clear_caches()

void blender::ocio::GPUShaderBinder::clear_caches

(

)

const

Clear caches when configuration changes.

Definition at line 597 of file gpu_shader_binder.cc.

construct_display_shader()

virtual void blender::ocio::GPUShaderBinder::construct_display_shader ( internal::GPUDisplayShader & display_shader ) const

protectedpure virtual

Construct display shader matching requested parameters. The shader has its cache variables (input color space name, view, display, look, whether curve mapping is used or not).

Implemented in blender::ocio::FallbackGPUShaderBinder.

Referenced by display_bind().

construct_scene_linear_shader()

virtual void blender::ocio::GPUShaderBinder::construct_scene_linear_shader ( internal::GPUDisplayShader & display_shader ) const

protectedpure virtual

Construct display shader which will only perform the to-scene-linear part of conversion, leaving the to-display a no-op function.

Implemented in blender::ocio::FallbackGPUShaderBinder.

Referenced by to_scene_linear_bind().

create_gpu_shader()

bool blender::ocio::GPUShaderBinder::create_gpu_shader ( internal::GPUDisplayShader & display_shader, StringRefNull fragment_source, Span< std::array< StringRefNull, 2 > > additional_defines )

staticprotected

Create GPU shader for the given display shader. Returns true if the shader was successfully created.

Definition at line 457 of file gpu_shader_binder.cc.

display_bind()

bool blender::ocio::GPUShaderBinder::display_bind

(

const GPUDisplayParameters &

display_parameters

)

const

Bind GPU shader which performs conversion from the given color space to the display space. Drawing happens in the same immediate mode as when GPU_SHADER_3D_IMAGE_COLOR shader is used.

Returns true if the GPU shader was successfully bound.

Definition at line 386 of file gpu_shader_binder.cc.

to_scene_linear_bind()

bool blender::ocio::GPUShaderBinder::to_scene_linear_bind	(	StringRefNull	from_colorspace,
		bool	use_predivide ) const

Configures and bind GPU shader for conversion from the given space to scene linear. Drawing happens in the same immediate mode as when GPU_SHADER_3D_IMAGE_COLOR shader is used.

Returns true if the GPU shader was successfully bound.

unbind()

void blender::ocio::GPUShaderBinder::unbind

(

)

const

Unbind previously bound GPU shader.

If the shader was not bound by neither display_bind() nor to_scene_linear_bind() the behavior is undefined.
