This is the dataset accompanying the paper: Ante Qu and Doug L. James. 2021. Fast Linking Numbers for Topology Verification of Loopy Structures. ACM Trans. Graph. 40, 4, Article 106 (August 2021), 19 pages. https://doi.org/10.1145/3450626.3459778. Specifically, these files correspond to all closed-loop examples in Table 1, except that we do not release the chevron 3x3 stitch pattern as it is not a collection of closed loops. Most files adopt the Binary Curve Collection (BCC) file format, which is also used by the open-source fast linking number curve verification tool released alongside this paper. The chainmail, rubber bands, and woundball examples were originally sourced from Houdini OBJ files, and we include their original files as well. The reference certificate for each [name].bcc is located at reference_certificates/[name].txt. As described in the code release, the first line indicates the number of curves in the model, and each subsequent line is a triple consisting of two curve indices (0-indexed) and the linking number between the two curves. For example, "5,6,-2" indicates that the linking number between curves 5 and 6 is -2. The linking number of any curve pair not included in the triples is zero. If a certificate file only has the first line, all of its curves are unlinked. We also include a script in scripts/dataset_referencegen.sh to generate these certificates. Simply edit the "VERIFYCURVESPATH=" line to point to your "verifycurves" executable. Below is a list of table entries and their corresponding BCC filenames: - Alien Sweater (Initial): alien_sweater_init.bcc - Alien Sweater (Final): alien_sweater_final.bcc - Sheep Sweater: sheep_sweater.bcc - Sweater: sweater.bcc - Glove: glove.bcc - Knit Tube (Initial): knittubeinit.bcc - Knit Tube (Final): knittubefinal.bcc - Chainmail (Initial): chainmail_init.bcc - Chainmail (Final): chainmail_final.bcc - Rubber Bands: rubber_bands_final.bcc - Double Helix Ribbon λ=10, 200K Segments: double_helix_ribbon_lambda10_N200K.bcc - Double Helix Ribbon λ=1K, 200K Segments: double_helix_ribbon_lambda1K_N200K.bcc - Double Helix Ribbon λ=10, 20M Segments: double_helix_ribbon_lambda10_N20M.bcc - Double Helix Ribbon λ=1K, 20M Segments: double_helix_ribbon_lambda1K_N20M.bcc - Thick Square Link: thicksquarelink_N500K.bcc - Thick Square Link, 4M Segments: thicksquarelink_N4M.bcc - Torus λ=1M, 20M Segments: torus_lambda1M_N20M.bcc - Torus λ=0, 40M Segments: torus_lambda0_N40M.bcc - Woundball ν=1K, 1M Segments: woundball_nu1K_N1M.bcc - Woundball 10K, 2M Segments: woundball_nu10K_N2M.bcc Note that some input files are B-Splines, some are uniform Catmull–Rom splines, and some are polylines. This information is encoded within the BCC files. knittubebroken.bcc: For Knit Tube, knittubeinit.bcc is from simulation step 0, knittubefinal.bcc is from simulation step 13000, and both states are unlinked and topologically valid. We also add knittubebroken.bcc from simulation step 13080, which exhibits linking violations. Rubber_bands_init.bcc: For rubber bands, we also add Rubber_bands_init.bcc for the initial state of the rubber bands. Interestingly, this configuration has zero potential linking cycle pairs. The knitted yarn models (1 to 7) are modified from Cem Yuksel's yarn-level cloth models available at http://www.cemyuksel.com/research/yarnmodels/. Download the dataset zip here.
