This handles adding expressions, animating the given expressions, and such things. Author: Fungmeista Definition at line 37 of file glexpressiongraph.h. Member Function Documentation int GLExpressionGraph::expressionCount (    )  const [inline]   Returns the number of expressions the graph is holding. This includes hidden expressions. Definition at line 74 of file glexpressiongraph.h. virtual Cartesian3DCoord2DVector GLExpressionGraph::getValues (  FungParser &   , GLfloat *    = 0, GLfloat *    = 0 )  [protected, pure virtual]   This class uses the 2-dimensional vector returned from this function to draw the expression and export it do DXF. The 2-dimensional vector of Cartesian3DCoord's should be all of the vertices on the graph. Implemented in GLCylindricalGraph, GLFunctionGraph, and GLPolarGraph. void GLExpressionGraph::nextFrameReady (    )  [protected, virtual]   Classes that implement this class need to implement this function. This function is called everytime the next frame is ready and the subclass should implement an animation with it Implements Animator. Definition at line 380 of file glexpressiongraph.cpp. References Animator::animatorValue(). void GLExpressionGraph::setResolution (  int    percent )  [slot]   Sets the resolution of the graph to the specified percent of possible resolution. This accepts a double between 0 and 100. If less than or greater than 0 or 100, it sets the resolution to 0 or 100 respectively. Definition at line 354 of file glexpressiongraph.cpp. References setXRes(), and setYRes(). void GLExpressionGraph::setXRes (  GLfloat    f )  [inline]   Sets the resolution in the x direction. Warning: Any small values for this functions can significantly reduce the speed of the program. Also, values less than 0.05 could cause errors due to lack of system resources, although it depends on your system. Definition at line 79 of file glexpressiongraph.h.
