What is this ?

This is a precompiled version with everything it needs to run the executable.
It was compiled for Windows 10 X86-64, fully written in C++.

How to use ?

Simply drop a .obj file directly onto Scop.exe, or run Scop.exe through shell with the model's path as first argument as such :

./Scop ./some/model/path.obj

Key Binding

  • [⇦ ⇨ ⇧ ⇩]/[Mouse + Left-Click]/[Gamepad Left Stick] Move camera in FPS way
  • [Scroll mouse up/down] Zoom out/in
  • [LCtrl + [Keypad +/-]] Scale up/down model
  • [Page Up/Down]/[Gamepad Right/Left Trigger] Move camera up/down
  • [Left Shift] Speed up movements/scaling
  • [Space]/[Gamepad Y] Cycle through environments
  • [LAlt + Enter] Switch fullscreen
  • [Q]/[Gamepad A] Cycle through quality levels
  • [R]/[Gamepad B] Stop Object Rotation

Features

  • This program features real time Physically based rendering for .obj models.
  • It features image based lighting using irradiance maps and a custom BRDF Lookup Table (replaceable).
  • It's inspired by Unreal Engine 4 workflow and allows for metallic, roughness and specular (F0).
  • The Specular channel on the material allows for more various materials, such as lackered plastics for instance.
  • You can specify an heigth texture to enable steep parallax mapping.
  • Here, Specular channels are slightly different from Blinn-Phong's specular channel, it influences the material's reflectivity and behavior regarding light as it is used as a precomputed F0 value. A plastic material with a Specular of vec3(1, 1, 1) will have a behavior close to metallic materials, but will have a diffuse channel, unlike metallic material. In order to have "normal" plastic, it is recommended to either leave Ni and Ks empty, use Ni 1.5 or Ks 0.04 0.04 0.04
  • Extra values have been added to mtl files, allowing for physically based materials :
Nr [float] //roughness value
Nm [float] //metallic value
Np [float] //parallax factor
map_Nr [./relative/path] //roughness map
map_Nm [./relative/path] //metallic map
map_Nh [./relative/path] //heigth map
map_No [./relative/path] //ambient occlusion map (1 == full occlusion)
