Prerequisite

Requirements:

• python3 >= 3.7
• git >= 2.0.0
• gcc >= 8.1 or Visual Studio 2017 or above (Windows)
• cmake >= 3.14
• conan >= 1.19
• Graphics driver that supports Vulkan 1.1.124
• RTX 20 series graphics card.

Ubuntu:

sudo apt install -y git gcc cmake make
pip install conan

Windows:

Set-ExecutionPolicy RemoteSigned -scope CurrentUser
iwr -useb get.scoop.sh | iex
scoop install python git gcc cmake
pip install conan

Add aditional conan repo:

conan remote add conan-center https://conan.bintray.com
conan remote add bincrafters https://api.bintray.com/conan/bincrafters/public-conan
conan remote add wumo https://api.bintray.com/conan/wumo/public

Build with cmake:

mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build . --config Release

Architecture

Getting Started

Draw a green box

#include "sim/graphics/renderer/deferred/deferred.h"
#include "sim/graphics/model/materials.h"

using namespace sim::graphics;

auto main(int argc, const char **argv) -> int {

  // resolution 1920x1080 and title "Getting..."
  Deferred app{{1920, 1080, "Getting Started"}};

  auto &camera = app.camera();
  camera.location = {10, 10, 10};

  auto &light = app.light(0);
  light.location = {0, 100, 100, 0};

  auto &mm = app.modelManager();
  /**
   * mesh -> shape
   * material -> color/metal/glass, etc.
   * model -> prototype
   * modelInstance -> instance of some prototype
   */
  auto boxMesh = mm.newMeshes([&](MeshBuilder &builder) {
    builder.box({0.0, 0.0, 0.0}, {1.0, 0.0, 0.0}, {0.0, 1.0, 0.0}, 1.0);
  });
  auto greenMaterial = mm.newMaterial(material::Green, PBR{0.3f, 0.4f});
  auto greenBoxModel = mm.newModel(
    [&](ModelBuilder &builder) { builder.addMeshPart(boxMesh[0], greenMaterial); });
  auto greenBox1 = mm.newModelInstance(greenBoxModel);

  // after adding model instances, you have to call app.updateModels() to enable
  // drawing these instances.
  app.updateModels();
  app.run();
}

The result is:
