lights_camera >> A basic opengl lighting example by Pete Werner 2013 https://github.com/petewerner/generative/tree/master/lights_camera and this is working on 0.8.4 lightTest1 >> test about specular light lightTest2 >> test about basic light features and culling lightTest3 >> test about directional light and setOrientation lightTest4 >> test to compare three light types which are point light, spot light, and directional light lightTest5 >> test about the balance between diffuse light, specular light, and ambient light and check how it looks with different resolution of sphere. each value can be changed with GUI lightTest6 >> test about attenuation of light and you can change each attenuation factor which are constant, linear, and quadratic with GUI lightTest7 >> test about lighting for 3d model which include plane type model, non-plane type model and low polygon model. You can check smoothLighting and separateSpecularLight, and you can enable/disable both of them with GUI. lightTest8 >> test about specular color, diffuse color,and ambient color for light VS specular color, diffuse color,and ambient color for material(I found a bug about glEnable(GL_COLOR_MATERIAL), see line 98 in ofApp.cpp to check about this and I commented out all code about it) Git issue about this is here #1
