Transform Feedback
Using transform feedback, it is possible to capture vertex or geometry shader outputs and write these values to buffers (RE_VertexArrays). Method to add or remove shader outputs should be called before the shader is linked, otherwise they will cause a re-link of the shader. Note that relinking with clear out any uniform values, so these buffers should be set up early.
void	addCaptureGeometry (RE_Geometry *object, bool give_ownership=false)
	Specify an RE_Geometry to collect data from Transform Feedback. Specify a geometry object to hold all the arrays for transform feedback. You retain ownership of the object unless 'give_ownership' is true. If no object is attached when the shader is linked, one will be created for you (with ownership maintained by this shader).

void RE_Shader::addCaptureGeometry	(	RE_Geometry *	object,
		bool	give_ownership = `false`
	)

Specify an RE_Geometry to collect data from Transform Feedback. Specify a geometry object to hold all the arrays for transform feedback. You retain ownership of the object unless 'give_ownership' is true. If no object is attached when the shader is linked, one will be created for you (with ownership maintained by this shader).

bool RE_Shader::addFeedbackBuffer ( const char * attrib_name )

Specify a generic attribute to capture during transform feedback.

RE_ShaderStage* RE_Shader::addShader	(	RE_Render *	r,
		RE_ShaderType	stype,
		const char *	shader_source,
		const char *	shader_name,
		int	codeversion,
		UT_String *	messages = `nullptr`,
		bool	print_source = `true`,
		RE_ShaderLanguage	lang = `RE_SHADER_LANGUAGE_GLSL`,
		bool	preprocess = `false`
	)

loadShader() loads a shader from an ASCII file. addShader() is used when the source is already available. 'messages' returns the warnings & errors (if any) from shader compilation. Multiple shaders can be attached to the same shader type; it is expected that one is the main shader, and others are functions.

virtual void RE_Shader::applyShader	(	RE_Render *	r,
		bool	update_re = `true`
	)

pure virtual

Implemented in RV_VKShader.

virtual bool RE_Shader::attachShader	(	RE_Render *	r,
		RE_ShaderStage *	obj,
		UT_String *	messages = `nullptr`
	)

virtual

Individual Shader objects can be created separately and attached. returns true if the shader was attached, and false if it was already attached.

Reimplemented in RV_VKShader.

virtual bool RE_Shader::attachStorageBlock ( const RE_UniformBlockHandle & block )

inlinevirtual

Attach a shader storage block to the binding point corresponding to its name. Shader storage blocks should be created with createStorageBlock().

Definition at line 755 of file RE_Shader.h.

virtual bool RE_Shader::attachStorageBuffer ( RE_VertexArray * raw_buffer )

inlinevirtual

Attach a GL buffer to the shader storage block binding point that shares its name (getAttributeName()). This method is for simple storage blocks, such as "buffer blockname { vec4 color[]; }".

Definition at line 766 of file RE_Shader.h.

virtual bool RE_Shader::attachUniformBlock ( RE_UniformBlock * )

inlinevirtual

Attach an RE_UniformBlock to this shader Attach a single uniform block to the shader. The shader owns the block while attached, and will delete it if the shader is deleted, or may delete it if linkShaders() is called and it is no longer in use. If you want to cache a block, detach it when you're done with the shader. If a block with the same name is already attached to this shader, it will be deleted.

loadShader() loads a shader from an ASCII file. addShader() is used when the source is already available. 'messages' returns the warnings & errors (if any) from shader compilation. Multiple shaders can be attached to the same shader type; it is expected that one is the main shader, and others are functions.

void RE_Shader::setRegisterProgram ( bool register_program )

If true, register this shader so that RE_Shader::getShader() can find this shader (default is true).

void RE_Shader::setShadingRate ( fpreal rate )

inline

For multisampled framebuffers, this sets the fraction of samples that should be shaded by a fragment shader, from 0.0 to 1.0. For example, setting this to 0.5 would guarentee at least 4 color samples for a 8x multisample buffer. The default is 0.0 (1 color sample, N coverage) This only has an effect on GL4 hardware. It is ignored unless RE_EXT_SAMPLE_SHADING is supported.

Definition at line 358 of file RE_Shader.h.

void RE_Shader::setTextureFormat ( RE_TextureCompress format )

inline

Override texture compression for texture bound via bindTextureMap()

		const UT_StringHolder &	uniform_name,
		RE_Texture *	texture,
		int *	saved_idx = `0`

assign a bindless texture to its handle uniform. 'texture' must have a texture handle, and uniform_name must refer to a texture handle.

void RE_Shader::setTextureScale ( float sc )

inline

Scale by a constant scale factor for textures bound via bindTextureMap()

Definition at line 924 of file RE_Shader.h.

bool RE_Shader::setUniformTextureUnit	(	RE_Render *	r,
		const UT_StringHolder &	uniform_name,

Set a binding point for the given sampler.

virtual bool RE_Shader::setVertexInput	(	RE_Render *	r,

void RE_Shader::useDefaultAttribMap ( bool enable = true )

If true, this shader follows the default Houdini attribute map.

void RE_Shader::useExplicitAttribMap ( bool enable = true )

If true, this shader defines its own attribute locations in shader code Do not move any attributes.

void RE_Shader::useHoudiniLibraryFuncs ( )

If true, this shader may use Houdini's builtin functions.

virtual bool RE_Shader::validateShader	(	RE_Render *	r,
		UT_String *	messages = `nullptr`
	)

virtual

Ensures that the shader can run given the current GL state. This mostly deals with texture bindings matching what is expected by the shader. If this returns false, the shader will not run, and 'messages' can be used to fetch the reason.
