Many students make the critical mistake of assuming that a high score in general English (like IELTS or TOEFL) automatically qualifies them for technical communication. This is false. General English focuses on social interactions, storytelling, and emotions. focuses on facts, processes, measurements, and instructions.

This course is designed for elementary-level learners who need to communicate effectively in technical environments such as engineering, IT, and manufacturing. Practical Focus

The course introduces the building blocks of professional technical writing. Students learn to:

Technical English 1: The Essential Guide for Beginners Technical English 1 is the foundational level of English for specific purposes. It bridges the gap between general language skills and specialized industry communication. This guide outlines the core components, target industries, and essential vocabulary needed to master this level. 🎯 Target Audience and Industries

Obi Rope

Obi Rope will allow you to create realistic ropes and chains fast, with absolute control over their look.

  • Procedural smooth mesh generation using splines, complete with tangent space updating and normal map support. No need to manually generate geometry for your ropes.
  • Change rope length at runtime, Tearable/cuttable rope, Closed loops.
  • Modular solver: don't waste performance, only use the constraints your rope needs.
  • Bending constraints and per particle pin constraints.
  • In-editor simulation preview.
  • Easy-to-use editor particle tools: selection, brush selection, paintbrush, property smoothing...
  • You can save your ropes mid-simulation and instantiate them already warm-started.
  • Supports all standard Unity colliders.
  • Automatic camera culling: non-visible ropes do not update their simulation.

Obi Fluid

Obi Fluid is a fully-fledged 2D and 3D realtime fluid simulator for Unity.

  • All physical properties or the fluid are adjustable: surface tension, stickiness, vorticity...
  • Fluids can adhere to surfaces, form drops, split and merge...
  • Advect passive particles trough the fluid: bubbles, foam, dust...
  • Custom emitter shapes.
  • Two-way rigid body interaction.
  • Modular solver: don't waste performance, all parameters are exposed.
  • Supports high density ratios in multiphase simulations.
  • You can save your fluids mid-simulation and instantiate them already warm-started.
  • Supports many types of colliders
  • Automatic camera culling: non-visible fluids do not update their simulation.
