◆ ImplicitBufferAttachment

enum osg::Camera::ImplicitBufferAttachment

Explicit control over implicit allocation of buffers when using FBO. Implicit buffers are automatically substituted when user have not attached such buffer.

Camera may set up two FBOs: primary Render FBO and secondary Resolve FBO for multisample usage. So in practice we have two masks defined for the Camera: implicitBufferAttachmentRenderMask implicitBufferAttachmentResolveMask They can be set together by setImplicitBufferAttachmentMask method, or separately by setImplicitBufferAttachmentRenderMask and setImplicitBufferAttachmentResolveMask.

Camera defaults are USE_DISPLAY_SETTINGS_MASK which means that by default Camera chooses to substitute buffer attachments as defined by DisplaySettings.

Usually DisplaySettings implicit buffer attachment selection defaults to: DEPTH and COLOR for both primary (Render) FBO and seconday Multisample (Resolve) FBO ie: IMPLICIT_DEPTH_BUFFER_ATTACHMENT | IMPLICIT_COLOR_BUFFER_ATTACHMENT

If these masks are not changed and user did not attach depth buffer and/or color buffer to Camera, then OSG implicitly substitutes these buffers. By default it does not implicitly allocate a stencil buffer. Use implicit buffer attachment masks to override default behavior: to turn off DEPTH or COLOR buffer substitution or to enforce STENCIL buffer substitution.

Note that both values are ignored if not using FBO. Note that the second mask value is ignored if not using MSFBO.

Set to an orthographic projection. See OpenGL glOrtho for documentation further details.

◆ setProjectionMatrixAsOrtho2D()

void osg::Camera::setProjectionMatrixAsOrtho2D	(	double	left,
		double	right,
		double	bottom,
		double	top )

Set to a 2D orthographic projection. See OpenGL glOrtho2D documentation for further details.

◆ setProjectionMatrixAsPerspective()

void osg::Camera::setProjectionMatrixAsPerspective	(	double	fovy,
		double	aspectRatio,
		double	zNear,
		double	zFar )

Create a symmetrical perspective projection, See OpenGL gluPerspective documentation for further details. Aspect ratio is defined as width/height.

◆ setProjectionResizePolicy()

void osg::Camera::setProjectionResizePolicy ( ProjectionResizePolicy policy )

inline

Set the policy used to determine if and how the projection matrix should be adjusted on window resizes.

References _projectionResizePolicy.

◆ setReadBuffer()

void osg::Camera::setReadBuffer ( GLenum buffer )

inline

Set the read buffer for any required copy operations to use. Note, a buffer value of GL_NONE is used to specify that the rendering back-end should choose the most appropriate buffer.

References _readBuffer, osg::CullSettings::applyMaskAction(), and osg::CullSettings::READ_BUFFER.

◆ setRenderer()

void osg::Camera::setRenderer ( osg::GraphicsOperation * rc )

inline

Set the Rendering object that is used to implement rendering of the subgraph.

References _renderer.

◆ setRenderingCache()

void osg::Camera::setRenderingCache ( osg::Object * rc )

inline

Set the Rendering cache that is used for cached objects associated with rendering of subgraphs.

References _renderingCache.

◆ setRenderOrder()

void osg::Camera::setRenderOrder	(	RenderOrder	order,
		int	orderNum = 0 )

inline

Set the rendering order of this camera's subgraph relative to any camera that this subgraph is nested within. For rendering to a texture, one typically uses PRE_RENDER. For Head Up Displays, one would typically use POST_RENDER.

References _renderOrder, and _renderOrderNum.
