Published : 012 – Framebuffers and SSAO

I just published a new Episode in my OpenGL & Vulkan Podcast:

012 – Framebuffers and SSAO
Understanding Framebuffer and SSAO.

http://opengl-trainer.de/podscats/folgen/012_Framebuffers_and_SSAO.mp3

Framebuffer:
framebuffer

SSAO

 glGenFramebuffers( 1, &fb );
glGenTextures( 1, &color );
glGenRenderbuffers( 1 , &depth );

glBindFramebuffer( GL_FRAMEBUFFER , fb );

glBindTexture( GL_TEXTURE_2D, color);
glTexImage2D(   GL_TEXTURE_2D,
0,
GL_RGBA,
fbo_width, fbo_height,
0,
GL_RGBA,
GL_UNSIGNED_BYTE,
NULL);

glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR );
glFramebufferTexture2D( GL_DRAW_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D, color, 0 );

glBindRenderbuffer( GL_RENDERBUFFER, depth );
glRenderbufferStorage( GL_RENDERBUFFER, GL_DEPTH_COMPONENT24, fbo_width, fbo_height );
glFramebufferRenderbuffer( GL_DRAW_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, depth );

I just published a new Episode in my OpenGL & Vulkan Podcast:

011 – Lights and Shadows
About Lights and Shadows in 3D Worlds.

http://opengl-trainer.de/podscats/folgen/011_Lights_and_Shadows.mp3

OpenGL Lights:
Light types

   vec3 L = normalize( LightPosition );  
   vec3 N = normalize( VertexNormal ); 

   float LightIntense = max( dot( N , L ) , 0.0 );  

   gl_FragColor = Color * LightIntense ;
