Detailed Description

This class is a merge of an orthographic space and a specific viewport. The orthographic space defines the world coordinate system. The viewport defines the area to wich the content of the orthographic space is projected.

Parameters:

	left	plane
	right	plane
	bottom	plane
	top	plane
	x	postion of the lower left corner of the projection rectangle
	y	postion of the lower left corner of the projection rectangle
	width	of the projection rectangle
	height	of the projection rectangle

void OrthographicCamera::getLocalWorldCoordinates (  int &  x, int &  y )

Compute the position of x and y on the orthographic space. This method is useful to compute the mouse postion in the world coordinates. Parameters: [in]  x  position in screen space [in]  y  position in screen space [out]  x  position in the current orthographic space [out]  y  position in the current orthographic space Definition at line 26 of file OrthographicCamera.cpp. Referenced by Histogram::onLeftMouseClick(), and Histogram::onMouseDrag().

void OrthographicCamera::startCamera (  int  x, int  y, int  width, int  height )

Enter the orthographic projection with the current bounds of the space defined by left, right, bottom and top plane at the given screen coordinate x,y,width, height. Definition at line 35 of file OrthographicCamera.cpp. References OrthographicSpace::setOrthographicProjection().

void OrthographicCamera::startCamera (   )

Enter the orthographic projection with the current bounds of the space defined by left, right, bottom and top plane. at the current defined screen coordinate x,y,width, height. starting the camera also push the GL_VIEWPORT bit to the stack. Definition at line 42 of file OrthographicCamera.cpp. References OrthographicSpace::setOrthographicProjection(). Referenced by Histogram::render(), and ColorCubePanel::render().

void OrthographicCamera::stopCamera (   )

Reset the projection pops the last matrix from the stack. Definition at line 49 of file OrthographicCamera.cpp. References OrthographicSpace::resetProjection(). Referenced by Histogram::render(), and ColorCubePanel::render().
