Conclusion/Next Steps

Welcome to 3D Art Optimization for Mobile Applications! In this introductory project, we will review the course's main learning objectives, discuss the practice of optimization, and identify the optimization tools available at your disposal.

Introduction/Optimization and Profiling

This project will highlight optimizations for 3D models that can make a game more efficient while maintaining aesthetic intent, improving the performance and experience on mobile devices. 

Geometry

This project will highlight the different implementation considerations and optimizations that take advantage of a Texture’s flexibility. When given the correct settings and applied correctly over their many use cases, Textures play a major role in achieving your desired visual effects. 

Textures

Lighting is one of the most important aspects of real-time 3D visuals. It can set the mood, guide interactions, and identify goals and objectives. In this project, you will learn about and compare the differences between the available lights and light modes that you can use in your 3D mobile application.
