Method Detail

newShader

public static R2ShaderFilterType<R2ShaderFilterBoxBlurParameters> 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 - Shader sources

in_pool - The ID pool

Returns:

A new shader

shaderParametersType

public Class<R2ShaderFilterBoxBlurParameters> shaderParametersType()

Specified by:

shaderParametersType in interface R2ShaderUsableType<R2ShaderFilterBoxBlurParameters>

Returns:

The shader parameter type

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<R2ShaderFilterBoxBlurParameters>

Throws:

R2ExceptionShaderValidationFailed - If validation fails

onReceiveFilterValues

public void onReceiveFilterValues(com.io7m.jcanephora.core.api.JCGLInterfaceGL33Type g,
                                  R2ShaderParametersFilterType<R2ShaderFilterBoxBlurParameters> parameters)

Description copied from interface: R2ShaderFilterUsableType

Set filter values.

This method will be called exactly once between calls to R2ShaderUsableType.onActivate(JCGLInterfaceGL33Type) and R2ShaderUsableType.onValidate().

Specified by:

onReceiveFilterValues in interface R2ShaderFilterUsableType<R2ShaderFilterBoxBlurParameters>

Parameters:

g - A texture interface

parameters - The current filter parameters
