Method Detail

onReceiveBoundGeometryBufferTextures

void onReceiveBoundGeometryBufferTextures(com.io7m.jcanephora.core.api.JCGLInterfaceGL33Type g,
                                          R2GeometryBufferUsableType gbuffer,
                                          com.io7m.jcanephora.core.JCGLTextureUnitType unit_albedo,
                                          com.io7m.jcanephora.core.JCGLTextureUnitType unit_specular,
                                          com.io7m.jcanephora.core.JCGLTextureUnitType unit_depth,
                                          com.io7m.jcanephora.core.JCGLTextureUnitType unit_normals)

Set the bound geometry buffer textures for the current shader.

This method will be called exactly once between calls to R2ShaderUsableType.onActivate(com.io7m.jcanephora.core.api.JCGLInterfaceGL33Type) and R2ShaderUsableType.onValidate().

Parameters:

g - An OpenGL interface

gbuffer - The geometry buffer

unit_albedo - The texture unit to which the geometry buffer's albedo/emissive texture is bound

unit_specular - The texture unit to which the geometry buffer's specular texture is bound

unit_depth - The texture unit to which the geometry buffer's depth/stencil texture is bound

unit_normals - The texture unit to which the geometry buffer's normal

onReceiveValues

void onReceiveValues(com.io7m.jcanephora.core.api.JCGLInterfaceGL33Type g,
                     R2ShaderParametersLightType<M> light_parameters)

Set light values.

This method will be called once for each light that uses the current shader.

This method will be called after a call to R2ShaderUsableType.onActivate(com.io7m.jcanephora.core.api.JCGLInterfaceGL33Type) and before a call to R2ShaderUsableType.onValidate().

Parameters:

g - An OpenGL interface

light_parameters - The light parameters
