WIP

OVERVIEW

openFrameworks addon to easily test, learn, and use the new PBR features from the new OF 0.12+ releases.

(You should use the GitHub master branch!)

All this code is copied from and hardly based on this OF forum topic.
Original authors: @NickHardeman and @paolo-scoppola.

FEATURES

• Main class ofxSurfingPBR.h is a Scene Manager with default common elements:

  • Two ready-to-use editable parametric materials:
    • Material A. For the Plane (floor).
    • Material B. For the other Objects.
  • Default Lights combo:
    • Flexible Point, Directional and Spot.
  • Cubemaps (HDR) files loader.
  • Background color and Sphere/Box container with material.

• Class SurfingMaterial.h: Standalone Materials can be used independently of the main class.

• Class SurfingLights.h: Four bundled lights: Point, Direct, Spot and Area with shadows.

• Class SurfingSceneManager.h: Bundles the lights from SurfingLights.h and allows queuing materials dynamically. Standalone and not loaded by default on ofxSurfingPBR.

• Persistent settings:

  • Optimized auto save on any change.
  • Plane simple material, colors, transforms, snapshots, etc...
  • All materials with full PBR specs.
  • Internal camera.

• Material Randomizers.

  • History browsing workflow.
    • Presets/Snapshots (Store/Recall) explorer system.

• Included 3D models browser/loader class.

• Added Shader for testing/code.

  • Displacement applied to the plane and his material/mesh.

TODO

• Add more Shaders related stuff. / HELP IS WELCOME!
  • Mesh/vertex displacements (not just heightmaps). / TODO
  • Shader Debugger. / TODO

USAGE

EXAMPLE

main.cpp

#include "ofApp.h"
#include "ofMain.h"

int main() {
    ofGLWindowSettings settings;
    settings.setGLVersion(3, 2);

    auto window = ofCreateWindow(settings);

    ofRunApp(window, make_shared<ofApp>());
    ofRunMainLoop();
}

ofApp.h

#pragma once
#include "ofMain.h"

#include "ofxSurfingPBR.h"

class ofApp : public ofBaseApp {
public:
    void setup();
    void draw();

    ofxSurfingPBR pbr;
    void renderScene();
};

ofApp.cpp

void ofApp::setup() {
    pbr.setup();

    // Pass the render scene function
    callback_t f = std::bind(&ofApp::renderScene, this);
    pbr.setFunctionRenderScene(f);
}

void ofApp::draw() {
    pbr.draw();
    pbr.drawGui();
}

void ofApp::renderScene()
{
    // Plane floor
    pbr.drawPlane();

    // Other objects
    pbr.beginMaterial();
    {
        /* DRAW HERE! */
    }
    pbr.endMaterial();
}

DEPENDENCIES

• OF 0.12+.
• ofxSurfingHelpersLite.
  • Helper classes for settings serializers, auto saver, ofxGui customizer, layout helpers, ofDrawBitmapStringBox...etc.
• ofxSurfingCameraSimple.
  • An internal improved ofEasyCam is bundled.
• ofxAssimpModelLoader / OF core
  • Only for the example 2_Example_Models.

REQUERIMENTS

• Download and copy the content of data.zip to the examples or to your projects into /bin/data:
  • Data for any or new projects: bin/data.zip
  • Data for 2_Example_Models: bin/data.zip
  • Data for 6_Example_3D_Parts: bin/data.zip
  • Only shaders: bin/dataShaders.zip
  • Folder with all the files: @ MEGA.
• Notice that all the examples should work without the data files too.

/bin/
/data/
/assets/fonts/ ttf,otf | for ofxGui customize
/cubemaps/ exr,hdr,jpg | for CubeMaps
/models/ obj,ply,fbx | for 3d objects
/images/ jpg,png | for Bg sphere texture
/shadersGL2/ frag,vert | used when enabled
/shadersGL3/ frag,vert | used when enabled

TESTED SYSTEMS

• Windows 11 / VS 2022 / OF 0.12+ @ GitHub master branch
