Class IBLBuilder

java.lang.Object

net.mgsx.gltf.scene3d.utils.IBLBuilder

All Implemented Interfaces:

com.badlogic.gdx.utils.Disposable

public class IBLBuilder
extends java.lang.Object
implements com.badlogic.gdx.utils.Disposable

Quick procedural IBL environment generation. Should be disposed when no longer used. IBL generated by this class are accurate, some fast approximation are performed to provide a quick way to setup an IBL environment. For accurate IBL, see: https://learnopengl.com/PBR/IBL/Specular-IBL and https://learnopengl.com/PBR/IBL/Diffuse-irradiance and related tools to generate them from HDRIs.

dispose

public void dispose()

Specified by:

dispose in interface com.badlogic.gdx.utils.Disposable

buildEnvMap

public com.badlogic.gdx.graphics.Cubemap buildEnvMap(int size)

Create an environment map, to be used with SceneSkybox

Parameters:

size - base size (width and height) for generated cubemap

Returns:

generated cubemap, caller is responsible to dispose it when no longer used.

buildIrradianceMap

public com.badlogic.gdx.graphics.Cubemap buildIrradianceMap(int size)

Creates an irradiance map, to be used with PBRCubemapAttribute.DiffuseEnv

Parameters:

size - base size (width and height) for generated cubemap

Returns:

generated cubemap, caller is responsible to dispose it when no longer used.

buildRadianceMap

public com.badlogic.gdx.graphics.Cubemap buildRadianceMap(int mipMapLevels)

Creates an radiance map, to be used with PBRCubemapAttribute.SpecularEnv generated cubemap contains mipmaps in order to perform roughness in PBR shading

Parameters:

levels - mipMapLevels how many mipmaps level, eg. 10 levels produce a 1024x1024 cubemap with mipmaps.

Returns:

generated cubemap, caller is responsible to dispose it when no longer used.
