Field Details

manualSRGB

public PBRShaderConfig.SRGB manualSRGB

Enable conversion of SRGB space textures into linear space in shader. Should be PBRShaderConfig.SRGB.NONE if your textures are already in linear space or automatically converted by OpenGL when using GL30.GL_SRGB format.

transmissionSRGB

public PBRShaderConfig.SRGB transmissionSRGB

Enable conversion of SRGB space frame buffer into linear space in shader for transmission source. Should be PBRShaderConfig.SRGB.NONE if the transmission frame buffer is already in linear space. By default, transmission source is considered rendered with gamma correction (sRGB space).

mirrorSRGB

public PBRShaderConfig.SRGB mirrorSRGB

Enable conversion of SRGB space frame buffer into linear space in shader for mirror source. Should be PBRShaderConfig.SRGB.NONE if the mirror frame buffer is already in linear space. By default, mirror source is considered rendered with gamma correction (sRGB space).

manualGammaCorrection

public boolean manualGammaCorrection

Enable/Disable gamma correction. Since gamma correction should only be done once as a final step, this should be disabled when you want to apply it later (eg. in case of post process lighting calculation). It also should be disabled when drawing to SRGB framebuffers since gamma correction will be automatically done by OpenGL. Default is true.

DEFAULT_GAMMA

public static final float DEFAULT_GAMMA

Default gamma factor that gives good results on most monitors.

• Constant Field Values

gamma

public float gamma

Gamma value used when manualGammaCorrection is enabled. Default is 2.2 which is a standard value that gives good results on most monitors

glslVersion

public String glslVersion

string to prepend to shaders (version), automatic if null

numVertexColors

public int numVertexColors

Max vertex color layers. Default PBRShader only use 1 layer, custom shaders can implements more.

prefix

public String prefix

Some custom GLSL code to inject in shaders. If not null it will be added after #version
