3Dinator

A 3D engine made completely from scratch using OpenGL, cglm and now introducing miniaudio

Setup

Preparing /inc

  • Adding glfw and cglm (miniaudio is optional)
mkdir inc
cd inc
git clone https://github.com/recp/cglm
git clone https://github.com/glfw/glfw
git clone https://github.com/mackron/miniaudio
  • Adding glad
    • Generate files through webservice
    • Put them on inc/glad
    • Also add a CMakeLists.txt:
cmake_minimum_required(VERSION 3.16)
project(glad)

add_library(glad)
target_sources(glad PRIVATE src/glad.c)
target_include_directories(glad PUBLIC include)

Those meshes were made manually, so this bottle
is more amazing than the whole code

Since I'm using .obj files now, I'll let the bottle live here

Mesh bottle = {
