Constructor & Destructor Documentation

GLRenderer

(

)

Constructor of GLRenderer.

(

)

[virtual]

Destructor of GLRenderer.

Member Function Documentation

void enableBlending

(

bool

blendingEnabled

)

[virtual]

Enables or disables the blending of this GLRenderer.

Parameters:

blendingEnabled

true to enable the blending, false to disable it

Reimplemented in GLLineTrailRenderer.

Definition at line 156 of file SPK_GLRenderer.h.

GLuint getDestBlendingFunction

(

)

const

Gets the destination blending function of this GLRenderer.

Returns:

the source destination function of this GLRenderer

Definition at line 182 of file SPK_GLRenderer.h.

GLuint getSrcBlendingFunction

(

)

const

Gets the source blending function of this GLRenderer.

Returns:

the source blending function of this GLRenderer

Definition at line 177 of file SPK_GLRenderer.h.

GLuint getTextureBlending

(

)

const

Gets the texture blending function of this GLRenderer.

Returns:

the texture blending function of this GLRenderer

Definition at line 187 of file SPK_GLRenderer.h.

void initBlending

(

)

const [protected]

Inits the blending of this GLRenderer.

Definition at line 192 of file SPK_GLRenderer.h.

void initRenderingHints

(

)

const [protected]

Inits the rendering hints of this GLRenderer.

Since:

1.04.00

Definition at line 203 of file SPK_GLRenderer.h.

bool isBlendingEnabled

(

)

const

Tells whether blending is enabled for this GLRenderer.

Returns:

true if blending is enabled, false if it is disabled

Definition at line 172 of file SPK_GLRenderer.h.

static void restoreGLStates

(

)

[static]

Restores the openGL states.

This method restores the openGL states at the values they were at the last call of saveGLStates().

static void saveGLStates

(

)

[static]

Saves the current openGL states.

This method saves all the states that are likely to be modified by a GLRenderer.
Use restoreGLStates() to restore the states.

Note that for one saveGLStates call, a call to restoreGLStates must occur. In case of several saveGLStates with no restoreGLStates, the restoreGLStates is called priorly in an implicit way.

virtual void setBlending

(

BlendingMode

blendMode

)

[virtual]

Sets the blending mode of this renderer.

This is a generic method that allows to set most common blending modes in a generic way. However renderers can implement method to give more control over the blending mode used.

Parameters:

blendMode

: the blending mode to use

Since:

1.04.00

Implements Renderer.

void setBlendingFunctions	(	GLuint	src,
		GLuint	dest
	)

Sets the blending functions of this GLRenderer.

the blending functions are one of the openGL blending functions.

Parameters:

	src	: the source blending function of this GLRenderer
	dest	: the destination blending function of this GLRenderer

Definition at line 161 of file SPK_GLRenderer.h.

void setTextureBlending

(

GLuint

textureBlending

)

Sets the texture blending function of this GLRenderer.

the texture blending function is one of the openGL texture blending functions.

Parameters:

textureBlending

: the texture blending function of this GLRenderer
