The Mercedes-Benz G-Class, sometimes called G-Wagon (short for Geländewagen, "terrain vehicle"), is a four-wheel drive automobile manufactured by Magna Steyr (formerly Steyr-Daimler-Puch) in Austria and sold by Mercedes-Benz. Originally developed as a military off-roader, later more luxurious models were added to the line. In certain markets, it has been sold under the Puch name as Puch G.

The G-Wagon is characterised by its boxy styling and body-on-frame construction. It uses three fully locking differentials, one of the few vehicles to have such a feature.

Despite the introduction of an intended replacement, the unibody SUV Mercedes-Benz GL-Class in 2006, the G-Class is still in production and is one of the longest-produced vehicles in Daimler's history, with a span of 42 years. Only the Unimog surpasses it.[3]

Japanese tuning company, Kid's Heart, produced 500 official units of a 180sx and Silvia hybrid known as the Sil80 (SilEighty). These cars were built upon the standard 1998 180sx platform but had the headlamps, front wings, hood, front bumper and fixings from a Nissan Silvia swapped over. These cars were also given some mechanical and tuning upgrades, including revised suspension, an improved limited-slip differential and an ECU tune.

* In 1995, Honda introduced the Integra Type R to the Japanese domestic market. The Japanese specification Type R came standard with a 147 kW (200 PS; 197 hp) factory-tuned variant of the B18C engine. Power figures varied slightly between markets, with USDM cars putting out 145 kW (198 PS; 195 hp) and UK-spec cars making 139 kW (190 PS; 187 hp). Equipped with a close-ratio 5-speed manual transmission and a helical-type limited-slip differential, the Integra Type R had significantly improved performance and handling relative to the GS-R/Si/SiR-G Integra. Made in Blender 3.1.2

The Bianchi-Pinkall surfaces are a class of flat tori (surfaces with zero Gaussian curvature) embedded in the three-sphere, identified by Luigi Bianchi in the late 1800s and further developed in the context of modern differential geometry by Ulrich Pinkall.

It is installed above the ESP discharge, where, upon start-up, sand-breaker  uses  differential  pressure  to  push  fluid  and entrained solids through tubular ports in one flow path, to the surface.

Based on a k-Noid. In differential geometry, a k-noid is a minimal surface with k catenoid openings. In particular, the 3-noid is often called trinoid. in this case 8 noid. The first k-noid minimal surfaces were described by Jorge and Meeks in 1983

This high-precision swept trajectory mesh visualizes the continuous deformation of a 15-tetrahedra Kaleidocycle according to Theorem 5.1(Kaji et al., 2026). The surface is generated by connecting corresponding vertices of the central curve across 34 sampled time frames of the periodic motion, creating a space-time manifold embedded in 3D.
Constructed from explicit elliptic theta function solutions with rigorous numerical checks: curve and configuration closure residuals reach machine precision (~5×10⁻¹³). The mesh contains 510 vertices and 990 triangles and represents a 2-manifold with boundary.
It demonstrates a finite, high-accuracy replay of the integrable deformation of a closed tetrahedral linkage, useful for mathematical visualization, mechanism design, and discrete differential geometry research.

This 3D model demonstrates a bevel gear mechanism designed and animated in Autodesk Inventor.

Bevel gears are used to transmit power between shafts that intersect, typically at a 90-degree angle. This mechanism shows how rotational motion is transferred efficiently between two perpendicular shafts.

Key features of this model:

Accurate bevel gear geometry

Smooth gear motion animation

Designed using Autodesk Inventor CAD

Demonstrates mechanical power transmission

Applications of bevel gears include:

Automotive differentials

Industrial machinery

Gearboxes

Mechanical power transmission systems

High-fidelity analytical torus generated via the PAPP v3.1.0 system (Phase 7.5). 

This model represents the positive branch (f⁺) of a "Bonnet Pair"—a rare configuration in differential geometry where two non-congruent surfaces share identical metrics (isometry) and mean curvature.

Based on the 2025 research by Bobenko, Hoffmann, and Sageman-Furnas, this surface is a compact torus in ℝ³ with numerically verified isometry against its twin branch (f⁻) at machine precision (E_rel ≈ 10⁻¹⁴).


Technical Specifications:

• Topology: Closed Manifold Torus (Euler Characteristic χ = 0).

• Resolution: 80x80 (6,400 vertices, 12,800 triangular faces).

• Parameters: Optimized at the critical closure value τ* = 0.16006 (Ratio 1/1).

• Analysis: Validated via Spectral Gap and Persistent Homology (TDA).


Ideal for mathematical visualization, topological research, and computational geometry studies.
