The proliferation of mobile devices and easy internet access open up a huge number of opportunities for many people around the world. Anywhere anytime learning is one of these opportunities. Despite the prevalence of mobile learning, it is not always possible to find a convenient application that covers several areas. The uniqueness of the research is the development of an application that could become an excellent solution for studying several academic disciplines and developing spatial skills on the example of a certain subject. As a result, an application model that allows studying geometry, physics, chemistry, geography, economics and social studies has been developed; these are the disciplines that most involve spatial thinking. Spatial skills are taught based on two-dimensional and three-dimensional objects, animation, images, maps. The use of augmented reality technology to increase the effectiveness of teaching spatial thinking has been considered. The model implementation allows using the app for independent activities and educational purposes.

We found that first-year engineering students often have difficulties to visualize and manipulate three-dimensional objects mentally, especially if the assembly involves multiple parts that need to work together in sequence to produce a required function. Ultimately, this lack of ability leads to poor representation of intended students’ design concepts in paper sketches, as well as poor or unacceptable detailed designs in CAD. Therefore, it is imperative that students develop their ability to manipulate complex objects in space very early in their academic careers. In this context, this paper focuses on the introduction and implementation of a challenging design-build project in the first-year engineering design course at UOIT intended to provide students with early opportunities to physically realize the spatial relationships and the three dimensional causality of the interaction of moving parts in an assembly.

Spatial skills are an important component of the mathematics curriculum. Both teachers and students have to make use of their spatial skills when using two-dimensional diagrams to represent three-dimensional objects and when interpreting photographs or television images (see, e.g., Pohl [1986]; Greenfield [1987]: Smith [1987]; Bright and Harvey 11988]: Carroll [1988]).

Collision between rigid three-dimensional objects is a very common modelling problem in a wide spectrum of scientific disciplines, including Computer Science and Physics. It spans from realistic animation of polyhedral shapes for computer vision to the description of thermodynamic and dynamic properties in simple and complex fluids. For instance, colloidal particles of especially exotic shapes are commonly modelled as hard-core objects, whose collision test is key to correctly determine their phase and aggregation behaviour. In this work, we propose the Oriented Cuboid Sphere Intersection (OCSI) algorithm to detect collisions between prolate or oblate cuboids and spheres. We investigate OCSI’s performance by bench-marking it against a number of algorithms commonly employed in computer graphics and colloidal science: Quick Rejection First (QRI), Quick Rejection Intertwined (QRF) and a vectorized version of the OBB-sphere collision detection algorithm that explicitly uses SIMD Streaming Extension (SSE) intrinsics, here referred to as SSE-intr. We observed that QRI and QRF significantly depend on the specific cuboid anisotropy and sphere radius, while SSE-intr and OCSI maintain their speed independently of the objects’ geometry. While OCSI and SSE-intr, both based on SIMD parallelization, show excellent and very similar performance, the former provides a more accessible coding and user-friendly implementation as it exploits OpenMP directives for automatic vectorization.

Mountain Disasters

Climate change increases the frequency of localized heavy rains and typhoons. As a result, mountain disasters, such as landslides and earthworks, continue to occur, causing damage to roads and residential areas downstream. Moreover, large-scale civil engineering works, including dam construction, cause rapid changes in the terrain, which harm the stability of residential areas. Disasters, such as landslides and earthenware, occur extensively, and there are limitations in the field of investigation; thus, there are many studies being conducted to model terrain geometrically and to observe changes in terrain according to external factors. However, conventional topography methods are expressed in a way that can only be interpreted by people with specialized knowledge. Therefore, there is a lack of consideration for three-dimensional visualization that helps non-experts understand. We need a way to express changes in terrain in real time and to make it intuitive for non-experts to understand. In conventional height-based terrain modeling and simulation, there is a problem in which some of the sampled data are irregularly distorted and do not show the exact terrain shape. The proposed method utilizes a hierarchical vertex cohesion map to correct inaccurately modeled terrain caused by uniform height sampling, and to compensate for geometric errors using Hausdorff distances, while not considering only the elevation difference of the terrain. The mesh reconstruction, which triangulates the three-vertex placed at each location and makes it the smallest unit of 3D model data, can be done at high speed on graphics processing units (GPUs). Our experiments confirm that it is possible to express changes in terrain accurately and quickly compared with existing methods. These functions can improve the sustainability of residential spaces by predicting the damage caused by mountainous disasters or civil engineering works around the city and make it easy for non-experts to understand.

Three Dimensional Shape

Perceiving the shape of three-dimensional objects is essential for interacting with them in daily life. If objects are constructed from different materials, can the human visual system accurately estimate their three-dimensional shape? We varied the thickness, motion, opacity, and specularity of globally convex objects rendered in a photorealistic environment. These objects were presented under either dynamic or static viewing condition. Observers rated the overall convexity of these objects along the depth axis. Our results show that observers perceived solid transparent objects as flatter than the same objects rendered with opaque reflectance properties. Regional variation in local root-mean-square image contrast was shown to provide information that is predictive of perceived surface convexity.
