The Renderer class provides an interface for objects that wish to render graphics on the screen.
The render() function will be called on each Renderer object every vblank; if double-buffering is enabled, this will be immediately before the framebuffer is flipped.
The Renderer class also provides a number of convenience functions for drawing graphical primitives. You are not required to use these functions; you may use direct framebuffer access, the text console (if wit::UseConsole is enabled), GX (if wit::UseGX is enabled), or third-party graphics libraries for rendering.

| wit::Renderer::Renderer | ( | ) |
Constructs a new Renderer.
Definition at line 46 of file renderer.cpp.
| wit::Renderer::~Renderer | ( | ) | [virtual] |
Destroys the Renderer.
Definition at line 60 of file renderer.cpp.
Draws a line on the screen in the selected color.
This is an overloaded member function provided for convenience.
Definition at line 216 of file renderer.cpp.
| void wit::Renderer::drawLine | ( | float | x1, |
| float | y1, | ||
| float | x2, | ||
| float | y2, | ||
| const GXColor & | color | ||
| ) |
Draws a line on the screen in the selected color.
Definition at line 199 of file renderer.cpp.
| void wit::Renderer::drawPoint | ( | const Point & | p, |
| const GXColor & | color | ||
| ) |
Draws a point on the screen in the selected color.
This is an overloaded member function provided for convenience.
Definition at line 191 of file renderer.cpp.
| void wit::Renderer::drawPoint | ( | float | x, |
| float | y, | ||
| const GXColor & | color | ||
| ) |
Draws a point on the screen in the selected color.
Definition at line 176 of file renderer.cpp.
| void wit::Renderer::drawPoints | ( | const Polygon & | poly, |
| const GXColor & | color | ||
| ) |
Draws a series of points on the screen in the specified color.
Definition at line 264 of file renderer.cpp.
| void wit::Renderer::drawPolygon | ( | const Polygon & | poly, |
| const GXColor & | color | ||
| ) |
Draws a polygon on the screen in the specified color.
Definition at line 282 of file renderer.cpp.
| void wit::Renderer::drawRect | ( | const Rect & | rect, |
| const GXColor & | color | ||
| ) |
Draws a rectangle on the screen in the specified color.
Definition at line 224 of file renderer.cpp.
| void wit::Renderer::fillPolygon | ( | const Polygon & | poly, |
| const GXColor & | color | ||
| ) |
Draws a polygon on the screen and fills it with the specified color.
Note that this function will only accurately fill convex polygons whose points are specified in clockwise order.
Definition at line 305 of file renderer.cpp.
| void wit::Renderer::fillRect | ( | const Rect & | rect, |
| const GXColor & | color | ||
| ) |
Draws a rectangle on the screen and fills it with the specified color.
Definition at line 245 of file renderer.cpp.
| void wit::Renderer::render | ( | ) | [pure virtual] |
Implement this function to perform whatever steps are necessary to draw the Renderer's content on the screen.
To render in another thread, you may use this function to signal a rendering thread to begin processing, or you may ignore this function and use waitForRendered() to control the event loop when rendering is complete.
| float wit::Renderer::scale | ( | ) | const |
Returns the current scaling factor applied to the convenience functions for this renderer object.
Definition at line 123 of file renderer.cpp.
| void wit::Renderer::setScale | ( | float | mag ) |
Sets the scaling factor applied to the convenience functions for this renderer object.
The default value of 1.0 performs no scaling.
Definition at line 135 of file renderer.cpp.
| void wit::Renderer::setTranslation | ( | float | x, |
| float | y | ||
| ) |
Sets the translation applied to the convenience functions for this renderer object.
The default value of 0.0 for both horizontal and vertical translations performs no translation.
Definition at line 167 of file renderer.cpp.
| float wit::Renderer::translateX | ( | ) | const |
Returns the horizontal translation applied to the convenience functions for this renderer object.
Definition at line 145 of file renderer.cpp.
| float wit::Renderer::translateY | ( | ) | const |
Returns the vertical translation applied to the convenience functions for this renderer object.
Definition at line 155 of file renderer.cpp.
| void wit::Renderer::waitForRendering | ( | ) | [virtual] |
If you are performing rendering in another thread, implement this function to block the main event loop until the rendering is complete.
The default implementation does nothing.
