One of them is the Mental Cutting Test (MCT), the exercises of which offer a 2D projection of a 3D shape and a 2D plane, and testees should determine the shape of their intersection. MCT exercises need various 2D and 3D assets that should be developed before publishing a test. In recent decades, very few exercises have been available to instructors and researchers. In 2019, we published our first solution that could be used to calculate the intersections of MCT scenarios, then render or export their assets using Blender. This paper proposes an extended, open-source package for Blender that generates assets of MCT exercises by permuting predefined shapes, cutting planes, rotation, and scale operators. The additional wrapper script helps users use the package for various purposes, such as developing exercise offering methods, designing exercises, practicing, or organizing exams and measurements.}, year = {2023}, eissn = {2352-7110}, orcid-numbers = {Tóth, Róbert/0000-0002-7583-7433; Hoffmann, Miklós/0000-0001-8846-232X; Zichar, Marianna/0000-0002-1943-6053} } @article{MTMT:33573320, title = {Lossless Encoding of Mental Cutting Test Scenarios for Efficient Development of Spatial Skills}, url = {https://m2.mtmt.hu/api/publication/33573320}, author = {Tóth, Róbert and Hoffmann, Miklós and Zichar, Marianna}, doi = {10.3390/educsci13020101}, journal-iso = {EDUC SCI}, journal = {EDUCATION SCIENCES}, volume = {13}, unique-id = {33573320}, issn = {2227-7102}, abstract = {In the last decade, various mobile applications have been developed to improve and measure spatial abilities using different spatial tests and tasks through augmented reality (AR), Virtual Reality (VR), or embedded 3D viewers. The Mental Cutting Test (MCT) is one of the most well-known and popular tests for this purpose, but it needs a vast number of tasks (scenarios) for effective practice and measurement. We have recently developed a script-aided method that automatically generates and permutes Mental Cutting Test scenarios and exports them to an appropriate file format (to GLB (glTF 2.0) assets) representing the scenarios. However, the significant number of permutations results in more than 1,000,000 assets, requiring more than 6 GB of storage space. This paper introduces an encoding scheme consisting of four stages to handle this issue through significantly reducing the storage space, making the app suitable for everyday individual use, even on a mobile phone. The proposed method encodes a subset of assets from which it can decode the whole dataset with 3% time complexity compared to classical Blender’s computations, exceeding the compression ratio of 10,000 and storage space saving 99.99%. This paper explains the features of the original assets, introduces the encoding and decoding functions with the format of documents, and then measures the solution’s efficiency based on our dataset of MCT scenarios.}, year = {2023}, orcid-numbers = {Tóth, Róbert/0000-0002-7583-7433; Hoffmann, Miklós/0000-0001-8846-232X; Zichar, Marianna/0000-0002-1943-6053} } @inproceedings{MTMT:33066496, title = {Educational Applications to Support the Teaching and Learning of Mental Cutting Test Exercises}, url = {https://m2.mtmt.hu/api/publication/33066496}, author = {Tóth, Róbert and Tóth, Bálint and Zichar, Marianna and Fazekas, Attila and Hoffmann, Miklós}, booktitle = {Proceedings of the 20th International Conference on Geometry and Graphics, ICGG 2022}, doi = {10.1007/978-3-031-13588-0_81}, unique-id = {33066496}, abstract = {Developing or measuring the spatial skills of people is still an interesting research topic nowadays.
