Method Detail

newShader

public static R2ShaderTranslucentInstanceBillboardedType<R2RefractionMaskedDeltaParameters> newShader(com.io7m.jcanephora.core.api.JCGLShadersType in_shaders,
                                                                                                      R2ShaderPreprocessingEnvironmentReadableType in_shader_env,
                                                                                                      R2IDPoolType in_pool)

Construct a new shader.

Parameters:

in_shaders - A shader interface

in_shader_env - A shader preprocessing environment

in_pool - The ID pool

Returns:

A new shader

shaderParametersType

public Class<R2RefractionMaskedDeltaParameters> shaderParametersType()

Specified by:

shaderParametersType in interface R2ShaderUsableType<R2RefractionMaskedDeltaParameters>

Returns:

The shader parameter type

onReceiveViewValues

public void onReceiveViewValues(com.io7m.jcanephora.core.api.JCGLInterfaceGL33Type g,
                                R2ShaderParametersViewType view_parameters)

Description copied from interface: R2ShaderTranslucentInstanceBillboardedUsableType

Set shader values that are derived from the current view.

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

Specified by:

onReceiveViewValues in interface R2ShaderTranslucentInstanceBillboardedUsableType<R2RefractionMaskedDeltaParameters>

Parameters:

g - An OpenGL interface

view_parameters - The view parameters

onValidate

public void onValidate()
                throws R2ExceptionShaderValidationFailed

Description copied from interface: R2ShaderUsableType

Validate the shader prior to executing a draw call. This method exists so that shader implementations can check that the caller has called all required methods before drawing.

Specified by:

onValidate in interface R2ShaderUsableType<R2RefractionMaskedDeltaParameters>

Throws:

R2ExceptionShaderValidationFailed - If validation fails

onReceiveMaterialValues

public void onReceiveMaterialValues(com.io7m.jcanephora.core.api.JCGLInterfaceGL33Type g,
                                    R2ShaderParametersMaterialType<R2RefractionMaskedDeltaParameters> mat_parameters)

Description copied from interface: R2ShaderTranslucentInstanceBillboardedUsableType

Set material values.

This method will be called once for each group of instances that use the material M.

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

Specified by:

onReceiveMaterialValues in interface R2ShaderTranslucentInstanceBillboardedUsableType<R2RefractionMaskedDeltaParameters>

Parameters:

g - A texture interface

mat_parameters - The material parameters

suggestedBlendState

public Optional<com.io7m.jcanephora.renderstate.JCGLBlendState> suggestedBlendState()

Description copied from interface: R2ShaderTranslucentUsableType

A specification of the blending state with which this shader is intended to be used. An empty value indicates that blending is intended to be disabled.

Specified by:

suggestedBlendState in interface R2ShaderTranslucentUsableType<R2RefractionMaskedDeltaParameters>

Returns:

The blending configuration with which this shader is intended to be used
