Overview of this book

If you‘re fascinated by the complexities of animating video game characters and are curious about the transformation of model files into 3D avatars and NPCs that can explore virtual worlds, then this book is for you. In this new edition, you’ll learn everything you need to know about game animation, from a simple graphical window to a large crowd of smoothly animated characters. First, you’ll learn how to use modern high-performance graphics, dig into the details of how virtual characters are stored, and load the models and animations into a minimalistic game-like application. Then, you’ll get an overview of the components of an animation system, how to play the animations and combine them, and how to blend from one animation into another. You’ll also get an introduction to topics that will make your programming life easier, such as debugging your code or stripping down the graphical output. By the end of this book, you’ll have gained deep insights into all the parts of game animation programming and how they work together, revealing the magic that brings life to the virtual worlds on your screen.

Adding ImGui to the OpenGL and Vulkan renderers

To use ImGui in our code, we need a couple of files from the ImGui GitHub repository at https://github.com/ocornut/imgui

Download the following files to a folder named imgui:

  • imconfig.h
  • imgui.cpp
  • imgui.h
  • imgui_draw.cpp
  • imgui_internal.h
  • imgui_tables.cpp
  • imgui_widgets.cpp
  • imstb_rectpack.h
  • imstb_textedit.h
  • imstb_truetype.h

These downloaded files are the backend-independent code, containing the implementations of the widgets. We have to include them in our project for ImGui to work in general.

For the GLFW input backend, two additional files are required. Download these two files and put them into the imgui folder:

  • imgui_impl_glfw.cpp
  • imgui_impl_glfw.h

To include the GLFW backend, this line will be needed:

#include <imgui_impl_glfw.h>

You can find the code for this section in the chapter05 folder’s 01_opengl_ui subfolder for OpenGL and 05_vulkan_ui...
