Member Function Documentation

static TypeHandle getClassType ( ) [static]

Reimplemented from TypedWritableReferenceCount.

bool getErrorFlag ( )

Returns true if the shader contains a compile-time error.

This doesn't tell you whether or not the shader is supported on the current video card.

Filename const getFilename ( ShaderType type )

Return the Shader's filename for the given shader type.

Filename const getFilename ( )

Return the Shader's filename for the given shader type.

ShaderLanguage getLanguage ( )

Returns the shader language in which this shader was written.

static ShaderUtilization getShaderUtilization ( ) [static]

This flag returns SUT_none, SUT_basic, or SUT_advanced and controls the automatic generation of shaders.

It is initialized from the config variable of the same name, but it can be subsequently adjusted.

string getText ( ShaderType type )

Return the Shader's text for the given shader type.

string getText ( )

Return the Shader's text for the given shader type.

static bool haveShaderUtilization ( ) [static]

If true, then get_shader_utilization has been set using set_shader_utilization.

If false, then get_shader_utilization simply returns the config variable of the same name.

bool isPrepared ( PreparedGraphicsObjects prepared_objects )

Returns true if the shader has already been prepared or enqueued for preparation on the indicated GSG, false otherwise.

static Shader load	(	Filename const	file,
		ShaderLanguage	lang
	)		`[static]`

Loads the shader with the given filename.

static Shader load ( Filename const file ) [static]

Loads the shader with the given filename.

static Shader load	(	ShaderLanguage	lang,
		Filename const	vertex,
		Filename const	fragment,
		Filename const	geometry,
		Filename const	tess_control,
		Filename const	tess_evaluation
	)		`[static]`

This variant of Shader::load loads all shader programs separately.

static Shader load	(	ShaderLanguage	lang,
		Filename const	vertex,
		Filename const	fragment,
		Filename const	geometry,
		Filename const	tess_control
	)		`[static]`

This variant of Shader::load loads all shader programs separately.

static Shader load	(	ShaderLanguage	lang,
		Filename const	vertex,
		Filename const	fragment,
		Filename const	geometry
	)		`[static]`

This variant of Shader::load loads all shader programs separately.

static Shader load	(	ShaderLanguage	lang,
		Filename const	vertex,
		Filename const	fragment
	)		`[static]`

This variant of Shader::load loads all shader programs separately.

static Shader make	(	ShaderLanguage	lang,
		string	vertex,
		string	fragment,
		string	geometry,
		string	tess_control,
		string	tess_evaluation
	)		`[static]`

Loads the shader, using the strings as shader bodies.

static Shader make	(	ShaderLanguage	lang,
		string	vertex,
		string	fragment,
		string	geometry,
		string	tess_control
	)		`[static]`

Loads the shader, using the strings as shader bodies.

static Shader make	(	ShaderLanguage	lang,
		string	vertex,
		string	fragment,
		string	geometry
	)		`[static]`

Loads the shader, using the strings as shader bodies.

static Shader make	(	ShaderLanguage	lang,
		string	vertex,
		string	fragment
	)		`[static]`

Loads the shader, using the strings as shader bodies.

static Shader make	(	string	body,
		ShaderLanguage	lang
	)		`[static]`

Loads the shader, using the string as shader body.

static Shader make ( string body ) [static]

Loads the shader, using the string as shader body.

prepare ( PreparedGraphicsObjects prepared_objects )

Indicates that the shader should be enqueued to be prepared in the indicated prepared_objects at the beginning of the next frame.

This will ensure the texture is already loaded into texture memory if it is expected to be rendered soon.

Use this function instead of prepare_now() to preload textures from a user interface standpoint.

ShaderContext prepareNow	(	PreparedGraphicsObjects	prepared_objects,
		GraphicsStateGuardianBase	gsg
	)

Creates a context for the shader on the particular GSG, if it does not already exist.

Returns the new (or old) ShaderContext. This assumes that the GraphicsStateGuardian is the currently active rendering context and that it is ready to accept new textures. If this is not necessarily the case, you should use prepare() instead.

Normally, this is not called directly except by the GraphicsStateGuardian; a shader does not need to be explicitly prepared by the user before it may be rendered.

bool release ( PreparedGraphicsObjects prepared_objects )

Frees the texture context only on the indicated object, if it exists there.

Returns true if it was released, false if it had not been prepared.

int releaseAll ( )

Frees the context allocated on all objects for which the texture has been declared.

Returns the number of contexts which have been freed.

static setShaderUtilization ( ShaderUtilization utl ) [static]

Set this flag to SUT_none, SUT_basic, or SUT_advanced to limit panda's automatic shader generation facilities.
