to be written in all-capital letters) and if you want to see the 3x4 matrix that can map (i, j, k) to an associated 'cardinal' set of coordinates, that the GUI uses, you can run: If you want to see the 3x4 matrix that maps a set of (i, j, k) values to a physical location in scanner coordinates for a given DSET, you can run: The matrix that maps a set of (i, j, k) values to an (x, y, z) location is internally 4x4, but the bottom row is constrained to be (0, 0, 0, 1), so it is effectly 3x4, where the first three columns for a 3x3 matrix that multiples a column vector of (i, j, k) values, and the last column is then added to the result. *notation note below: for simplicity, I sometimes abbreviate '(i, j, k)' as 'ijk', and similarly for xyz. (In the 2nd paragraph, I am not sure I would call 3dUndump+3dmaskdump a black box- each specifies what it does.) In the first paragraph, what parts of AFNI are you referring to? The GUI, or some other set of programs/functions?
