Advanced Graphics Introduction

forzaHorizons3

What is this module about?

  • Advanced Graphics Techniques

  • Graphics on other platforms

doom 2016 99 final

Expected experience

  • Building on:

    • Games Programming

    • Graphics

    • Object-Oriented Programming

    • Game Engine Architectures

Teaching Style

  • Practice-led

    • lectures will introduce concepts, techniques, things to think about

    • effective learning will require lots of programming engagement

  • There are many "advanced graphics" techniques, you’ll be expected to read and research about them for your needs

  • Ask questions, query norms

  • Discuss with each other

    • Constructive Critique

  • Critique my code too

Dissecting a Frame

Assignments

  • Two assignments

    • Assignment 1 = 60% weight

    • Assignment 2 = 40% weight

  • More technical showcase than complete game

  • Space for personal expression and portfolio

  • You’ll need to go beyond the taught content for high marks

    • this is MComp level - self-study/research is expected

Assignment 1

  • Demonstrating various Advanced Graphics Techniques

  • Demonstrating good performance characteristics

Assignment 2

  • retarget onto another platform

    • WebGL

    • Android

    • iOS

    • RaspberryPi

  • considerations of the new platform

  • good code practice

    • single source

Workshops

  • Sequences of exercises/tutorials

    • Developing the skills you’ll integrate together for your assignments

  • You can (should) start the first assignment soon

Module Overview

  • Embedded through out

    • C++, libraries, engines and other languages

    • Modern C++

    • Efficiency

    • Good Programming Practice

    • Software Engineering Best Practices, e.g.

      • Versioning

      • Reading Documentation

Assembling a toolset

  • C++ (required)

  • Conan.io (required)

  • git (recommended!!)

Assembling a toolset 2

  • SDL2 (required)

    • Windowing

    • GL context

    • input handling

  • SDL2_image

    • image loading

  • SDL2_ttf

    • text

  • Assimp

    • model loading

C and C++

  • Why are we looking using C++ for building games

  • Relationship of C and C++

  • Performance focus of this module

cpp

Build Systems

  • conan.io

  • cmake

cmake
conan small

Module overview

  • We’ll cover a variety of Advanced Graphics aspects

    • rendering techniques

    • non-PC targets

    • associate tools/skills

Libraries and Cross-platform

  • building libraries for cross-platform

  • using libraries cross-platform

Geometry Shaders

Tesselation shaders

Model loading

Model animation

  • Skeletal

  • Morph Targets

Render to texture

  • and video textures

Shadows

Logging

  • why

    • vs printf or cout

    • why start with logging

  • how

Time and Time Budgets

  • issues related to time

    • fps, deadlines

    • latency, jitter

  • measuring time

  • "hard real-time"

Debugging/Tracing

  • Apitrace

Recommended Reading/Resources

  • OpenGL SuperBible - at least 2014 edition (physical copies in the library)

  • Game engine architecture - Jason Gregory 2014

  • OpenGL ES 3.0 programming guide Check reading list on Blackboard for complete list
