materialPBRExample

Learning Objectives

This example demonstrates how to use setup a PBR material and scene with a camera. It demonstrates the use of a cube map with textures.

You will learn how to..

• setup a cube map and load a HDR image into it.
• configure materials for PBR
• use an ofEasyCam
• use a material and change its properties inside begin()

Pay attention to..

• the define USE_CUBE_MAP
• material.begin(); and the for loops inside it.
• material.setRoughness(0.05);

Expected Behavior

When launching this app, you should see 3 rows and 5 columns of spheres. The top row changes the metalness. The middle row changes the roughness of metallic spheres. The bottom row changes the reflectance of non-metallic spheres.

Instructions for use:

• Press 1,2,3 to change the rendering of the cube map.
• Click and drag to move camera.
• Try commenting out //cubeMap.load("dancing_hall_2k.exr", 512, true ); in ofApp.cpp in setup();
• Try commenting out //#define USE_CUBE_MAP in ofApp.h
