Unigine::WidgetSpriteViewport Class
| Header: | #include <UnigineWidgets.h> |
| Inherits from: | WidgetSprite |
This class is used to create virtual monitors that display data from arbitrary cameras in the world. This widget is used to render the whole scene, with all engine post-processes like HDR, DOF, motion blur, glow, etc. Unlike WidgetSpriteNode, this widget does not support alpha channel masking.
Notice
By default, the sprite viewport is rendered at the same frame rate as the main Unigine viewport. For it to be rendered at different frame rate (for example, lower one in order to decrease the rendering load), use setIFps().
The following sample demonstrates the usage of the WidgetSpriteViewport class:
WidgetSpriteViewport Class
Members
static WidgetSpriteViewportPtr create ( const Ptr<Gui> & gui, int width, int height ) #
Constructor. Creates a new viewport sprite with given properties and adds it to the specified GUI.Arguments
- const Ptr<Gui> & gui - GUI, to which the new sprite will belong.
- int width - Width of the sprite.
- int height - Height of the sprite.
static WidgetSpriteViewportPtr create ( int width, int height ) #
Constructor. Creates a new viewport sprite with given properties and adds it to the Engine GUI.Arguments
- int width - Width of the sprite.
- int height - Height of the sprite.
void setAspectCorrection ( bool correction ) #
Sets the aspect correction for the WidgetSpriteViewport. true enables correction, false disables.Arguments
- bool correction - true to enable aspect correction, false to disable.
bool isAspectCorrection ( ) const#
Returns the value indicating if the aspect correction enabled for WidgetSpriteViewport.Return value
true if the aspect correction enabled, otherwise false.void setCamera ( const Ptr<Camera> & camera ) #
Copies parameters of the given Camera instance.Arguments
Ptr<Camera> getCamera ( ) const#
Copies the instance of camera.Return value
Camera instance.void setIFps ( float ifps ) #
Sets a constant frame duration used to render sprite viewport. It can be used to decrease the frame rate to get higher performance. (For example, if the widget is used to create a TV set, lowered frame rate makes no visual difference, but allows for faster rendering of the scene.)Arguments

Frame duration in seconds (1 / FPS).void setModelview ( const Math::Mat4 & modelview ) #

Projection matrix.void setReflectionViewportMask ( int mask ) #

- SKIP_SRGB
void setTextureHeight ( int height ) #
Sets the height of the texture buffer used for a widget. This affects the widget size accordingly.Arguments
- int height - Height of the texture buffer size.
int getTextureHeight ( ) const#
Returns the height of the texture buffer used for a widget that affects the widget size.Return value
Height of the texture buffer size.void setTextureWidth ( int width ) #
Sets the width of the texture buffer used for a widget. This affects the widget size accordingly.Arguments
- int width - Width of the texture buffer size.
int getTextureWidth ( ) const#
Returns the width of the texture buffer used for a widget that affects the widget size.Return value
Width of the texture buffer size.void setViewportMask ( int mask ) #
Sets a bit mask for rendering into the viewport. Nodes are rendered in this sprite viewport if their masks match this one.Arguments
- int mask - Integer, each bit of which is a mask.
int getViewportMask ( ) const#
Returns the current bit mask for rendering into the viewport. Nodes are rendered in the sprite viewport if their masks match this one.Return value
Integer, each bit of which is a mask.void appendSkipFlags ( int flags ) #
Appends a new skip flag without rewriting already set.Arguments
- int flags - A skip flag. Available flags:
- SKIP_SHADOWS
- SKIP_VISUALIZER
- SKIP_POSTEFFECTS
- SKIP_DYNAMIC_REFLECTIONS
- SKIP_VELOCITY_BUFFER
- SKIP_SRGB
int checkSkipFlags ( int flags ) #
Checks if given flags are already set.Arguments
- int flags - A skip flag. Available flags:
- SKIP_SHADOWS
- SKIP_VISUALIZER
- SKIP_POSTEFFECTS
- SKIP_DYNAMIC_REFLECTIONS
- SKIP_VELOCITY_BUFFER
- SKIP_SRGB
Return value
1 if flag/flags already set, otherwise 0.void removeSkipFlags ( int flags ) #
Removes the given skip flag without affecting other set flags.Arguments
- int flags - A skip flag to be removed. Available flags:
- SKIP_SHADOWS
- SKIP_VISUALIZER
- SKIP_POSTEFFECTS
- SKIP_DYNAMIC_REFLECTIONS
- SKIP_VELOCITY_BUFFER

void renderImage ( const Ptr<Image> & image ) #
Renders the sprite viewport into the image.Arguments
void setImage ( const Ptr<Image> & image, int dynamic = 0 ) #
Sets a loaded into memory image for the first (bottom) layer of the sprite. This layer always exists in the sprite. An additional flag can be set in case the sprite image is going to be updated often or even each frame (for optimized memory management).Warning
This method is intended for changing the sprite's background texture and is valid only for the base WidgetSprite class. It cannot be used for the WidgetSpriteViewport!
Arguments
- const Ptr<Image> & image - Pointer to the image.
- int dynamic - Positive number if the image will be updated each frame; otherwise, 0.
const Ptr<Image> & getImage ( ) const#
Returns the loaded into memory image that is currently set for the first (bottom) layer of the sprite.Warning
This method is valid only for the base WidgetSprite class. It cannot be used for the WidgetSpriteViewport!
Return value
Pointer to the image.void setRender ( const Ptr<Texture> & texture, int flipped = 0 ) #
Sets a texture to be rendered for the first (bottom) layer of the sprite.Warning
This method is intended for changing the sprite's background texture and is valid only for the base WidgetSprite class. It cannot be used for the WidgetSpriteViewport!
Arguments
Ptr<Texture> getRender ( ) const#
Returns the pointer to the texture that is currently set for the first (bottom) layer of the sprite.Warning
This method is valid only for the base WidgetSprite class. It cannot be used for the WidgetSpriteViewport!
Return value
Pointer to the texture.void setUseTAAOffset ( bool offset ) #
Sets a value indicating if skipping render mode check is enabled for using TAA. Can be used to ensure proper TAA calculation when rendering mode for the Viewport is set to RENDER_DEPTH.Arguments
