IBLGLEnvBaker

public IBLGLEnvBaker(RenderManager rm,
 AssetManager am,
 Image.Format format,
 Image.Format depthFormat,
 int env_size,

Create a new IBL env baker

Parameters:

rm - The render manager used to render the env scene

am - The asset manager used to load the baking shaders

format - The format of the color buffers

depthFormat - The format of the depth buffers

env_size - The size in pixels of the output environment cube map (eg. 1024)

specular_size - The size in pixels of the output specular cube map (eg. 1024)

irradiance_size - The size in pixels of the output irradiance cube map (eg. 512)

brtf_size - The size in pixels of the output brtf map (eg. 512)
